This is version 1.1.0 of the Linux Standard Base Specification. An implementation of this version of the specification may not claim to be an implementation of the Linux Standard Base unless it has successfully completed the compliance process as defined by the Free Standards Group.
The Linux Standard Base (LSB) defines a system interface for compiled applications and a minimal environment for support of installation scripts. Its purpose is to enable a uniform industry standard environment for high-volume applications conforming to the LSB.
The LSB defines a binary interface for application programs that are compiled and packaged for LSB-conforming implementations on many different hardware architectures. Since a binary specification must include information specific to the computer processor architecture for which it is intended, it is not possible for a single document to specify the interface for all possible LSB-conforming implementations. Therefore, the LSB is a family of specifications, rather than a single one.
The LSB is composed of two basic parts: A common part of the specification describes those parts of the interface that remain constant across all hardware implementations of the LSB, and an architecture-specific part of the specification describes the parts of the specification that are specific to a particular processor architecture. Together, the generic LSB and the architecture-specific supplement for a single hardware architecture provide a complete interface specification for compiled application programs on systems that share a common hardware architecture.
This document is the generic LSB. It must be used in conjunction with an architecture-specific supplement. Whenever a section of this specification must be supplemented by architecture-specific information, this document includes a reference to the architecture supplement. Architecture supplements may also contain additional information that is not referenced here.
This document should be used in conjunction with the documents it references. This document enumerates the system components it includes, but descriptions of those components may be included entirely or partly in this document, partly in other documents, or entirely in other reference documents. For example, the section that describes system service routines includes a list of the system routines supported in this interface, formal declarations of the data structures they use that are visible to applications, and a pointer to the underlying referenced specification for information about the syntax and semantics of each call. Only those routines not described in standards referenced by this document, or extensions to those standards, are described in the detail. Information referenced in this way is as much a part of this document as is the information explicitly included here.
The specifications listed below are referenced in whole or in part by the Linux Standard Base. Such references may be normative or non-normative; a reference to specification shall only be considered normative if it is explicitly cited as such. The LSB may make normative references to a portion of these specifications (that is, to define a specific function or group of functions); in such cases, only the explicitly referenced portion of the specification is to be considered normative.

The complete LSB specification is composed of this generic LSB specification and the supplemental processor-specific specification for a particular processor architecture. These two documents constitute a specification that should be used in conjunction with the publicly-available standards documents it references. The LSB enumerates the system components it includes, but descriptions of those components may be included entirely in the LSB, partly in the LSB and partly in other documents, or entirely in other reference documents.
This document.
An application written to include only the system routines, commands, and other resources included in this document, and that has been compiled into an executable file that has the formats and characteristics specified for such files in this document, and whose behavior complies, installs, and is executed in the environment with the rules given in this document.
An implementation that provides the binary system interface for applications described in this document.
An application which has been written to include system routines, commands, or other resources not included in this document, or which has been compiled into a format different from those specified here, or which does not behave as specified in this document.
An implementation satisfying the following requirements:
The implementation shall implement fully the architecture described in the hardware manual for the target processor architecture.
The implementation shall be capable of executing compiled applications having the format and using the system interfaces described in this document.
The implementation shall provide libraries containing the interfaces specified by this document, and shall provide a dynamic linking mechanism that allows these interfaces to be attached to applications at runtime. All the interfaces shall behave as specified in the normative references and requirements of this document.
The map of virtual memory provided by the implementation shall conform to the requirements of this document.
The implementation's low-level behavior with respect to function call linkage, system traps, signals, and other such activities shall conform to the formats described in this document.
The compilation system shall compile source code into executable files having the formats and characteristics specified in this document.
The implementation shall provide all of the mandatory interfaces in their entirety.
The implementation may provide one or more of the optional interfaces. Each optional interface that is provided shall be provided in its entirety. The product documentation shall state which optional interfaces are provided.
The implementation shall provide all files and utilities specified as part of this document in the format defined here and in other referenced documents. All commands and utilities shall behave as required by this document. The implementation shall also provide all mandatory components of an application's runtime environment that are included or referenced in this document.
The implementation, when provided with standard data formats and values at a named interface, shall provide the behavior defined for those values and data formats at that interface. However, a conforming implementation may consist of components which are separately packaged and/or sold. For example, a vendor of a conforming implementation might sell the hardware, operating system, and windowing system as separately packaged items.
The implementation may provide additional interfaces with different names. It may also provide additional behavior corresponding to data values outside the standard ranges, for standard named interfaces.
An application with the following characteristics:
Its executable files are either shell scripts or object files in the format defined for the Object File Format system interface.
Its object files participate in dynamic linking as defined in the Program Loading and Linking System interface.
It employs only the instructions, traps, and other low-level facilities defined in the Low-Level System interface as being for use by applications.
If it requires any optional interface defined in this document in order to be installed or to execute successfully, the requirement for that optional interface is stated in the application's documentation.
It does not use any interface or data format that is not required to be provided by a conforming implementation, unless:
If such an interface or data format is supplied by another application through direct invocation of that application during execution, that application is in turn an LSB-compliant application.
The use of that interface or data format, as well as its source, is identified in the documentation of the application.
It must not use any values for a named interface that are reserved for vendor extensions.
An LSB-compliant application is expected to have no dependencies on any vendor extensions to this document. The most common such extensions are additional function entry points and additional libraries other than the ones defined in this document. If an application requires such extensions, it is not portable, since other LSB-conforming implementations may not provide those extensions.
An LSB-compliant application is required to use system services on the implementation on which it is running, rather than importing system routines from some other implementation. Thus, it must link dynamically to any routines in the implementation that perform system traps to kernel services.
It is to be expected that some applications may be companion applications to other applications. For example, a query application may be a companion to a database application; a preprocessor may be an adjunct to one or more compilers; a data reformatter may convert data from one document manager to another. In such cases, the application may or may not be LSB-compliant, regardless of whether the other application on which it is dependent is LSB-compliant. If such an application merely uses data produced by another application, the application's compliance is independent of the other application's compliance. If such an application actually invokes another application during execution (as, for example, a third-party math library), the invoking application is LSB-compliant only if it also constitutes a LSB-compliant application in combination with the invoked application.
A file that is read by an interpreter (e.g., awk). The first line of the shell script includes a reference to its interpreter binary.
Describes a permissible optional feature or behavior available to the user or application. The feature or behavior is mandatory for an implementation that conforms to this document. An application can rely on the existence of the feature or behavior.
Describes a value or behavior that is not defined by this document but is selected by an implementor. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence of the value or behavior. An application that relies on such a value or behavior cannot be assured to be portable across conforming implementations. The implementor shall document such a value or behavior so that it can be used correctly by an application.
Same as implementation-dependent.
Describes a feature or behavior that is optional for an implementation that conforms to this document. An application should not rely on the existence of the feature or behavior. An application that relies on such a feature or behavior cannot be assured to be portable across conforming implementations.
To avoid ambiguity, the opposite of may is expressed as need not, instead of may not.
Describes a feature or behavior that is mandatory for an application or user. An implementation that conforms to this document shall support this feature or behavior.
Describes a feature or behavior that is mandatory for an implementation that conforms to this document. An application can rely on the existence of the feature or behavior.
For an implementation that conforms to this document, describes a feature or behavior that is recommended but not mandatory. An application should not rely on the existence of the feature or behavior. An application that relies on such a feature or behavior cannot be assured to be portable across conforming implementations.
For an application, describes a feature or behavior that is recommended programming practice for optimum portability.
Describes the nature of a value or behavior not defined by this document which results from use of an invalid program construct or invalid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations.
Describes the nature of a value or behavior not specified by this document which results from use of a valid program construct or valid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations.
Same meaning as shall; shall is the preferred term.
LSB-conforming implementations shall support the object file Executable and Linking Format (ELF), which is defined by the following documents:

The following sections types are defined in the System V Application Binary Interface, Edition 4.1.
Table 3-1.

| SHT_DYNSYM | 0xb | |
| SHT_FINI_ARRAY | 0xf | This section contains an array of pointers to termination functions, as described in `Initialization and Termination Functions' in Chapter 5. Each pointer in the array is taken as a parameterless procedure with a void return. |
| SHT_HASH | 0x5 | The section holds a symbol hash table. Currently, an object file may have only one hash table, but this restriction may be relaxed in the future. See `Hash Table' in the Chapter 5 for details. |
| SHT_HIPROC | 0x7fffffff | Values in this inclusive range are reserved for processor-specific semantics. |
| SHT_HIUSER | 0xffffffff | This value specifies the upper bound of the range of indexes reserved for application programs. Section types between SHT_LOUSER and SHT_HIUSER may be used by the application, without conflicting with current or future system-defined section types. |

This section contains a list of global constructor function pointers.
This section contains a list of global destructor function pointers.
This section contains information necessary for frame unwinding during exception handling. The format is the same as for .debug_frame as described by DWARF2.
This section contains the Symbol Version Table.
This section contains the Version Definitions.
This section contains the Version Requirments.
This section holds relocation information, as described in `Relocation'. These relocations are applied to the .dyn section.
This section contains debugging information. The contents are not specified as part of the LSB.
This section contains strings associated with the debugging infomation contained in the .stab section.
This chapter defines how names are mapped from the source symbol to the object symbol.
Because of the immaturity of the C++ ABI (for name mangling, exception handling, and other such issues), we do not standardize any libraries for C++ in this version of the Linux Standard Base. [1]
In a future version of this specification, name mangling rules will be specified so that C++ symbols can be mapped into symbol names in the object file.
This chapter describes the Symbol Versioning mechanism. All ELF objects may provide or depend on versioned symbols. Symbol Versioning is implemented by 3 section types: SHT_GNU_versym, SHT_GNU_verdef, and SHT_GNU_verneed.
The term "Elfxx" means "Elf32" or "Elf64" depending on the architecture.
Versions are described by strings. The structures that are used for symbol versions also contain a member that holds the ELF hashing values of the strings. This allows for more efficient processing.
The Symbol Version Table is contained in the special section .gnu.version which has a section type of SHT_GNU_versym. This section has the same number of entries as the Dynamic Symbol Table.
This section contains an array of elements of type Elfxx_Half. Each entry specifies the version defined for or required by the corresponding symbol in the Dynamic Symbol Table.
The values in the Symbol Version Table are unique to the object in which they are located. These values are identifiers that are provided by the the vna_other member of the Elfxx_Vernaux structure or the vd_ndx member of the Elfxx_Verdef structure.
The values 0 and 1 are reserved.
The symbol is local, not available outside the object.
The symbol is defined in this object and is globally available.
All other values are used to identify version strings located in one of the other Symbol Version sections. The value itself is not the version associated with the symbol. The string identified by the value defines the version of the symbol.
Symbol definitions are contained in the special section .gnu.version_d which has a section type of SHT_GNU_verdef. The number of entries in this section is contained in the DT_VERDEFNUM entry of the Dynamic Section. The sh_link member of the section header points to the section that contains the strings referenced by this section.

The sh_link member of the section header points to the section that contains the strings referenced by this section.

Dependency name hash value (ELF hash function).
Dependency information flag bitmask.
Object file version identifier used in the .gnu.version symbol version array. Bit number 15 controls whether or not the object is hidden; if this bit is set, the object cannot be used and the static linker will ignore the symbol's presence in the object.
Offset to the dependency name string in the section header, in bytes.
Offset to the next vernaux entry, in bytes.
When loading a sharable object, version definition data from the loaded object is analyzed to assure that it meets the version requirements of the calling object. The dynamic loader retrieves the entries in the caller's Elfxx_Verneed array and attempts to find matching definition information in the loaded Elfxx_Verdef table.
Each object and dependency is tested in turn. If a symbol definition is missing, the loader returns an error. A warning is issued instead of a hard error when the vna_flags bit for VER_FLG_WEAK is set in the Elfxx_Vernaux entry.
When the versions referenced by undefined symbols in the loaded object are found, version availability is certified. The test completes without error and the object is made available.
When symbol versioning is used in an object, relocations extend the performance of definition testing beyond the simple match of symbol name strings: the version of the reference must also equal the name of the definition. The same index that is used in the symbol table can be referenced in the SHT_GNU_versym section, and the value of this index is then used to acquire name data. The corresponding requirement string is retrieved from the Elfxx_Verneed array, and likewise, the corresponding definition string from the Elfxx_Verdef table.
Bit number 15 of the version symbol controls whether or not the object is hidden; if this bit is set, the object cannot be used and the static linker will ignore the symbol's presence in the object.
Results differ in the interaction of objects that variously use symbol versioning.
The object with the reference and the object with the definitions may both use versioning. All described matching is processed in this case. A fatal error is triggered when no matching definition can be found in the object whose name is the one referenced by the vn_name element in the Elfxx_Verneed entry.
The object with the reference may not use versioning, while the object with the definitions does. In this instance, only the definition with index numbers 1 and 2 will be used in the reference match, the same identified by the static linker as the base definition. In infrequent cases where the static linker was not used, as in calls to dlopen(), a version that does not have the base definition index is acceptable as long as it is the only version for which the symbol is defined.
The object with the reference may use versioning, but the object with the definitions specifies none. A matching symbol is accepted in this case. A fatal error is triggered in the unlikely event that a corruption in the required symbols list obscured an outdated object file and caused a match on the object filename in the Elfxx_Verneed entry.
Finally, both the object with the reference and the object with the definitions may not use versioning. The behavior in this instance defaults to pre-existing symbol rules.
LSB-conforming implementations shall support the object file information and system actions that create running programs as specified in the System V Application Binary Interface, Edition 4.1 and the System V Application Binary Interface - DRAFT - April 29, 1998 and as supplemented by this document and an architecture-specific LSB specification.

An array containing the "C" locale strings used by strerror(). This normally should not be used directly. The strerror function provides all the needed functionality.
An array containing the names of the signal names.
This exists only for compatibility. Use strsignal instead (see <string.h>).
When called with the name of an existing file as argument, accounting is turned on and records for each terminating process are appended to filename as it terminates. An argument of NULL causes accounting to be turned off.
BSD process accounting has not been enabled when the operating system kernel was compiled. The kernel configuration parameter controlling this feature is CONFIG_BSD_PROCESS_ACCT.

Adjtime() makes small adjustments to the system time, as returned by gettimeofday(2), advancing or retarding it by the time specified by the timeval delta. If delta is negative, the clock is slowed down by incrementing it more slowly than normal until the correction is complete. If delta is positive, a larger increment than normal is used. The skew used to perform the correction is generally a fraction of one percent. Thus, the time is always a monotonically increasing function. A time correction from an earlier call to adjtime() may not be finished when adjtime() is called again. If olddelta is non-nil, the structure pointed to will contain, upon return, the number of microseconds still to be corrected from the earlier call.
This call may be used by time servers that synchronize the clocks of computers in a local area network. Such time servers would slow down the clocks of some machines and speed up the clocks of others to bring them to the average network time.
The call adjtime() is restricted to the super-user.
An argument points outside the process's allocated address space.
The process's effective user ID is not that of the super-user.
Linux uses David L. Mills' clock adjustment algorithm (see RFC 1305). The system call adjtimex reads and optionally sets adjustment parameters for this algorithm. It takes a pointer to a timex structure, updates kernel parameters from field values, and returns the same structure with current kernel values. This structure is declared as follows:
int modes; /* mode selector */
long offset; /* time offset (usec) */
long freq; /* frequency offset (scaled ppm) */
long maxerror; /* maximum error (usec) */
long esterror; /* estimated error (usec) */
int status; /* clock command/status */
long constant; /* pll time constant */
long precision; /* clock precision (usec) (read only) */
long tolerance; /* clock frequency tolerance (ppm) (read only) */
struct timeval time; /* current time (read only) */
long tick; /* usecs between clock ticks */
};
The modes field determines which parameters, if any, to set. It may contain a bitwise-or combination of zero or more of the following bits:
#define ADJ_OFFSET 0x0001 /* time offset */
#define ADJ_FREQUENCY 0x0002 /* frequency offset */
#define ADJ_MAXERROR 0x0004 /* maximum time error */
#define ADJ_ESTERROR 0x0008 /* estimated time error */
#define ADJ_STATUS 0x0010 /* clock status */
#define ADJ_TIMECONST 0x0020 /* pll time constant */
#define ADJ_TICK 0x4000 /* tick value */
#define ADJ_OFFSET_SINGLESHOT 0x8001 /* old-fashioned adjtime */
Ordinary users are restricted to a zero value for mode. Only the superuser may set any parameters.
On success, adjtimex returns the clock state:
#define TIME_OK 0 /* clock synchronized */
#define TIME_INS 1 /* insert leap second */
#define TIME_DEL 2 /* delete leap second */
#define TIME_OOP 3 /* leap second in progress */
#define TIME_WAIT 4 /* leap second has occurred */
#define TIME_BAD 5 /* clock not synchronized */
On error, -1 is returned, and errno is set appropriately.
buf does not point to writable memory.
buf.mode is non-zero and the user is not super-user.
An attempt is made to set buf.offset to a value outside the range -131071 to +131071, or to set buf.status to a value other than those listed above, or to set buf.tick to a value outside the range 900000/HZ to 1100000/HZ, where HZ is the system timer interrupt frequency.
The alphasort() function can be used as the comparison function for the scandir() function to sort the directory entries into alphabetical order. Its parameters are the two directory entries, a and b, to compare.
The alphasort() function returns an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.
Function to compare two struct dirents alphabetically. This function is like alphasort but it uses the 64bit dirent structure.

The cfsetspeed function is provided for setting the baud rate values in the termios structure. The effects of the function on the terminal as described below do not become effective, nor are all errors detected, until the tcsetattr function is called. Certain values for baud rates set in the termios structure and passed to tcsetattr have special meanings.
The input and output baud rates are found in the termios structure. The unsigned integer speed_t is typdef'd in the include file <termios.h>. The value of the integer corresponds directly to the baud rate being represented, however, the following symbolic values are defined.
#define B0 0

The cfsetspeed function sets both the input and output baud rate in the termios structure referenced by t to speed.
The daemon() function is for programs wishing to detach themselves from the controlling terminal and run in the background as system daemons. Unless the argument nochdir is non-zero, daemon() changes the current working directory to the root (`/'). Unless the argument noclose is non-zero, daemon() will redirect standard input, standard output and standard error to /dev/null.
On error, -1 is returned, and errno is set to any of the errors specified for the library functions fork(2) and setsid(2).
#include <libintl.h>
extern char *dcgettext(const char *domainname,

Used to look up the MSGID in the DOMAINNAME message catalog for the current CATEGORY locale.
The err() function displays a formatted error message on the standard error output. The last component of the program name, a colon character, and a space are output. If the fmt argument is not NULL, the formatted error message, a colon character, and a space are output. The error message string affiliated with the current value of the global variable errno is output. The output is followed by a newline character.
The err() function does not return, but exits with the value of the argument eval.
Error analyzes and optionally disperses the diagnostic error messages produced by a number of compilers and language processors to the source file and line where the errors occurred. It can replace the painful, traditional methods of scribbling abbreviations of errors on paper, and permits error messages and source code to be viewed simultaneously without machinations of multiple windows in a screen editor.
Options are:
Do not touch any files; all error messages are sent to the standard output
The user is queried whether s/he wants to touch the file. A `y' or `n' to the question is necessary to continue. Absence of the -q option implies that all referenced files (except those referring to discarded error messages) are to be touched.
After all files have been touched, overlay the visual editor vi(1) with it set up to edit all files touched, and positioned in the first touched file at the first error. If vi(1) can't be found, try ex(1) or ed(1) from standard places.
Take the following argument as a suffix list. Files whose suffixes do not appear in the suffix list are not touched. The suffix list is dot separated, and `*' wildcards work. Thus the suffix list:
.c.y.foo*.h
allows error to touch files ending with `.c', `.y', `.foo*' and `.y'.
Print out statistics regarding the error categorization. Not too useful.
Error looks at the error messages, either from the specified file name or from the standard input, and:
attempts to determine which language processor produced each error message
determines the source file and line number to which the error message refers
determines if the error message is to be ignored or not
inserts the (possibly slightly modified) error message into the source file as a comment on the line preceding to which the line the error message refers.
Error messages that can't be categorized by language processor or content are not inserted into any file, but are sent to the standard output. Error touches source files only after all input has been read.
Error is intended to be run with its standard input connected via a pipe to the error message source. Some language processors put error messages on their standard error file; others put their messages on the standard output. Hence, both error sources should be piped together into error. For example, when using the csh(1) syntax,
make -s lint | error -q -v
will analyze all the error messages produced by whatever programs make(1) runs when making lint.
Error knows about the error messages produced by: make(1), cc(1), cpp(1), ccom(1), as(1), ld(1), lint(1), pi(1), pc(1), f77(1), and DEC Western Research Modula-2. Error knows a standard format for error messages produced by the language processors, so is sensitive to changes in these formats. For all languages except Pascal, error messages are restricted to be on one line. Some error messages refer to more than one line in more than one files; error will duplicate the error message and insert it at all of the places referenced.
Error will do one of six things with error messages.
Some language processors produce short errors describing which file it is processing. Error uses these to determine the file name for languages that don't include the file name in each error message. These synchronization messages are consumed entirely by error.
Error messages from lint(1) that refer to one of the two lint(1) libraries, /usr/libdata/lint/llib-lc and /usr/libdata/lint/llib-port are discarded, to prevent accidently touching these libraries. Again, these error messages are consumed entirely by error.
Error messages from lint(1) can be nullified if they refer to a specific function, which is known to generate diagnostics which are not interesting. Nullified error messages are not inserted into the source file, but are written to the standard output. The names of functions to ignore are taken from either the file named .errorrc in the users's home directory, or from the file named by the -I option. If the file does not exist, no error messages are nullified. If the file does exist, there must be one function name per line.
Error messages that can't be intuited are grouped together, and written to the standard output before any files are touched. They will not be inserted into any source file.
Error message that refer to a specific file, but to no specific line, are written to the standard output when that file is touched.
Error messages that can be intuited are candidates for insertion into the file to which they refer.
Only true error messages are candidates for inserting into the file they refer to. Other error messages are consumed entirely by error or are written to the standard output. Error inserts the error messages into the source file on the line preceding the line the language processor found in error. Each error message is turned into a one line comment for the language, and is internally flagged with the string `###' at the beginning of the error, and `%%%' at the end of the error. This makes pattern searching for errors easier with an editor, and allows the messages to be easily removed. In addition, each error message contains the source line number for the line the message refers to. A reasonably formatted source program can be recompiled with the error messages still in it, without having the error messages themselves cause future errors. For poorly formatted source programs in free format languages, such as C or Pascal, it is possible to insert a comment into another comment, which can wreak havoc with a future compilation. To avoid this, programs with comments and source on the same line should be formatted so that language statements appear before comments.
Error catches interrupt and terminate signals, and if in the insertion phase, will orderly terminate what it is doing.
Opens the teletype directly to do user querying.
Source files with links make a new copy of the file with only one link to it.
Changing a language processor's format of error messages may cause error to not understand the error message.
Error, since it is purely mechanical, will not filter out subsequent errors caused by floodgating initiated by one syntactically trivial error. Humans are still much better at discarding these related errors.
Pascal error messages belong after the lines affected (error puts them before). The alignment of the \ marking the point of error is also disturbed by error.
Error was designed for work on CRT's at reasonably high speed. It is less pleasant on slow speed terminals, and has never been used on hardcopy terminals.
The errx() function displays a formatted error message on the standard error output. The last component of the program name, a colon character, and a space are output. If the fmt argument is not NULL, the formatted error message, a colon character, and a space are output. The output is followed by a newline character.
The errx() function does not return, but exits with the value of the argument eval.
Apply or remove an advisory lock on an open file. The file is specified by fd. Valid operations are given below:
Shared lock. More than one process may hold a shared lock for a given file at a given time.
Exclusive lock. Only one process may hold an exclusive lock for a given file at a given time.
Unlock.
Don't block when locking. May be specified (by or'ing) along with one of the other operations.
A single file may not simultaneously have both shared and exclusive locks.
fstatfs returns information about a mounted file system. fd is the open file descriptor of any file within the mounted filesystem. buf is a pointer to a statfs structure defined as follows:
long f_type; /* type of filesystem (see below) */
long f_bsize; /* optimal transfer block size */
long f_blocks; /* total data blocks in file system */
long f_bfree; /* free blocks in fs */
long f_bavail; /* free blocks avail to non-superuser */
long f_files; /* total file nodes in file system */
long f_ffree; /* free file nodes in fs */
fsid_t f_fsid; /* file system id */
long f_namelen; /* maximum length of filenames */
long f_spare[6]; /* spare for later */
};
Fields that are undefined for a particular file system are set to 0.
fd is not a valid open file descriptor.
buf points to an invalid address.
An I/O error occurred while reading from or writing to the file system.
The filesystem fd is open on does not support statfs.
The specification for "fwprintf" is as specified in the SUSv2 but with the following differences as listed below.
The gethostbyname() function returns a structure of type hostent for the given host name. Here name is either a host name, or an IPv4 address in standard dot notation, or an IPv6 address in colon (and possibly dot) notation. (See RFC 1884 for the description of IPv6 addresses.) If name is an IPv4 or IPv6 address, no lookup is performed and gethostbyname() simply copies name into the h_name field and its struct in_addr equivalent into the h_addr_list[0] field of the returned hostent structure. If name doesn't end in a dot and the environment variable HOSTALIASES is set, the alias file pointed to by HOSTALIASES will first be searched for name (see hostname(7) for the file format). The current domain and its parents are searched unless name ends in a dot.
The domain name queries carried out by gethostbyname() use a combination of any or all of the name server named(8), a broken out line from /etc/hosts, and the Network Information Service (NIS or YP), depending upon the contents of the order line in /etc/host.conf. (See resolv+(8)). The default action is to query named(8), followed by /etc/hosts.
The hostent structure is defined in <netdb.h> as follows:
char *h_name; /* official name of host */
char **h_aliases; /* alias list */
int h_addrtype; /* host address type */
int h_length; /* length of address */
char **h_addr_list; /* list of addresses */
}
#define h_addr h_addr_list[0] /* for backward compatibility */
The gethostbyname()) functions return the hostent structure or a NULL pointer if an error occurs. On error, the h_errno variable holds an error number.
The getloadavg() function returns the number of processes in the system run queue averaged over various periods of time. Up to nelem samples are retrieved and assigned to successive elements of loadavg[]. The system imposes a maximum of 3 samples, representing averages over the last 1, 5, and 15 minutes, respectively.
int getopt(int argc, char * const argv[], const char *optstring); extern char *optarg; extern int optind, opterr, optopt; |
GNU supports the following extensions of getopt:
int getopt_long(int argc, char * const argv[],
const char *optstring,
const struct option *longopts, int *longindex);
int getopt_long_only(int argc, char * const argv[],
const char *optstring,
const struct option *longopts, int *longindex); |
The getopt() function parses command line arguments. GNU and POSIX specifications for this function vary in the following areas.
GNU specifies that:
an element of argv that starts with "-" (and is not exactly "-" or "--") is an option element.
characters of an option element, aside from the initial "-", are option characters.
POSIX specifies that:
applications using getopt() must obey the following syntax guidelines:
option name is a single alphanumeric character from the portable character set
option is preceded by the "-" delimiter character
options without option-arguments should be accepted when grouped behind one "-" delimiter
each option and option-argument is a separate argument
option-arguments are not optional
all options should precede operands on the command line
the argument "--" is accepted as a delimiter indicating the end of options and the consideration of subsequent arguments, if any, as operands
historical implementations of getopt() support other characters as options as an allowed extension, but applications that use extensions are not maximally portable.
support for multi-byte option characters is only possible when such characters can be represented as type int.
applications that call any utility with a first operand starting with "-" should usually specify "--" to mark the end of the options. Standard utilities that do not support this guideline indicate that fact in the OPTIONS section of the utility description.
GNU specifies that:
if a character is followed by two colons, the option takes an optional arg; if there is text in the current argv-element, it is returned in optarg, otherwise optarg is set to zero.
if optstring contains W followed by a semi-colon, then -W foo is treated as the long option --foo. (Not available with libraries before GNU libc 2.)
getopt_long() works like getopt() except that it also accepts "long options", or, options that are preface with two dashes instead of one.
long option names may be abbreviated if the abbreviation is unique or an exact match for some defined option.
a long option may take a parameter, of the form --arg=param or --arg param.
getopt_long_only() works like getopt_long(), except that both "-" and "--" indicate long option. If an option that starts with "-" (not "--") doesn't match a long option, but does match a short option, it is parsed instead as a short option.
POSIX specifies that:
the -W option is reserved for implementation extensions.
GNU specifies the following getopt() return values:
the next option character is returned, if found successfully.
colon character (":") is returned if a parameter is missing for one of the options.
question mark ("?") is returned if an unknown option character is encountered.
"-1" is returned for the end of the option list.
GNU specifies the following getopt_long() and getopt_long_only() return values:
when short option is recognized, the option character is returned.
when long option is recognized, val is returned if flag is NULL, otherwise, 0 is returned.
error and -1 returns are the same as for getopt().
question mark ("?") is returned for an ambiguous match or an extraneous parameter.
POSIX specifies the following getopt() return values:
the next option character is returned, if found successfully.
colon character (":") is returned if a parameter is missing for one of the options and the first character of opstring is ":".
question mark ("?") is returned if an unknown option character not in optstring is encountered, or if getopt() detects a missing argument and the first character of optstring is not ":".
"-1" is returned for the end of the option list.
GNU specifies that:
if the variable POSIXLY_CORRECT is set, option processing stops as soon as a non-option argument is encountered.
if POSIXLY_CORRECT is set, GNU getopt() conforms to POSIX.2.
the variable _[PID]_GNU_nonoption_argv_flags_ was used by bash 2.0 to communicate to GNU libc which arguments resulted from wildcard expansion and so should not be considered as options. This behavior was removed in bash version 2.01, but the support remains in GNU libc.

The getopt_long() function works like getopt() except that it also accepts long options, started out by two dashes. Long option names may be abbreviated if the abbreviation is unique or is an exact match for some defined option. A long option may take a parameter, of the form --arg=param or --arg param.
longopts is a pointer to the first element of an array of struct option declared in <getopt.h> as
const char *name;

The getopt_long() function returns the option character if the option was found successfully, : if there was a missing parameter for one of the options, ? for an unknown option character, or -1 for the end of the option list.
getopt_long() also returns the option character when a short option is recognized. For a long option, they return val if flag is NULL, and 0 otherwise. Error and -1 returns are the same as for getopt(), plus ? for an ambiguous match or an extraneous parameter.

getopt_long_only() is like getopt_long(), but - as well as -- can indicate a long option. If an option that starts with - (not --) doesn't match a long option, but does match a short option, it is parsed as a short option instead.
The function getopt_long_only() returns the option character if the option was found successfully, : if there was a missing parameter for one of the options, ? for an unknown option character, or -1 for the end of the option list. getopt_long_only() also returns the option character when a short option is recognized. For a long option, they return val if flag is NULL, and 0 otherwise. Error and -1 returns are the same as for getopt(), plus ? for an ambiguous match or an extraneous parameter.
The getprotobyname() function returns a protoent structure for the line from /etc/protocols that matches the protocol name name.
The protoent structure is defined in <netdb.h> as follows:
char *p_name; /* official protocol name */
char **p_aliases; /* alias list */
int p_proto; /* protocol number */
}
The getprotobyname() function returns the protoent structure, or a NULL pointer if an error occurs or the end of the file is reached.
The getprotoent() function reads the next line from the file /etc/protocols and returns a structure protoent containing the broken out fields from the line. The /etc/protocols file is opened if necessary.

The getprotoent() function returns the protoent structure, or a NULL pointer if an error occurs or the end of the file is reached.
The getservbyname() function returns a servent structure for the line from /etc/services that matches the service name using protocol proto.
The servent structure is defined in <netdb.h> as follows:
char *s_name; /* official service name */
char **s_aliases; /* alias list */
int s_port; /* port number */
char *s_proto; /* protocol to use */
}
getservbyname() returns the servent structure, or a NULL pointer if an error occurs or the end of the file is reached.
The getservent() function reads the next line from the file /etc/services and returns a structure servent containing the broken out fields from the line. The /etc/services file is opened if necessary.
The servent structure is defined in <netdb.h> as follows:
char *s_name; /* official service name */
char **s_aliases; /* alias list */
int s_port; /* port number */
char *s_proto; /* protocol to use */
}
getservent() returns the servent structure, or a NULL pointer if an error occurs or the end of the file is reached.
Used to look up the MSGID in the DOMAINNAME message catalog for the current CATEGORY locale. If not found, returns MSGID itself (the default text).
getutent() reads a line from the current file position in the utmp file. It returns a pointer to a structure containing the fields of the line.
#include <glob.h>
int glob64((const char *pattern, int flags,
int (*errfunc) (const char *, int),
glob64_t *pglob)); |
The glob64() function searches for all the pathnames matching pattern according to the rules used by the shell (see glob(7)). No tilde expansion or parameter substitution is done; if you want these, use wordexp(3). The results of a glob64() call are stored in the structure pointed to by pglob, which is a glob64_t which is declared in <glob.h> and includes the following elements defined by POSIX.2 (more may be present as an extension):
The glob64() function is a 64-bit version of glob.
On successful completion, glob64() returns zero. Other possible returns are: GLOB_NOSPACE for running out of memory, GLOB_ABORTED for a read error, and GLOB_NOMATCH for no found matches.
The globfree64() function frees the dynamically allocate storage from an earlier call to glob64().
The globfree64 function is a 64-bit version of globfree.
The initgroups() function initializes the group access list by reading the group database /etc/group and using all groups of which user is a member. The additional group group is also added to the list.
The calling process does not have sufficient privileges.
Insufficient memory to allocate group information structure.
This functions checks whether c, which must have the value of an unsigned char or EOF, falls into a certain character class according to the current locale.
isblank() checks for a blank character; that is, a space or a tab. This function is a GNU extension.
The values returned are nonzero if the character c falls into the tested class, and a zero value if not.
The details of what characters belong into which class depend on the current locale. For example, isupper() will not recognize an A - umlaut as an uppercase letter in the default C locale.
The iswblank function is the wide-character equivalent of the isblank function. It tests whether wc is a wide character belonging to the wide character class "blank".
The wide character class "blank" is a subclass of the wide character class "space".
Being a subclass of the wide character class "space", the wide character class "blank" is disjoint from the wide character class "graph" and therefore also disjoint from its subclasses "alnum", "alpha", "upper", "lower", "digit", "xdigit", "punct".
The wide character class "blank" always contains at least the space character and the control character '\t'.
The iswblank function returns non-zero if wc is a wide character belonging to the wide character class "blank". Otherwise it returns zero.
If wc is a wide character having the character property designated by desc (or in other words: belongs to the character class designated by desc), the iswctype function returns non-zero. Otherwise it returns zero. If wc is WEOF, zero is returned.
desc must be a character property descriptor returned by the wctype function.
iswctype returns non-zero if the wc has the designated property. Otherwise it returns 0.
The specification for "kill" is as specified in the SUSv2 but with the following differences as listed below.
If pid is specified as -1, sig shall not be sent to the calling process. Other than this, the rules in the SUSv2 apply.
Rationale: Linux users/programs expect to exclude the calling process, which is the historic Linux behavior. After an experiment with including the calling process in 2.5.1 Linus has decided to go back to the traditional Linux behavior. Affected programs include killall5 and some versions of shutdown. Another example is the shell command "kill -KILL -1" which is expected to not kill the shell from which it is run. See "What does it mean to signal everybody?", Linux Weekly News, 20 December 2001 ( http://lwn.net/2001/1220/kernel.php3 ).
#include <wchar.h>
size_t mbsnrtowcs(wchar_t *dest, const char **src,
size_t nms, size_t len, mbstate_t *ps); |
The mbsnrtowcs function is like the mbsrtowcs function, except that the number of bytes to be converted, starting at *src, is limited to nms.
If dest is not a NULL pointer, the mbsnrtowcs function converts at most nms bytes from the multibyte string *src to a wide-character string starting at dest. At most len wide characters are written to dest. The state *ps is updated. The conversion is effectively performed by repeatedly calling mbrtowc(dest,*src,n,ps) where n is some positive number, as long as this call succeeds, and then incrementing dest by one and *src by the number of bytes consumed. The conversion can stop for three reasons:
1. An invalid multibyte sequence has been encountered. In this case *src is left pointing to the invalid multibyte sequence, (size_t)(-1) is returned, and errno is set to EILSEQ.
2. The nms limit forces a stop, or len non-L'\0' wide characters have been stored at dest. In this case *src is left pointing to the next multibyte sequence to be converted, and the number of wide characters written to dest is returned.
3. The multibyte string has been completely converted, including the terminating '\0' (which has the side effect of bringing back *ps to the initial state). In this case *src is set to NULL, and the number of wide characters written to dest, excluding the terminating L'\0' character, is returned.
If dest is NULL, len is ignored, and the conversion proceeds as above, except that the converted wide characters are not written out to memory, and that no destination length limit exists.
In both of the above cases, if ps is a NULL pointer, a static anonymous state only known to the mbsnrtowcs function is used instead.
The programmer must ensure that there is room for at least len wide characters at dest.
The mbsnrtowcs function returns the number of wide characters that make up the converted part of the wide character string, not including the terminating null wide character. If an invalid multibyte sequence was encountered, (size_t)(-1) is returned, and errno set to EILSEQ.
The behavior of mbsnrtowcs depends on the LC_CTYPE category of the current locale.
Passing NULL as ps is not multi-thread safe.

#include <string.h>
void *memmem(const void *haystack, size_t haystacklen,
const void *needle, size_t needlelen); |
The memmem() function finds the start of the first occurrence of the substring needle of length needlelen in the memory area haystack of length haystacklen.
The memmem() function returns a pointer to the beginning of the substring, or NULL if the substring is not found.
This function was broken in Linux libraries up to and including libc 5.0.9; there the needle and haystack arguments were interchanged, and a pointer to the end of the first occurrence of needle was returned. Since libc 5.0.9 is still widely used, this is a dangerous function to use.
Both old and new libc's have the bug that if needle is empty haystack-1 (instead of haystack) is returned. And glibc 2.0 makes it worse, and returns a pointer to the last byte of haystack. This is fixed in glibc 2.1.
memrchr() returns a pointer to the last occurrence of the character represented by c in the first n characters of the string represented by s.
opterr is used as a flag to suppress error message generated by getopt(). When opterr is set to 0; it suppresses the error message generated by getopt() when getopt() does not recognize an option character.
optind holds the current index of the array argr[] which contains the command line options being parsed by getopt().
optopt holds the unknown option character when that option character is not recognized by getopt()
#include <signal.h> void psignal(int sig, const char *s); extern const char *const sys_siglist[] |
The psignal() function displays a message on stderr consisting of the string s, a colon, a space, and a string describing the signal number sig. If sig is invalid, the message displayed will indicate an unknown signal.
The array sys_siglist holds the signal description strings indexed by signal number.
setbuffer is an alias for call to setvbuf. It works the same, except that the size of the buffer is up to the caller, rather than being determined by the default BUFSIZ.
setegid sets real and effective group ID's of the current process. Unprivileged users may change the real group ID to the effective group ID and vice-versa.
Prior to Linux 1.1.38, the saved ID paradigm, when used with setegid was broken. Starting at 1.1.38, it is also possible to set the effective group ID from the saved group ID.
Only the super-user may make other changes.
Supplying a value of -1 for either the real or effective group ID forces the system to leave that ID unchanged.
Currently (libc-4.x.x), setegid(egid) is functionally equivalent to setregid(-1, egid).
If the real group ID is changed or the effective group ID is set to a value not equal to the previous real group ID, the saved group ID will be set to the new effective group ID.
The current process is not the super-user and changes other than (i) swapping the effective group ID with the real group ID or (ii) setting one to the value of the other or (iii) setting the effective group ID to the value of the saved group ID was specified.
seteuid sets real and effective user ID's of the current process. Un-privileged users may change the real user ID to the effective user ID and vice-versa.
Prior to Linux 1.1.37, the saved ID paradigm, when used with seteuid was broken.
Starting at 1.1.37, it is also possible to set the effective user ID from the saved user ID.
Only the super-user may make other changes.
Supplying a value of -1 for either the real or effective user ID forces the system to leave that ID unchanged.
Currently seteuid(euid) is functionally equivalent to setreuid(-1, euid).

#include <stdio.h> #include <mntent.h> FILE *setmntent(const char *filename, const char *type); |
This routine is used to access the file system description file /etc/fstab and the mounted file system description file /etc/mtab.
The setmntent() function opens the file system description file filep and returns a file pointer which can be used by getmntent(). The argument type is the type of access required and can take the same values as the mode argument of fopen(3).
The mntent structure is defined in <mntent.h> as follows:
char *mnt_fsname; /* name of mounted file system */
char *mnt_dir; /* file system path prefix */
char *mnt_type; /* mount type (see mntent.h) */
char *mnt_opts; /* mount options (see mntent.h) */
int mnt_freq; /* dump frequency in days */
int mnt_passno; /* pass number on parallel fsck */
};
setutent() rewinds the file pointer to the beginning of the utmp file. It is generally a Good Idea to call it before any of the other functions.

|
A signal function that builds a new signal set by combining the two input sets using logical OR.
When the Linux kernel creates the stack frame for a signal handler, a call to sigreturn is inserted into the stack frame so that the the signal handler will call sigreturn upon return. This inserted call to sigreturn cleans up the stack so that the process can restart from where it was interrupted by the signal.
sigreturn call is used by the kernel to implement signal handlers. It should never be called directly. Better yet, the specific use of the __unused argument varies depending on the architecture.
statfs returns information about a mounted file system. path is the path name of any file within the mounted filesystem.
buf is a pointer to a statfs structure defined as follow:
long f_type; /* type of filesystem (see below) */
long f_bsize; /* optimal transfer block size */
long f_blocks; /* total data blocks in file system */
long f_bfree; /* free blocks in fs */
long f_bavail; /* free blocks avail to non-superuser */
long f_files; /* total file nodes in file system */
long f_ffree; /* free file nodes in fs */
long f_ffree; /* free file nodes in fs */
fsid_t f_fsid; /* file system id */
long f_namelen; /* maximum length of filenames */
long f_spare[6]; /* spare for later */
};
Fields that are undefined for a particular file system are set to 0.
A component of the path prefix of path is not a directory.
path is too long.
The file referred to by path does not exist.
Search permission is denied for a component of the path prefix of path.
Too many symbolic links were encountered in translating path.
Buf or path points to an invalid address.
An I/O error occurred while reading from or writing to the file system.
Insufficient kernel memory was available.
The filesystem path is on does not support statfs.
stime sets the system's idea of the time and date. Time, pointed to by t, is measured in seconds from 00:00:00 GMT January 1, 1970. stime() may only be executed by the super user.
The stpcpy() function copies the string pointed to by src (including the terminating \0 character) to the array pointed to by dest. The strings may not overlap, and the destination string dest must be large enough to receive the copy.
stpcpy() returns a pointer to the end of the string dest (that is, the address of the terminating null character) rather than the beginning.
For example, this program uses stpcpy to concatenate foo and bar to produce foobar, which it then prints.
#include <string.h>
int main (void) { char *to = buffer; to = stpcpy (to, "foo"); to = stpcpy (to, "bar"); printf ("%s\n", buffer); }
The stpncpy function copies at most n characters from the string pointed to by src, including the terminating '\0' character, to the array pointed to by dest. Exactly n characters are written at dest. If the length strlen(src) is smaller than n, the remaining characters in the array pointed to by dest are filled with '\0' characters. If the length strlen(src) is greater or equal to n, the string pointed to by dest will not be '\0' terminated. The strings may not overlap. The programmer must ensure that there is room for at least n characters at dest.
stpncpy returns a pointer to the terminating null in dest, or, if dest is not null-terminated, dest + n.
Reentrant version of strerror. If a temporary buffer is required, at most BUFLEN bytes of BUF will be used.
The strfry() function randomizes the contents of string by using rand(3) to randomly swap characters in the string. The result is an anagram of string.
Return a malloc'd copy of at most n bytes of string. The resultant string is terminated even if no null terminator appears before STRING[N].
The strnlen function returns the number of characters in the string pointed to by s, not including the terminating '\0' character, but at most maxlen. In doing this, strnlen looks only at the first maxlen characters at s and never beyond s+maxlen.
The strnlen function returns strlen(s), if that is less than maxlen, or maxlen if there is no '\0' character among the first maxlen characters pointed to by s.
If *stringp is NULL, the strsep() function returns NULL and does nothing else. Otherwise, this function finds the first token in the string *stringp, where tokens are delimited by symbols in the string delim. This token is terminated with a \0 character (by overwriting the delimiter) and *stringp is updated to point past the token. In case no delimiter was found, the token is taken to be the entire string *stringp, and *stringp is made NULL.
The strsep() function returns a pointer to the token, that is, it returns the original value of *stringp.
The strsep() function was introduced as a replacement for strtok(), since the latter cannot handle empty fields. However, strtok() conforms to ANSI-C and hence is more portable.
This function suffers from the same problems as strtok(). In particular, it modifies the original string. Avoid it.
#define _GNU_SOURCE #include <string.h> char *strsignal(int sig); extern const char * const sys_siglist[]; |
The strsignal() function returns a string describing the signal number passed in the argument sig. The string can only be used until the next call to strsignal().
The array sys_siglist holds the signal description strings indexed by signal number. The strsignal() function should be used if possible instead of this array.
The strsignal() function returns the appropriate description string, or an unknown signal message if the signal number is invalid. On some systems (but not on Linux), a NULL pointer may be returned instead for an invalid signal number.
A token is a nonempty string of characters not occurring in the string delim, followed by \0 or by a character occurring in delim.
The strtok_r() function can be used to parse the string s into tokens. The first call to strtok_r() should have s as its first argument. Subsequent calls should have the first argument set to NULL. Each call returns a pointer to the next token, or NULL when no more tokens are found.
If a token ends with a delimiter, this delimiting character is overwritten with a \0 and a pointer to the next character is saved for the next call to strtok_r(). The delimiter string delim may be different for each call.
ptrptr is a user allocated char* pointer. It must be the same while parsing the same string.
Never use this function. Note that:
It modifies its first argument.
The identity of the delimiting character is lost.
This function cannot be used on constant strings.
The strtok_r() function returns a pointer to the next token, or NULL if there are no more tokens.
#include <sys/types.h> #include <stdlib.h> #include <limits.h> quadt strtoq(const char *nptr, char **endptr, int base); |
The strtoq() function converts the string in nptr to a quadt value. The conversion is done according to the given base, which must be between 2 and 36 inclusive, or be the special value 0.
The string may begin with an arbitrary amount of white space (as determine by isspace(3)) followed by a single optional + or - sign. If base is zero or 16, the string may then include a 0x prefix, and the number will be read in base 16; otherwise, a zero base is taken as 10 (decimal) unless the next character is 0, in which case it is taken as 8 (octal).
The remainder of the string is converted to a long value in the obvious manner, stopping at the first character which is not a valid digit in the given base. (In bases above 10, the letter A in either upper or lower case represents 10, B represents 11, and so forth, with Z representing 35.)
strtoq() function returns the result of the conversion, unless the value would underflow or overflow. If an underflow occurs, strtoq() returns QUAD_MIN. If an overflow occurs, strtoq() returns QUAD_MAX. In both cases, errno is set to ERANGE.
#include <sys/types.h> #include <stdlib.h> #include <limits.h> uquadt strtouq(const char *nptr, char **endptr, int base); |
The strtouq() function converts the string in nptr to a uquadt value. The conversion is done according to the given base, which must be between 2 and 36 inclusive, or be the special value 0.
The string may begin with an arbitrary amount of white space (as determined by isspace(3)) followed by a single optional + or - sign. If base is zero or 16, the string may then include a 0x prefix, and the number will be read in base 16; otherwise, a zero base is taken as 10 (decimal) unless the next character is 0, in which case it is taken as 8 (octal).
The remainder of the string is converted to an unsigned long value in the obvious manner, stopping at the end of the string or at the first character that does not produce a valid digit in the given base. (In bases above 10, the letter A in either upper or lower case represents 10, B represents 11, and so forth, with Z representing 35.)
Upon success the strtouq() function returns either the result of the conversion or, if there was a leading minus sign, the negation of the result of the conversion, unless the original (non-negated) value would overflow. In the case of an overflow the function returns UQUAD_MAX and the global variable errno is set to ERANGE.
system() executes a command specified in string by calling /bin/sh -c string, and returns after the command has been completed. During execution of the command, SIGCHLD will be blocked, and SIGINT and SIGQUIT will be ignored.
The value returned is 127 if the execve() call for /bin/sh fails, -1 if there was another error and the return code of the command otherwise.
If the value of string is NULL, system() returns nonzero if the shell is available, and zero if not.
system() does not affect the wait status of any other children.
The fact that system() ignores interrupts is often not what a program wants. The Single Unix Spec describes some of the consequences - one additional one is that a program which calls system() from a loop can not reliably be interrupted. Many programs will want to use the exec(3) family of functions instead.
Do not use system() from a program with suid or sgid privileges, because strange values for some environment variables might be used to subvert system integrity. Use the exec(3) family of functions instead, but not execlp(3) or execvp(3). system() will not, in fact, work properly from programs with suid or sgid privileges on systems on which /bin/sh is bash version 2, since bash 2 drops privileges on startup. (Debian uses a modified bash which does not do this when invoked as sh.)
The check for the availability of /bin/sh is not actually performed; it is always assumed to be available. ISO C specifies the check, but POSIX.2 specifies that the return shall always be non-zero, since a system without the shell is not conforming, and it is this that is implemented.
It is possible for the shell command to return 127, so that code is not a sure indication that the execve() call failed; check errno to make sure.
Set the current default message catalog to DOMAINNAME.
If DOMAINNAME is null, return the current default.
If DOMAINNAME is "", reset to the default of "messages".

The wait4 function suspends execution of the current process until a child as specified by the pid argument has exited, or until a signal is delivered whose action is to terminate the current process or to call a signal handling function. If a child as requested by pid has already exited by the time of the call (a so-called "zombie" process), the function returns immediately. Any system resources used by the child are freed.
The value of pid can be one of:
wait for any child process whose process group ID is equal to the absolute value of pid.
wait for any child process; this is equivalent to calling wait3.
wait for any child process whose process group ID is equal to that of the calling process.
wait for the child whose process ID is equal to the value of pid.
The value of options is a bitwise OR of zero or more of the following constants:
return immediately if no child is there to be waited for.
return for children which are stopped, and whose status has not been reported.
If status is not NULL, wait4 stores status information in the location pointed to by status.
This status can be evaluated with the following macros (these macros take the stat buffer (an int) as an argument -- not a pointer to the buffer!):
is non-zero if the child exited normally.
evaluates to the least significant eight bits of the return code of the child which terminated, which may have been set as the argument to a call to exit() or as the argument for a return statement in the main program. This macro can only be evaluated if WIFEXITED returned non-zero.
returns true if the child process exited because of a signal which was not caught.
returns the number of the signal that caused the child process to terminate. This macro can only be evaluated if WIFSIGNALED returned non-zero.
returns true if the child process which caused the return is currently stopped; this is only possible if the call was done using WUNTRACED.
returns the number of the signal which caused the child to stop. This macro can only be evaluated if WIFSTOPPED returned non-zero.
If rusage is not NULL, the struct rusage as defined in <sys/resource.h> it points to will be filled with accounting information. See getrusage(2) for details.
The process ID of the child which exited, -1 on error (in particular, when no unwaited-for child processes of the specified kind exist) or zero if WNOHANG was used and no child was available yet. In the latter two cases errno will be set appropriately.
No unwaited-for child process as specified does exist.
If WNOHANG was not set and an unblocked signal or a SIGCHLD was caught. This error is returned by the system call. The library interface is not allowed to return ERESTARTSYS, but will return EINTR.
The warn() function displays a formatted error message on the standard error output. The last component of the program name, a colon character, and a space are output. If the fmt argument is not NULL, the formatted error message, a colon character, and a space are output. The error message string affiliated with the current value of the global variable errno is output. The output is followed by a newline character.
The warnx() function displays a formatted error message on the standard error output. The last component of the program name, a colon character, and a space are output. If the fmt argument is not NULL, the formatted error message, a colon character, and a space are output. The output is followed by a newline character.
The wcpcpy function is the wide-character equivalent of the stpcpy function. It copies the wide character string pointed to by src, including the terminating L'\0' character, to the array pointed to by dest.
The strings may not overlap.
The programmer must ensure that there is room for at least wcslen(src)+1 wide characters at dest.
wcpcpy returns a pointer to the end of the wide-character string dest, that is, a pointer to the terminating L'\0' character.
The wcpncpy function is the wide-character equivalent of the stpncpy function. It copies at most n wide characters from the wide-character string pointed to by src, including the terminating L'\0' character, to the array pointed to by dest. Exactly n wide characters are written at dest. If the length wcslen(src) is smaller than n, the remaining wide characters in the array pointed to by dest are filled with L'\0' characters. If the length wcslen(src) is greater or equal to n, the string pointed to by dest will not be L'\0' terminated.
The strings may not overlap.
The programmer must ensure that there is room for at least n wide characters at dest.
The wcscasecmp function is the wide-character equivalent of the strcasecmp function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2, ignoring case differences (towupper, towlower).
The wcscasecmp function returns zero if the wide-character strings at s1 and s2 are equal except for case distinctions. It returns a positive integer if s1 is greater than s2, ignoring case. It returns a negative integer if s1 is smaller than s2, ignoring case.
The wcsdup function is the wide-character equivalent of the strdup function. It allocates and returns a new wide-character string whose initial contents is a duplicate of the wide-character string pointed to by s.
Memory for the new wide-character string is obtained with malloc(3), and can be freed with free(3).
The wcsdup function returns a pointer to the new wide-character string, or NULL if sufficient memory was not available.
The wcsncasecmp function is the wide-character equivalent of the strncasecmp function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2, but at most n wide characters from each string, ignoring case differences (towupper, towlower).
The wcsncasecmp function returns zero if the wide-character strings at s1 and s2, truncated to at most length n, are equal except for case distinctions. It returns a positive integer if truncated s1 is greater than truncated s2, ignoring case. It returns a negative integer if truncated s1 is smaller than truncated s2, ignoring case.
The wcsnlen function is the wide-character equivalent of the strnlen function. It returns the number of wide-characters in the string pointed to by s, not including the terminating L'\0' character, but at most maxlen. In doing this, wcsnlen looks only at the first maxlen wide-characters at s and never beyond s+maxlen.
The wcsnlen function returns wcslen(s), if that is less than maxlen, or maxlen if there is no L'\0' character among the first maxlen wide characters pointed to by s.

The wcsnrtombs function is like the wcsrtombs function, except that the number of wide characters to be converted, starting at *src, is limited to nwc.
If dest is not a NULL pointer, the wcsnrtombs function converts at most nwc wide characters from the wide-character string *src to a multibyte string starting at dest. At most len bytes are written to dest. The state *ps is updated. The conversion is effectively performed by repeatedly calling wcrtomb(dest,*src,ps), as long as this call succeeds, and then incrementing dest by the number of bytes written and *src by one. The conversion can stop for three reasons:
1. A wide character has been encountered that can not be represented as a multibyte sequence (according to the current locale). In this case *src is left pointing to the invalid wide character, (size_t)(-1) is returned, and errno is set to EILSEQ.
2. nwc wide characters have been converted without encountering a L'\0', or the length limit forces a stop. In this case *src is left pointing to the next wide character to be converted, and the number of bytes written to dest is returned.
3. The wide-character string has been completely converted, including the terminating L'\0' (which has the side effect of bringing back *ps to the initial state). In this case *src is set to NULL, and the number of bytes written to dest, excluding the terminating '\0' byte, is returned.
If dest is NULL, len is ignored, and the conversion proceeds as above, except that the converted bytes are not written out to memory, and that no destination length limit exists.
In both of the above cases, if ps is a NULL pointer, a static anonymous state only known to the wcsnrtombs function is used instead.
The programmer must ensure that there is room for at least len bytes at dest.
The wcsnrtombs function returns the number of bytes that make up the converted part of multibyte sequence, not including the terminating null byte. If a wide character was encountered which could not be converted, (size_t)(-1) is returned, and errno set to EILSEQ.
The behavior of wcsnrtombs depends on the LC_CTYPE category of the current locale.
Passing NULL as ps is not multi-thread safe.

LSB systems support POSIX threads with the following exceptions. This list is intended to match the behavior of historical Linux implementations. Applications should be written to deal with either POSIX threads or the thread behaviors described here.
POSIX specifies a concept of per-process rather than per-thread signals. The LSB does not require this behavior; traditional Linux implementations have had per-thread signals only. A related issue is that applications cannot rely on getpid() returning the same value in different threads.
Note: one implication of per-thread signals is that a core dump (for example) may not stop all threads in a given process. This may be an issue when designing ways to stop/start applications.
Applications which create child processes (using fork() and the like) must then wait for them (using waitpid() family of functions) in the same thread as they created them. Note that coding applications this way will work both with full POSIX threads and legacy Linux thread implementations.
POSIX specifies that changing the user or group id instantly affects the behavior of all threads. This behavior is not specified; applications must use their own lock if they need this behavior. Rationale: it seems unnecessary and it is a performance hit (an SMP kernel must lock the user id).
Although this standard doesn't have a way to list processes (/proc or "ps" command line isn't in, right?), it is our intention to not specify one way or the other whether multiple threads appear as separate processes or as a single process.
Applications cannot rely on resource limits (getrusage and setrusage) being maintained per-process rather than per-thread.
Applications must disconnect from the controlling tty before calling pthread_create.
times() doesn't account for all threads, just the caller.
Applications must not call pthread_cancel if they call any system libraries (most notably X Window System libraries), as system libraries are not guaranteed to be thread safe. Likewise, for such libraries, only one thread per process may call them.
Applications cannot rely on fcntl/lockf locks being visible per-process rather than per-thread. Likewise for mandatory file locks.
Threaded applications cannot use SIGUSR1 or SIGUSR2.
The behavior of the interfaces in this library is specified by the following standards.

This function implements the System V dynamic linking routines.
The dladdr() function is the inverse of the dlsym() function. If the given address is successfully located inside a module, dladdr() returns nonzero, otherwise 0. On a successful return, the fields of dlip are filled in as follows:
the pathname of the module
the base address of the module
the name of the highest addressed symbol whose address precedes the given address

Shared objects must be linked using the -shared option to the linker ld(1). The linker flag -rpath may be used to add a directory to the default search path for shared objects and shared libraries. The linker flag -E or the C compiler flag -rdynamic should be used to cause the application to export its symbols to the shared objects.

The behavior of the interfaces in this library is specified by the following standards.
| Linux Standard Base[22] |
The forkpty() function joins openpty(), fork(), and login_tty() to create a new process operating on a pseudo-tty. The file descriptor of the master side of the pseudo-tty is returned in amaster, and null or the filename of the slave in name. If non-null, the termp and winp parameters will determine the terminal attributes and window size of the slave side of the pseudo-tty.
On success of the child process, zero is returned. When the parent process receives the PID of its child process, pid is returned. On error, -1 is returned, and errno is set appropriately.
The login() function updates the /var/run/utmp and /var/log/wtmp files with user information contained in ut.
login_tty() sets up for a login on the tty referenced by the file descriptor fdr. This function creates a new session, makes the tty for the current process the controlling terminal, sets the standard input, output, and error streams of the current process, and closes fdr.
Given the device line, the logout() function removes the entry from the corresponding /var/run/utmp system file.
Zero is returned if there was no entry to remove. A non-zero return value indicates success.
logwtmp() constructs an utmp structure using line, name, host, current time and current process id. Then it calls updwtmp() to append the structure to the utmp file.
Both functions are available under glibc2, but not under libc5. However, logwtmp occurs in the old libbsd.
int openpty(int *amaster, int *aslave, char *name, struct termios *termp, struct winsize *winp); |
The openpty() function finds an available pseudo-tty and returns file descriptors for the amaster and aslave. The filename of the slave is returned in name, otherwise a null. The terminal parameters of the slave will be set to the values in termp, otherwise a null. The window size of the slave will be set to the values in winp, otherwise a null.
The X Libraries should be built thread-safe.

Applications should be provided in the RPM packaging format as defined in the appendix of Maximum RPM, with some restrictions listed below. [35]
Distributions must provide a mechanism for installing applications in this packaging format with some restrictions listed below. [36]
Scripts used as part of the package install and uninstall may only use commands and interfaces that are specified by the LSB. All other commands are not guaranteed to be present, or to behave in expected ways.
Packages may not use RPM triggers.
Packages may not depend on the order in which scripts are executed (pre-install, pre-uninstall, &c), when doing an upgrade.
The LSB does not specify the interface to the tools used to manipulate LSB-conformant packages. Each conforming distribution will provide documentation for installing LSB packages.
Because there is no consistent packaging naming among the various Linux distributions, it is necessary for LSB-conformant packages to adhere the following naming rules to avoid conflicts with packages provided by the distributions.
All LSB package names must begin with the prefix "lsb-" to avoid conflicting with existing packages used by Linux distributions.
If the package name contains only one hyphen (including the one in the "lsb-" prefix) then the package name must be assigned by the Linux Assigned Names and Numbers Authority (LANANA), which shall maintain a registry of LSB names.
If the package name contains more than one hyphen (i.e., "lsb-www.redhat.com-redhat-database", "lsb-gnome-gnumeric"), then the portion of the package name between first and second hyphens must either be an LSB provider name assigned by the LANANA, or it may be one of the owners' fully-qualified domain name in lower case (e.g., "debian.org", "staroffice.sun.com"). The LSB provider name assigned by LANANA must only consist of the ASCII characters [a-z0-9].
Packages must depend on a dependency "lsb". They may not depend on other system-provided dependencies. If a package includes "Provides" it must only provide a virtual package name which is registered to that application.
The following table lists the Commands and Utilities. Unless otherwise specified the command or utility is described in the Single UNIX Specification (SUS). When an interface is not defined in the SUS, then the next prevailing standard is referenced (ie., POSIX, SVID).
The behavior of the interfaces described in this section are specified by the following standards.

This section contains descriptions for commands and utilities whose specified behavior in the LSB contradicts or extends the standards referenced. It also contains commands and utilities only required by the LSB and not specified by other standards.
need not be accepted.
has implementation-dependent behavior.
has implementation-dependent behavior; using -r is suggested.
cats the jobs listed on the command line to standard output.
is functionally equivalent to the -r option specified in the SUS.
is not supported, but the '-d' option is equivalent.
is not supported.
prints the version number to standard error.
shows the time the job will be executed.
awk is as specified in the SUS with no differences. gawk and mawk are SUS-compliant implementations of the awk language.
batch reads commands from standard input or a specified file which are to be executed at a later time, using /bin/sh.
reads the job from file rather than standard input.
sends mail to the user when the job has completed even if there was no output.
uses the specified queue. A queue designation consists of a single letter; valid queue designations range from a to z. and A to Z. The a queue is the default for at and the b queue for batch. Queues with higher letters run with increased niceness. The special queue "=" is reserved for jobs which are currently running.
prints the version number to standard error.
shows the time the job will be executed.
does not print the normal welcome message.
processes exactly the POSIX bc language.
prints the version number and copyright and quits.
gives warnings for extensions to POSIX bc.
is equivalent to -vET.
numbers nonblank output lines.
is equivalent to -vE.
displays $ at end of each line.
numbers all output lines.
displays never more than one single blank line.
is equivalent to -vT.
displays TAB characters as ^I.
has implementation-dependent behavior.
uses ^ and M- notation, except for LFD and TAB.
outputs version information and exits.
chfn changes user fullname, office number, office extension, and home phone number information for a user's account. This information is typically printed by finger and similar programs. A normal user may only change the fields for their own account, the super user may change the fields for any account. Also, only the super user may use the -o option to change the undefined portions of the GCOS field.
The only restrictions placed on the contents of the fields is that no control characters may be present, nor any of comma, colon, or equal sign. The other field does not have this restriction, and is used to store accounting information used by other applications.
If none of the options are selected, chfn operates in an interactive fashion. The prompts and expected input in interactive mode are implementation-dependent and should not be relied upon.
As it is possible for the system to be configured to restrict which fields a non-privileged user is permitted to change, applications should be written to gracefully handle these situations.
sets the user's full name.
sets the user's room number.
sets the user's work phone number.
sets the user's home phone number.
sets the contents of the other field.
is like verbose, but reports only when a change is made.
affects the referent of each symbolic link, rather than the symbolic link itself.
affects symbolic links instead of any referenced file. (Available only on systems that can change the ownership of a symlink.)
suppresses most error messages.
uses RFILE's group rather than the specified GROUP value.
outputs a diagnostic for every file processed.
outputs version information and exit.
chmod [OPTION]... MODE[,MODE]... FILE... chmod [OPTION]... OCTAL-MODE FILE... chmod [OPTION]... --reference=RFILE FILE... |
is like verbose, but reports only when a change is made.
suppresses most error messages.
uses RFILE's mode instead of MODE values.
outputs a diagnostic for every file processed.
outputs version information and exits.
chown [OPTION]... OWNER[:[GROUP]] FILE... chown [OPTION]... :GROUP FILE... chown [OPTION]... --reference=RFILE FILE... |
is like verbose, but reports only when a change is made.
affects the referent of each symbolic link, rather than the symbolic link itself.
affects symbolic links instead of any referenced file. (Available only on systems that can change the ownership of a symlink.)
changes the owner and/or group of each file only if its current owner and/or group match those specified here. Either may be omitted, in which case a match is not required for the omitted attribute.
suppresses most error messages.
uses RFILE's owner and group rather than the specified OWNER:GROUP values.
outputs a diagnostic for every file processed.
outputs version information and exits.
The use of the '.' character as a separator between the specification of the user name and group name is supported (in addition to the use of the ':' character as specified in the SUS).
chsh changes the user login shell. This determines the name of the user's initial login command. A normal user may only change the login shell for their own account, the super user may change the login shell for any account.
The only restrictions placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the super-user, and then any value may be added. An account with a restricted login shell may not change their login shell.
If the -s option is not selected, chsh operates in an interactive mode. The prompts and expected input in this mode are implementation-defined.
is the same as -dpR.
makes a backup of each existing destination file.
is like --backup but does not accept an argument.
never follows symbolic links.
follows command-line symbolic links.
links files instead of copying.
always follows symbolic links.
appends source path to DIRECTORY.
removes each existing destination file before attempting to open it. (Contrast with --force.)
controls creation of sparse files.
By default, sparse SOURCE files are detected by a crude heuristic and the corresponding DEST file is made sparse as well. That is the behavior selected by --sparse=auto. Specify --sparse=always to create a sparse DEST file whenever the SOURCE file contains a long enough sequence of zero bytes. Use --sparse=never to inhibit creation of sparse files.
removes any trailing slashes from each SOURCE argument.
makes symbolic links instead of copying.
overrides the usual backup suffix.
moves all SOURCE arguments into DIRECTORY.
copies only when the SOURCE file is newer than the destination file or when the destination file is missing.
explains what is being done.
stays on this file system.
outputs version information and exits.
cpio is as specified in the SUS. While additional features may be found in Linux versions of this command, the SUS-specified interface is correctly and completely implemented.
uses sprintf FORMAT instead of %d.
are equivalent to the -s option as specified in the SUS.
removes empty output files.
outputs version information and exit.
specifies the name of the user whose crontab is to be used, rather than the user who is running crontab.
displays time described by STRING, not now.
is like --date once for each line of DATEFILE.
displays the last modification time of FILE.
outputs RFC2822-compliant date string.
sets time described by STRING.
is equivalent to the -u option as specified in the SUS.
outputs version information and exits.
is a keyword to the CONV= option causing alternate bytes to be swapped. The treatment of the odd character is implementation-dependent.
df is as specified in the SUS but with the variations listed in the Differences section below, and as follows.
Disk space is shown in 1K blocks by default, unless the environment variable POSIXLY_CORRECT is set, in which case 512-byte blocks are used.
If an argument is the absolute file name of a disk device node containing a mounted filesystem, df shows the space available on that filesystem rather than on the filesystem containing the device node (which is always the root filesystem).
includes filesystems having 0 blocks.
uses SIZE-byte blocks.
prints sizes in human-readable format (e.g., 1K, 234M, 2G).
prints sizes in human-readable format, but uses powers of 1000 (not 1024).
lists inode information instead of block usage.
limits listing to local filesystems.
is like --block-size=1048576
does not invoke sync before getting usage info. (default)
uses the POSIX output format.
invokes sync before getting usage info.
has implementation-dependent behavior.
is same as -P as specified in the SUS.
invokes sync before getting usage info.
limits listing to filesystems of type TYPE. (Different from behavior as specified in the SUS.)
prints filesystem type.
limits listing to filesystems not of type TYPE.
treats all files as text and compares them line-by-line, even if they do not seem to be text.
ignores changes that just insert or delete blank lines.
reports only whether the files differ, not the details of the differences.
is equivalent to -C as specified in the SUS.
changes the algorithm to perhaps find a smaller set of changes; this makes diff slower (sometimes much slower).
makes merged if-then-else format output conditional on the preprocessor macro name.
is equivalent to -e as specified in the SUS.
when comparing directories, ignores files and subdirectories whose basenames match pattern.
when comparing directories, ignores files and subdirectories whose basenames match any pattern contained in file.
expands tabs to spaces in the output to preserve the alignment of tabs in the input files.
in context and unified format, shows some of the last preceding line that matches regexp for each hunk of differences.
makes output that looks vaguely like an ed script, but has changes in the order they appear in the file.
uses heuristics to speed handling of large files that have numerous scattered small changes.
does not discard the last lines lines of the common prefix and the first lines lines of the common suffix.
ignores changes in case; considers upper and lower case letters equivalent.
ignores changes that just insert or delete lines that match regexp.
makes merged if-then-else format output conditional on the preprocessor macro name.
ignores white space when comparing lines.
ignores changes in case; considers upper and lower case to be the same.
ignores changes that just insert or delete lines that match regexp.
ignores changes in amount of white space.
outputs a tab rather than a space before the text of a line in normal or context format. This causes the alignment of tabs in the line to look normal.
passes the output through pr to paginate it.
ignores changes in case; considers upper and lower case to be the same.
clears the ring buffer contents after printing.
sets the level at which logging of messages is done to the console.
uses a buffer of bufsize to query the kernel ring buffer. This is 8196 by default (this matches the default kernel syslog buffer size in 2.0.33 and 2.1.103). If you have set the kernel buffer to larger than the default then this option can be used to view the entire buffer.
uses SIZE-byte blocks.
prints size in bytes.
produces a grand total.
dereferences PATHs when symbolic link.
prints sizes in human-readable format (e.g., 1K, 234M, 2G).
is equivalent to --block-size=1024.
counts sizes many times if hard-linked.
dereferences all symbolic links.
is equivalent to --block-size=1048576.
has implementation-dependent behavior.
does not include size of subdirectories.
excludes files that match any pattern in FILE.
excludes files that match PAT.
prints the total for a directory (or file, with --all) only if it is N or fewer levels below the command line argument; --max-depth=0 is the same as --summarize.
outputs version information and exits.
Unlike the behavior specified in the SUS, echo does support options. Behavioral differences are listed below.
does not output the trailing newline.
enables interpretation of specific backslash-escaped characters.
disables interpretation of those sequences in STRINGs.
outputs version information and exits; should be alone.
is equivalent to -i.
removes variable from the environment.
does not convert TABs after non-whitespace.
supplements behavior as specified in the SUS by allowing argument to specify the number of characters-apart tabs are (instead of 8).
is same as STRING : REGEXP.
is substring of STRING, POS counted from 1.
is index in STRING where any CHARS is found, or 0.
is length of STRING.
interprets TOKEN as a string, even if it is a keyword like match or an operator like /.
does not prepend filenames to output lines.
causes a checking printout of the parsed form of the magic file. This is usually used in conjunction with -m to debug a new magic file before installing it.
reads the names of the files to be examined from namefile (one per line) before the argument list. Either namefile or at least one filename argument must be present; to test the standard input, use `-' as a filename argument.
causes the file command to output mime type strings rather than the more traditional human-readable ones. Thus, it may say `text/plain; charset=us-ascii' rather than `ASCII text'. In order for this option to work, file changes the way it handles files recognized by the command itself (such as many of the text file types, directories, etc.), and makes use of an alternative `magic' file.
does not stop at the first match, keeps going.
specifies an alternate list of files containing magic numbers. This can be a single file, or a colon-separated list of files.
forces stdout to be flushed after checking each file. This is only useful if checking a list of files. It is intended to be used by programs that want filetype output from a pipe.
tries to look inside compressed files.
causes symlinks to be followed.
causes block or character special files (that are potentially problematic when processed by file) to be read in addition to the argument files ordinarily identified by stat(2). This is useful for determining the filesystem types of the data in raw disk partitions, which are block special files. This option also causes file to disregard the file size as reported by stat(2) since on some systems it reports a zero size for raw disk partitions.
measures times (for -amin, -atime, -cmin, -ctime, -mmin, and -mtime) from the beginning of today rather than from 24 hours ago.
dereferences symbolic links. Implies -noleaf.
descends at most levels (a non-negative integer) levels of directories below the command line arguments. -maxdepth 0 means only apply the tests and actions to the command line arguments.
applies no tests or actions at levels less than levels (a non-negative integer). -mindepth 1 means process all files except the command line arguments.
is equivalent to -xdev as specified in the SUS.
does not optimize by assuming that directories contain 2 fewer subdirectories than their hard link count.
prints the find version number and exits.
displays files last accessed n minutes ago.
displays files last accessed more recently than file was modified. -anewer is affected by -follow only if -follow comes before -anewer on the command line.
displays files with status last changed n minutes ago.
displays files with status last changed more recently than file was modified. -cnewer is affected by -follow only if -follow comes before -cnewer on the command line.
displays files that are empty and are either regular or directory files.
is always false.
displays files on a filesystem of type type.
displays files with numeric group ID of n.
is like -lname, but the match is case-insensitive.
is like -name, but the match is case-insensitive.
displays files with inode number of n.
is like -path, but the match is case-insensitive.
is like -regex, but the match is case-insensitive.
displays files that are symbolic links whose contents match shell pattern pattern. The metacharacters do not treat / or . specially.
displays files with data last modified n minutes ago.
displays files with numeric user ID corresponding to no user.
displays files with numeric group ID corresponding to no group.
displays files with name matching shell pattern pattern.
displays files with any of the permission bits mode set.
displays files with names matching regular expression pattern. This is a match on the whole path, not a search.
is always true.
supplements types as specified in the SUS with the letters l and s (symbolic links and sockets, respectively).
displays files with numeric user ID of n.
displays files last accessed n days after status was last changed.
is equivalent to -type unless the file is a symbolic link. For symbolic links: if -follow has not been given, true if the file is a link to a file of type c; if -follow has been given, true if c is l. In other words, for symbolic links, -xtype checks the type of the file that -type does not check.
is true. Is like -ls but write to file like -fprint.
is true. Prints the full file name into file file. If file does not exist when find is run, it is created; if it does exist, it is truncated. The file names `/dev/stdout' and `/dev/stderr' are handled specially; they refer to the standard output and standard error output, respectively.
is true. Is like -print0 but write to file like -fprint.
is true. Like -printf but write to file like -fprint.
is true. Prints the full file name on the standard output, followed by a null character. This allows file names that contain newlines to be correctly interpreted by programs that process the find output.
is true. Prints format on the standard output, interpreting \ escapes and % directives. Field widths and precisions can be specified as with the printf C function. Unlike -print, -printf does not add a newline at the end of the string. The escapes and directives are:
alarm bell.
backspace.
stops printing from this format immediately and flushes the output.
form feed.
newline.
carriage return.
horizontal tab.
vertical tab.
literal backslash (\).
literal percent sign.
last file access time in the format returned by the C ctime function.
last file access time in the format specified by k, which is either @ or a directive for the C strftime function. The possible values for k are listed below; some of them might not be available on all systems, due to differences in strftime between systems.

has implementation-dependent behavior.
kills processes accessing the file. Unless changed with -signal, SIGKILL is sent. An fuser process never kills itself, but may kill other fuser processes. The effective user ID of the process executing fuser is set to its real user ID before attempting to kill.
asks the user for confirmation before killing a process. This option is silently ignored if -k is not present too.
lists all known signal names.
name specifies a file on a mounted file system or a block device that is mounted. All processes accessing files on that file system are listed. If a directory file is specified, it is automatically changed to name/. to use any file system that might be mounted on that directory.
selects a different name space. The name spaces file (file names, the default), udp (local UDP ports), and tcp (local TCP ports) are supported. For ports, either the port number or the symbolic name can be specified. If there is no ambiguity, the shortcut notation name/space (e.g. name/proto) can be used.
operates silently. -u and -v are ignored in this mode. -a must not be used with -s.
uses the specified signal instead of SIGKILL when killing processes. Signals can be specified either by name (e.g. -HUP) or by number (e.g. -1).
verbose mode.
displays version information.
resets all options and set the signal back to SIGKILL.
creates C header file NAME containing symbol definitions.
does not use existing catalog, forces new output file.
writes output to file NAME.
prints NUM lines of trailing context after matching lines.
processes a binary file as if it were text; this is equivalent to the --binary-files=text option.
prints NUM lines of leading context before matching lines.
prints NUM lines (default 2) of output context.
prints the byte offset within the input file before each line of output.
assumes that the file is of type TYPE if its first few bytes indicate it contains binary data. By default, TYPE is binary, and grep normally outputs either a one-line message saying that a binary file matches, or no message if there is no match. If TYPE is without-match, grep assumes that a binary file does not match; this is equivalent to the -I option. If TYPE is text, grep processes a binary file as if it were text; this is equivalent to the -a option. Warning: grep --binary-files=text might output binary garbage, which can have nasty side effects if the output is a terminal and if the terminal driver interprets some of it as commands.
suppresses normal output; instead, prints a count of matching lines for each input file. With the -v, --invert-match option (see below), counts non-matching lines.
processes the input file as a directory with ACTION. By default, ACTION is read, which means that directories are read just as if they were ordinary files. If ACTION is skip, directories are silently skipped. If ACTION is recurse, grep reads all files under each directory, recursively; this is equivalent to the -r option.
interprets PATTERN as a basic regular expression. (default)
prints the filename for each match.
suppresses the prefixing of filenames on output when multiple files are searched.
processes a binary file as if it did not contain matching data; this is equivalent to the --binary-files=without-match option.
equivalent to -i.
suppresses normal output; instead, prints the name of each input file from which no output would normally have been printed. The scanning will stop on the first match.
equivalent to -l.
uses the mmap(2) system call to read input, if possible, instead of the default read(2) system call. In some situations, --mmap yields better performance. However, --mmap can cause undefined behavior (including core dumps) if an input file shrinks while grep is operating, or if an I/O error occurs.
equivalent to -n.
equivalent to -q.
reads all files under each directory, recursively; this is equivalent to the -d recurse option.
equivalent to -s.
prints the version number of grep to standard error.
equivalent to -v.
selects only those lines containing matches that form whole words. The test is that the matching substring must either be at the beginning of the line, or preceded by a non-word constituent character. Similarly, it must be either at the end of the line or followed by a non-word constituent character. Word-constituent characters are letters, digits, and the underscore.
equivalent to -x.
outputs a zero byte (the ASCII NUL character) instead of the character that normally follows a file name.
specifies the numerical value of the group's ID. This value must be unique, unless the -o option is used. The value must be non-negative.
groupdel modifies the system account files, deleting all entries that refer to group. The named group must exist.
specifies the numerical value of the group's ID. This value must be unique, unless the -o option is used. The value must be non-negative. Any files which the old group ID is the file group ID must have the file group ID changed manually.
changes the name of the group from group to group_name.
groups displays the current group ID names or values. If the value does not have a corresponding entry in /etc/group, the value will be displayed as the numerical group value. The optional user parameter will display the groups for the named user.
gzip reduces the size of the named files using Lempel-Ziv coding (LZ77). Whenever possible, each file is replaced by one with the extension .gz, while keeping the same ownership modes, access and modification times. If no files are specified, or if a file name is "-", the standard input is compressed to the standard output. gzip will only attempt to compress regular files. In particular, it will ignore symbolic links.
does nothing on Linux systems.
writes output on standard output; keeps original files unchanged. If there are several input files, the output consists of a sequence of independently compressed members. To obtain better compression, concatenate all input files before compressing them.
decompresses.
forces compression or decompression even if the file has multiple links or the corresponding file already exists, or if the compressed data is read from or written to a terminal. If the input data is not in a format recognized by gzip, and if the option --stdout is also given, copy the input data without change to the standard ouput: let zcat behave as cat. If -f is not given, and when not running in the background, gzip prompts to verify whether an existing file should be overwritten.
lists the compressed size, uncompressed size, ration and uncompressed name for each compressed file. Gives the uncompressed size as -1 for files not in gzip format. Additionally displays method, crc and timestamp for the uncompress file when used in combination with --verbose.
The compression methods currently supported are deflate, compress, lzh (SCO compress -H) and pack. The crc is given as ffffffff for a file not in gzip format.
With --name, the uncompressed name, date and time are those stored within the compress file, if present.
With --verbose, the size totals and compression ratio for all files is also displayed, unless some sizes are unknown. With --quiet, the title and totals lines are not displayed.
displays the gzip license and quit.
does not save the original file name and time stamp by default when compressing. (The original name is always saved if the name had to be truncated.) When decompressing, do not restore the original file name if present (remove only the gzip suffix from the compressed file name) and do not restore the original time stamp if present (copy it from the compressed file). This option is the default when decompressing.
always saves the original file name and time stamp when compressing; this is the default. When decompressing, restore the original file name and time stamp if present. This option is useful on systems which have a limit on file name length or when the time stamp has been lost after a file transfer.
suppresses all warnings.
travels the directory structure recursively. If any of the file names specified on the command line are directories, gzip will descend into the directory and compress all the files it finds there (or decompress them in the case of gunzip).
uses suffix .suf instead of .gz.
checks the compressed file integrity.
displays the name and percentage reduction for each file compressed or decompressed.
displays the version number and compilation options, then quits.
regulates the speed of compression using the specified digit #, where -1 or --fast indicates the fastest compression method (less compression) and -9 or --best indicates the slowest compression method (best compression). The default compression level is -6 (that is, biased towards high compression at expense of speed).
prints first SIZE bytes. SIZE may have a multiplier suffix: b for 512, k for 1K, m for 1 Meg.
is equivalent to -n.
does not print headers giving file names.
prints headers giving file names.
hostname [-v] [-a] [--alias] [-d] [--domain] [-f] [--fqdn] [-i] [--ip-address] [--long] [-s] [--short] [-y] [--yp] [--nis] hostname [-v] [-F filename] [--file filename] [hostname] hostname [-v] [-h] [--help] [-V] [--version] |
hostname is used to either set or display the current host or domain name of the system. This name is used by many of the networking programs to identify the machine. The domain name is also used by NIS/YP.
When called without any arguments, the program displays the name of the system as returned by the gethostname(2) function.
When called with one argument or with the --file option, the commands set the host name or the NIS/YP domain name. Note, that only the super-user can change the names.
displays the alias name of the host (if used).
displays the name of the DNS domain.
reads the host name from the specified file. Comments (lines starting with a #) are ignored.
displays the FQDN (Fully Qualified Domain Name).
displays the IP address(es) of the host.
displays the short host name. This is the host name cut at the first dot.
prints version information on standard output and exits successfully.
tells what's going on.
displays the NIS domain name. If a parameter is given (or --file name) then root can also set a new NIS domain.
iconv converts the encoding of characters in inputfile from one coded character set to another. The result is written to standard output unless otherwise specified by the --output option.
converts characters from encoding.
converts characters to encoding.
lists known coded character sets.
specifies output file (instead of stdin).
prints progress information.
install [OPTION]... SOURCE DEST (1st format) install [OPTION]... SOURCE... DIRECTORY (2nd format) install -d [OPTION]... DIRECTORY... (3rd format) |
In the first two formats, copy SOURCE to DEST or multiple SOURCE(s) to the existing DIRECTORY, while setting permission modes and owner/group. In the third format, create all components of the given DIRECTORY(ies).
makes a backup of each existing destination file.
is like --backup, but does not accept an argument.
treats all arguments as directory names; creates all components of the specified directories.
creates all leading components of DEST except the last, then copies SOURCE to DEST; useful in the 1st format.
sets group ownership, instead of process' current group.
sets permission mode (as in chmod), instead of rwxr-xr-x.
sets ownership (super-user only).
applies access/modification times of SOURCE files to corresponding destination files.
strips symbol tables, only for 1st and 2nd formats.
overrides the usual backup suffix.
prints the name of each directory as it is created.
ipcs provides information on the ipc facilities for which the calling process has read access.
The -i option allows a specific resource id to be specified. Only information on this id will be printed.
shared memory segments.
message queues.
semaphore arrays.
all. (default)
killall sends a signal to all processes running any of the specified commands. If no signal name is specified, SIGTERM is sent.
Signals can be specified either by name (e.g. -HUP) or by number (e.g. -1). Signal 0 (check if a process exists) can only be specified by number.
If the command name contains a slash (/), processes executing that particular file will be selected for killing, independent of their name.
killall returns a non-zero return code if no process has been killed for any of the listed commands. If at least one process has been killed for each command, killall returns zero.
A killall process never kills itself (but may kill other killall processes).
requires an exact match for very long names. If a command name is longer than 15 characters, the full name may be unavailable (i.e. it is swapped out). In this case, killall will kill everything that matches within the first 15 characters. With -e, such entries are skipped. killall prints a message for each skipped entry if -v is specified in addition to -e.
kills the process group to which the process belongs. The kill signal is only sent once per group, even if multiple processes belonging to the same process group were found.
asks interactively for confirmation before killing.
lists all known signal names.
does not complain if no processes were killed.
reports if the signal was successfully sent.
displays version information.
makes a backup of each existing destination file.
treats destination that is a symlink to a directory as if it were a normal file.
prompts whether to remove destinations.
makes symbolic links instead of hard links.
overrides the usual backup suffix.
moves all SOURCE arguments into directory DIR.
prints name of each file before linking.
outputs version information and exits.
The backup suffix is ~, unless set with --suffix or SIMPLE_BACKUP_SUFFIX. The version control method may be selected via the --backup option or through the VERSION_CONTROL environment variable. Here are the values:
never makes backups (even if --backup is given).
makes numbered backups.
numbered if numbered backups exist, simple otherwise
always makes simple backups.
is equivalent to -f.
is equivalent to -i.
is equivalent to -c.
generates extra warnings about errors that are normally ignored.
suppresses all notifications and warnings, and reports only fatal errors.
login is used to establish a new session with the system. It is normally invoked automatically by responding to the login: prompt on the user's terminal. login may be special to the shell and may not be invoked as a sub-process. Typically, login is treated by the shell as exec login which causes the user to exit from the current shell. Attempting to execute login from any shell but the login shell will produce an error message.
When invoked from the login: prompt, the user may enter environmental variables after the username. These variables are entered in the form NAME=VALUE. Not all variables may be set in the fashion, notably PATH, HOME and SHELL. Additionally, IFS may be inhibited if the user's login shell is /bin/sh.
preserves environment.
does not perform authentication, user is preauthenticated.
specifies the name of the remote host for this login.
performs autologin protocol for rlogin.
lpr uses a spooling daemon to print the named files when facilities become available. If no names appear, the standard input is assumed.
identifies binary data that is not to be filtered but sent as raw input to printer.
formats with "pr" before sending to printer.
sends output to the printer named printer instead of the default printer.
suppresses header page.
uses symbolic links.
specifies copies as the number of copies to print.
specifies name as the job name for the header page.
specifies title as the title used for "pr".
displays the *, @, and | characters for executables, links, and FIFOs, respectively (in addition to the slash declared by the SUS).
The lsb_release command prints certain LSB (Linux Standard Base) and Distribution information.
With no option, same as -v.
displays version of LSB against which distribution is compliant.
displays string id of distributor.
displays single line text description of distribution.
displays release number of distribution.
displays codename according to distribution release.
displays all of the above information.
displays all of the above information in short output format.
displays a human-readable help message.
outputs version information and exits.
unbuffers output, ignores interrupts.
stops execution after first warning.
suppresses some warnings for builtins.
forces a m4_ prefix to all builtins.
searches this directory second for includes.
is equivalent to -D.
deletes builtin NAME.
is equivalent to -s.
suppresses all GNU extensions.
sets symbol lookup hash table size.
changes artificial nesting limit.
produces a frozen state on FILE at end.
reloads a frozen state from FILE at start.
sets debug level (no FLAGS implies 'aeq'). FLAGS is any of:
traces for all macro calls, not only 'ed.
shows actual arguments.
shows expansion.
quotes values as necessary, with a or e flag.
shows before collect, after collect and after call.
adds a unique macro call id, useful with c flag.
says current input file name.
says current input line number.
shows results of path searches.
shows changes in input files.
is shorthand for all of the above flags.
traces NAME when it will be defined.
restricts macro tracing size.
redirects debug and traces output.
make is as specified in the SUS but with differences as listed below. The GNU make command contains syntax extensions beyond those specified in the SUS.
changes to directory dir before reading the makefiles or doing anything else. If multiple -C options are specified, each is interpreted relative to the previous one: -C / -C etc is equivalent to -C /etc. This is typically used with recursive invocations of make.
prints debugging information in addition to normal processing. The debugging information says which files are being considered for remaking, which filetimes are being compared and with what results, which files actually need to be remade, which implicit rules are considered and which are applied---everything interesting about how make decides what to do.
specifies a directory dir to search for included makefiles. If several -I options are used to specify several directories, the directories are searched in the order specified. Unlike the arguments to other flags of make, directories given with -I flags may come directly after the flag: -Idir is allowed, as well as -I dir. This syntax is allowed for compatibility with the C preprocessor's -I flag.
specifies the number of jobs (commands) to run simultaneously. If there is more than one -j option, the last one is effective. If the -j option is given without an argument, make will not limit the number of jobs that can run simultaneously.
specifies that no new jobs (commands) should be started if there are others jobs running and the load average is at least load (a floating-point number). With no argument, removes a previous load limit.
does not remake the file file even if it is older than its dependencies, and do not remake anything on account of changes in file. Essentially the file is treated as very old and its rules are ignored.
prints the version of the make program plus a copyright, a list of authors and a notice that there is no warranty.
prints a message containing the working directory before and after other processing. This may be use ful for tracking down errors from complicated nests of recursive make commands.
pretends that the target file has just been modified. When used with the -n flag, this shows you what would happen if you were to modify that file. Without -n, it is almost the same as running a touch command on the given file before running make, except that the modification time is changed only in the imagination of make.
man is as specified in the SUS. While additional features my be found in Linux versions of this command, the SUS specified interface is correctly and completely implemented.
uses binary mode.
checks md5sum of all files listed in file against the checksum listed in the same file. The actual format of that file is the same as output of md5sum. That is, each line in the file describes a file.
prints a message for each created directory.
outputs version information and exits.
Create the special file NAME of the given TYPE.
MAJOR MINOR are forbidden for TYPE p, mandatory otherwise. TYPE may be:
creates a block (buffered) special file.
creates a character (unbuffered) special file.
creates a FIFO.
sets permission mode (as in chmod), not a=rw - umask.
outputs version information and exits.
mktemp takes the given file name template and overwrites a portion of it to create a file name. This file name is unique and suitable for use by the application.
fails silently if an error occurs. This is useful if a script does not want error output to go to standard error.
operates in `unsafe' mode. The temp file will be unlinked before mktemp exits. This is slightly better than mktemp(3) but still introduces a race condition. Use of this option is not encouraged.
specifies an integer which is the screen size (in lines).
prompts user with the message "[Press space to continue, 'q' to quit.]" and will display "[Press 'h' for instructions.]" instead of ringing the bell when an illegal key is pressed.
has implementation-dependent behavior.
prevents the typical behavior where more treats ^L (form feed) as a special character and pauses after any line that contains a form feed.
has implementation-dependent behavior.
counts logical, rather than screen lines (i.e., long lines are not folded).
has implementation-dependent behavior.
does not scroll. Instead, clear the whole screen and then display the text.
specifies a string that will be searched for before each file is displayed.
starts at line number num.
mount [-hV] mount -a [-fFnrsvw] [-t vfstype] mount [-fnrsvw] [-o options [,...]] device | dir mount [-fnrsvw] [-t vfstype] [-o options] device dir |
All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. mount serves to attach the file system found on some device to the big file tree. Conversely, umount(8) will detach it again.
outputs version.
invokes verbose mode.
mounts all filesystems (of the given types) mentioned in fstab.
combines with -a. to fork off a new incarnation of mount for each device. This will do the mounts on different devices or different NFS servers in parallel.
causes everything to be done except for the actual system call; if it's not obvious, this `fakes' mounting the file system.
mounts without writing in /etc/mtab. This is necessary for example when /etc is on a read-only file system.
tolerates sloppy mount options rather than failing. This will ignore mount options not supported by a filesystem type. Not all filesystems support this option.
mounts the file system read-only. A synonym is -o ro.
mounts the file system read/write. (default) A synonym is -o rw.
mounts the partition that has the specified label.
mounts the partition that has the specified uuid. These two options require the file /proc/partitions to exist.
indicates a file system type of vfstype.
More than one type may be specified in a comma separated list. The list of file system types can be prefixed with no to specify the file system types on which no action should be taken.
options are specified with a -o flag followed by a comma-separated string of options. Some of these options are only useful when they appear in the /etc/fstab file. The following options apply to any file system that is being mounted:
does all I/O to the file system asynchronously.
updates inode access time for each access. (default)
is mountable with -a.
uses default options: rw, suid, dev, exec, auto, nouser, and async.
interprets character or block special devices on the file system.
permits execution of binaries.
does not update inode access times on this file system.
is only explicitly mountable.
does not interpret character or block special devices on the file system.
does not allow execution of any binaries on the mounted file system.
does not allow set-user-identifier or set-group-identifier bits to take effect.
forbids an ordinary (i.e., non-root) user to mount the file system. (default)
attempts to remount an already-mounted file system. This is commonly used to change the mount flags for a file system, especially to make a read-only file system writable.
mounts the file system read-only.
mounts the file system read-write.
allows set-user-identifier or set-group-identifier bits to take effect.
does all I/O to the file system synchronously.
allows an ordinary user to mount the file system. This option implies the options noexec, nosuid, and nodev (unless overridden by subsequent options, as in the option line user,exec,dev,suid).
makes backup before removal.
overrides the usual backup suffix.
removes any trailing slashes from each SOURCE argument.
overrides the usual backup suffix.

passwd changes passwords for user and group accounts. A normal user may only change the password for their own account, the super user may change the password for any account. The administrator of a group may change the password for the group. passwd also changes password expiry dates and intervals.

reads and write all files in binary mode, except for standard output and /dev/tty. This option has no effect on POSIX-compliant systems.
prints the results of applying the patches without actually changing any files.
removes output files that are empty after the patches have been applied. When patch removes a file, it also attempts to remove any empty ancestor directories.
skips patches whose headers do not say which file is to be patched; patches files even though they have the wrong version for the Prereq: line in the patch; assumes that patches are not reversed even if they look like they are.
sets the maximum fuzz factor. This option only applies to diffs that have context, and ignores up to that many lines in looking for places to install a hunk.
controls patch behavior when a file is under RCS or SCCS control and does not exist or is read-only and matches the default version. If num is positive, patch gets (or checks out) the file from the revision control system; if zero, patch ignores RCS and SCCS and does not get the file; and if negative, patch asks the user where to get the file.
works silently, unless an error occurs.
suppresses questions like -f, but makes some different assumptions: skips patches whose headers do not contain file names; skips patches for which the file has the wrong version for the Prereq: line in the patch; and assumes that patches are reversed if they look like they are.
sets the modification and access times of patched files from time stamps given in context diff headers, assuming that the context diff headers use local time.

rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST rsync [OPTION]... [USER@]HOST:SRC DEST rsync [OPTION]... SRC [SRC]... DEST rsync [OPTION]... [USER@]HOST::SRC [DEST] rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST] |
rsync behaves in much the same way that rcp does, but has many more options and uses its remote-update protocol to greatly speedup file transfers when the destination file already exists.
The remote-update protocol allows rsync to transfer just the differences between two sets of files across the network link, using an efficient checksum-search algorithm described in the technical report that accompanies this package.
prints the rsync version number and exits.
increases the amount of information given during the transfer. By default, rsync works silently. A single -v gives information about what files are being transferred and a brief summary at the end. Two -v flags give information on what files are being skipped and slightly more information at the end.
decreases the amount of information given during the transfer, notably suppressing information messages from the remote server. This flag is useful when invoking rsync from cron.
turns off the skipping of files that are already the same length and have the same time-stamp.
forces the sender to checksum all files using a 128-bit MD4 checksum before transfer. The checksum is then explicitly checked on the receiver and any files of the same name which already exist and have the same checksum and size on the receiver are skipped. This option can be quite slow.
is a shortcut for specifying recursion and to preserve all attributes.
copies directories recursively. If not specified, rsync will not copy directories at all.
uses relative paths. This means that the full path names specified on the command line are sent to the server rather than just the last parts of the filenames.
renames preexisting destination files with a ~ extension as each file is transferred. You can control the backup suffix using the --suffix option.
combines with --backup to store all backups in the specified directory. This is very useful for incremental backups.
overrides the default backup suffix used with the -b option. The default is a ~.
skips any files for which the destination file already exists and has a date later than the source file.
recreates symbolic links on the remote system to be the same as the local system. Without this option, all symbolic links are skipped.
transfers the file referenced by a symbolic link, rather than recreating the link.
treats symbolic links that point outside the source tree like ordinary files. Absolute symlinks are also treated like ordinary files, and so are any symlinks in the source path itself when --relative is used.
ignores any symbolic links that point outside the destination tree. All absolute symlinks are also ignored.
recreates hard links on the remote system to be the same as the local system. Without this option hard links are treated like regular files.
does not use the incremental rsync algorithm and sends the whole file as-is instead. This may be useful when using rsync with a local machine.
updates the remote permissions to be the same as the local permissions.
updates the remote owner of the file to be the same as the local owner. This is only available to the super-user. Note that if the source system is a daemon using chroot, --numeric-ids is implied because the source system cannot get access to the usernames.
updates the remote group of the file to be the same as the local group. If the receiving system is not running as the super-user, only groups that the receiver is a member of will be preserved (by group name, not group id number).
transfers character and block device information to the remote system to recreate these devices. This option is only available to the super-user.
transfers modification times along with the files and updates them on the remote system.
does not perform any file transfers, but simply reports the actions it would have taken.
does not cross filesystem boundaries when recursing.
does not create any new files - only updates files that already exist on the destination.
does not delete more than NUM files or directories.
deletes any files on the receiving side that are not on the sending side. Files that are excluded from transfer are excluded from being deleted unless --delete-excluded is specified.
has no effect if directory recursion is not selected.
deletes any files on the receiving side that are excluded, in addition to deleting the files on the receiving side that are not on the sending side. (See --exclude.)
processes file deletions after transferring files, as opposed to the default behavior of deleting before the transfer to ensure that there is sufficient space on the receiving filesystem.
controls the block size used in the rsync algorithm. See the technical report for details.
specifies the remote shell program to use for communication between the local and remote copies of rsync.
You can also choose the remote shell program using the RSYNC_RSH environment variable.
specifies the path to the copy of rsync on the remote machine. Note that this is the full path to the binary, not just the directory that the binary is in.
selectively excludes certain files from the list of files to be transferred.
You may use as many --exclude options on the command line as you like to build up the list of files to exclude.
is like the --exclude option, but instead adds all exclude patterns listed in the file FILE to the exclude list. Blank lines in FILE and lines starting with ´;´ or ´#´ are ignored.
does not exclude the specified pattern of filenames. This is useful as it allows you to build up quite complex exclude/include rules.
specifies a list of include patterns from a file.
instructs rsync to use DIR as a scratch directory when creating temporary copies of the files transferred on the receiving side. The default behavior is to create the temporary files in the receiving directory.
compresses any data from the source file(s) that it sends to the destination machine.
transfers numeric group and user ids rather than using user and group names and mapping them at both ends.
By default rsync will use the user name and group name to determine what ownership to give files. The special uid 0 and the special group 0 are never mapped via user/group names even if --numeric-ids is not specified.
sets a maximum IO timeout in seconds. If no data is transferred for the specified time, rsync will exit. The default is 0, which means no timeout.
specifies an alternate TCP port number to use rather than the default port 873. This only has effect when using rsync to connect to a remote rsync daemon.
specifies whether rsync will use blocking IO when launching a remote shell transport. You may find this is needed for some remote shells that can´t handle the default non-blocking IO.
keeps any partially-transferred file in the event of an incomplete transfer (causing a subsequent transfer of the file remainder to process more rapidly) as opposed to the default behavior of rsync where an incomplete file is deleted.
prints information showing the progress of the transfer.
is equivalent to --partial --progress.
allows you to provide a password in a file for accessing a remote rsync server. Note that this option is only useful when accessing a rsync server using the built in transport, not when using a remote shell as the transport. The file must not be world readable. It should contain just the password as a single line.
specifies a maximum transfer rate in kilobytes per second. A value of zero specifies no limit.
prints out the version of sed that is being run and a copyright notice, then exits.
is equivalent to -n.
is equivalent to -e.
is equivalent to -f.
To deliver electronic mail (email), applications shall support the interface provided by /usr/sbin/sendmail (described here). This interface shall be the default delivery method for applications.
This program sends an email message to one or more recipients, routing the message as necessary. This program is not intended as a user interface routine.
With no flags, sendmail reads its standard input up to an end-of-file or a line consisting only of a single dot and sends a copy of the message found there to all of the addresses listed. It determines the network(s) to use based on the syntax and contents of the addresses.
It is recommended that applications use as few flags as necessary, none if possible.
Some agents allow aliasing on the local system to be prevented by preceding the address with a backslash.
The format of messages must be as defined in RFC 2822.
reads mail from standard input and delivers to the recipient addresses. This is the default mode of operation.
lists information about messages currently in the input mail queue.
uses the SMTP protocol as described in RFC 2821; reads SMTP commands on standard input and writes SMTP responses on standard output.
Note that RFC 2821 specifies \r\n (CR-LF) be used at the end of each line, but Unix pipes almost always use \n (LF) instead. To deal with this, agents will accept both \r\n and \n at the end of each line. When accepting \r\n, the \r before the \n is silently discarded.
explicitly sets the full name of the sender for incoming mail unless the message already contains a From: message header.
If the user running sendmail is not sufficiently trusted, then the actual sender may be indicated in the message, depending on the behavior of the agent.
explicitly sets the envelope sender address for incoming mail. If there is no From: header, the address specified in the From: header will also be set.
If the user running sendmail is not sufficiently trusted, then the actual sender will be indicated in the message.
ignores dots alone on lines by themselves in incoming messages. This option is ignored when -bs is used.
delivers any mail in background, if supported; otherwise ignored.
delivers any mail in foreground, if supported; otherwise ignored.
mails errors back to the sender. (default)
writes errors to the standard error output.
does not send notification of errors to the sender. This only works for mail delivered locally.
writes errors to the sender's terminal using the write(1) command, if he is logged in. Otherwise, mails errors back to the sender. If not supported, reports errors in the same manner as -oem.
is equivalent to -i.
indicates that the sender of a message should receive a copy of the message if the sender appears in an alias expansion. Ignored if aliases are not supported.
reads the message to obtain recipients from the To:, Cc:, and Bcc: headers in the message instead of from the command arguments. If a Bcc: header is present, it is removed from the message unless there is no To: or Cc: header, in which case a Bcc: header with no data is created, in accordance with RFC 2822.
If there are any arguments, they specify addresses to which the message is not to be delivered. That is, the argument addresses are removed from the recipients list obtained from the headers. Note: some agents implement this behavior in reverse, adding addresses instead of removing them. Others may disallow addresses in argument list. Therefore, applications should not put addresses in the argument list if -t is used.
This option is sometimes ignored when not in -bm mode (the default).
is more verbose. Additional -v options may make the software increasingly verbose.
successful completion on all addresses. This does not indicate successful delivery.
there was an error.
This page is believed to reflect functionality provided by smail, exim and other implementations, just not the sendmail implementation.
There has been a suggestion to remove -oew, -ew, -om, -t, and -v. Also to disallow -i when -bs is specified. Most of this strikes me as a good idea, but it might want further discussion. Seems to me that the text "Some agents allow aliasing on the local system to be prevented by preceding the address with a backslash" needs to remain, if the behavior of different implementations really does vary.
shutdown brings the system down in a secure way. All logged-in users are notified that the system is going down, and login(1) is blocked. It is possible to shut the system down immediately or after a specified delay. All processes are first notified that the system is going down by the signal SIGTERM.
uses /etc/shutdown.allow.
tells init(8) to wait sec seconds between sending processes the warning and the kill signal, before changing to another runlevel.
doesn't really shutdown; only sends the warning messages to everybody.
reboots after shutdown.
halts after shutdown.
skips fsck on reboot.
forces fsck on reboot.
cancels an already running shutdown. With this option, it is of course not possible to give the time argument, but you can enter a explanatory message on the command line that will be sent to all users.
specifies when to shut down.
The time argument can have different formats. First, it can be an absolute time in the format hh:mm, in which hh is the hour (1 or 2 digits) and mm is the minute of the hour (in two digits). Second, it can be in the format +m, in which m is the number of minutes to wait. The word now is an alias for +0.
If shutdown is called with a delay, it creates the advisory file /etc/nologin which causes programs such as login(1) to not allow new user logins. shutdown only removes this file if it is stopped before it can signal init (i.e. it is cancelled or something goes wrong). Otherwise it is the responsibility of the system shutdown or startup scripts to remove this file so that users can login.
specifies message to send all users.
Pause for NUMBER seconds. SUFFIX may be s to keep seconds, m for minutes, h for hours or d for days.
compares according to general numerical value, implies -b.

removes debugging symbols only.
strips all symbols that are not needed for relocation processing.
removes symbol symbolname from the source file. This option may be given more than once, and may be combined with other strip options.
puts the stripped output in file, rather than replacing the existing file. When this argument is used, only one objfile argument may be specified.
preserves the access and modification dates of the file.
removes non-global symbols.
removes compiler-generated local symbols. (These usually start with `L' or `.'.)
copies only symbol symbolname from the source file. This option may be given more than once.
does not copy symbol symbolname from the source file. This option may be given more than once, and may be combined with strip options other than -K.
lists all object files modified. In the case of archives, lists all members of the archive.
shows the version number for strip and exits.
su is used to become another user during a login session. Invoked without a username, su defaults to becoming the super user. The optional argument - may be used to provide an environment similar to what the user would expect had the user logged in directly.
The user will be prompted for a password, if appropriate. Invalid passwords will produce an error message. All attempts, both valid and invalid, are logged to detect abuses of the system.
An optional command can be executed. This is done by the shell specified in /etc/passwd for the target user unless the -s or -m options are used. Any arguments supplied after the username will be passed to the invoked shell (shell must support the -c command line option in order for a command to be passed to it).
The current environment is passed to the new shell. The value of $PATH is reset to /bin:/usr/bin for normal users, or /sbin:/bin:/usr/sbin:/usr/bin for the super user. This may be changed with the ENV_PATH and ENV_SUPATH definitions in /etc/login.defs. When using the -m or -p options, the user's environment is not changed.
A subsystem login is indicated by the presense of a "*" as the first character of the login shell. The given home directory will be used as the root of a new filesystem which the user is actually logged into.
makes this a login shell.
passes command to the invoked shell. It is passed directly to the invoked shell (using the shell's -c option), so its syntax is whatever that shell will accept.
does not reset environment variables, and keeps the same shell if it is present in /etc/shells.
uses shell instead of the default in /etc/passwd. The shell specified must be present in /etc/shells.
uses System V sum algorithm, uses 512 bytes blocks.
outputs version information and exits.
tries to open a file even if it is inaccessible when tail starts or if it becomes inaccessible later; useful only with -f.
outputs the last N bytes.
is equivalent to -f.
is equivalent to -n.
performs open/fstat of a file specified by name (if there have been N consecutive iterations for which the size has remained the same) to determine if that file name is still associated with the same device/inode-number pair as before.
if a file has been specified by name, controls how long tail follows the descriptor of a file that continues growing at a rapid pace even after it is deleted or renamed. After detecting N consecutive size changes for a file, open/fstat the file to determine if that file name is still associated with the same device/inode-number pair as before.
terminates after process ID PID dies (only may be specified if -f is).
does not outputs headers giving file names.
sleeps S seconds between iterations (only may be specified if -f is).
outputs headers giving file names.

is equivalent to -p.
displays each available piece of information on the program's resource use on its own line, with an English description of its meaning.
prints the version number of time and exits.
The format string FORMAT controls the contents of the time output. The format string can be set using the -f or --format, -v or --verbose, or -p or --portability options. If they are not given, but the TIME environment variable is set, its value is used as the format string. Otherwise, a built-in default format is used.
The default format is:
%Uuser %Ssystem %Eelapsed %PCPU (%Xtext+%Ddata %Mmax)k
%Iinputs+%Ooutputs (%Fmajor+%Rminor)pagefaults %Wswaps
The format string usually consists of resource specifiers interspersed with plain text. A percent sign (%) in the format string causes the following character to be interpreted as a resource specifier, which is similar to the formatting characters in the printf(3) function.
A backslash (\) introduces a backslash escape, which is translated into a single printing character upon output. \t outputs a tab character, \n outputs a newline, and \\ outputs a backslash. A backslash followed by any other character outputs a question mark (?) followed by a backslash, to indicate that an invalid backslash escape was given.
Other text in the format string is copied verbatim to the output. time always prints a newline after printing the resource use information, so normally format strings do not end with a newline character (or 0).
There are many resource specifications. Not all resources are measured by all versions of Unix, so some of the values might be reported as zero. Any character following a percent sign that is not listed in the table below causes a question mark (`?') to be output, followed by that character, to indicate that an invalid resource listed in the table below causes a question mark (`?') to be output, followed by that character, to indicate that an invalid resource specifier was given.
The resource specifiers, which are a superset of those recognized by the tcsh(1) builtin `time' command, are:
literal `%'.

When invoked without the -D option, useradd creates a new user account using the values specified on the command line and the default values from the system. The new user account will be entered into the system files as needed, the home directory will be created, and initial files copied, depending on the command line options.
When invoked with the -D option, useradd will either display the current default values, or update the default values from the command line. If no options are specified, useradd displays the current default values.

specifies the number of days after a password expires until the account is permanently disabled. A value of 0 disables the account as soon as the password has expired, and a value of -1 disables the feature. The default value is -1.
specifies the group name or number of the user's initial login group. The group name must exist. A group number must refer to an already existing group. If -g is not specified, the implementation will follow the normal user default for that system. This may create a new group or choose a default group that normal users are placed in. Applications which require control of the groups into which a user is placed should specify -g.
specifies a list of supplementary groups which the user is also a member of. Each group is separated from the next by a comma, with no intervening whitespace. The groups are subject to the same restrictions as the group given with the -g option. The default is for the user to belong only to the initial group.
specifies the user's home directory will be created if it does not exist. The files contained in skeleton_dir will be copied to the home directory if the -k option is used, otherwise the files contained in /etc/skel will be used instead. Any directories contained in skeleton_dir or /etc/skel will be created in the user's home directory as well. The -k option is only valid in conjunction with the -m option. The default is to not create the directory and to not copy any files.
is the encrypted password, as returned by crypt(3). The default is to disable the account.
creates a system account, that is, a user with a UID in the range reserved for system account users. If there is not a UID free in the reserved range the command will fail.
specifies the name of the user's login shell. The default is to leave this field blank, which causes the system to select the default login shell.
specifies the numerical value of the user's ID. This value must be unique, unless the -o option is used. The value must be non-negative. The default is the smallest ID value greater than 499 which is not yet used.
specifies the initial path prefix for a new user's home directory. The user's name will be affixed to the end of default_home to create the new directory name if the -d option is not used when creating a new account.
specifies the date on which the user account is disabled.
specifies the number of days after a password has expired before the account will be disabled.
specifies the group name or ID for a new user's initial group. The named group must exist, and a numerical group ID must have an existing entry.
specifies the name of the new user's login shell. The named program will be used for all future new user accounts.
specifies the new user's password file comment field value.
Delete the user account named login. If there is also a group named login, this command may delete the group as well, or may leave it alone.
removes files in the user's home directory along with the home directory itself. Files located in other file system will have to be searched for and deleted manually.
usermod [-c comment] [-d home_dir [ -m]]
[-e expire_date] [-f inactive_time]
[-g initial_group] [-G group[,...]]
[-l login_name] [-p passwd]
[-s shell] [-u uid [ -o]] login |
specifies the new value of the user's password file comment field.
specifies the user's new login directory. If the -m option is given the contents of the current home directory will be moved to the new home directory, which is created if it does not already exist.
specifies the date on which the user account will be disabled. The date is specified in the format YYYY-MM-DD.
specifieshe number of days after a password expires until the account is permanently disabled. A value of 0 disables the account as soon as the password has expired, and a value of -1 disables the feature. The default value is -1.
specifies the group name or number of the user's new initial login group. The group name must exist. A group number must refer to an already existing group.
specifies a list of supplementary groups which the user is also a member of. Each group is separated from the next by a comma, with no intervening whitespace. The groups are subject to the same restrictions as the group given with the -g option. If the user is currently a member of a group which is not listed, the user will be removed from the group.
changes the name of the user from login to login_name. Nothing else is changed. In particular, the user's home directory name should probably be changed to reflect the new login name.
is the encrypted password, as returned by crypt(3).
specifies the name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.
specifies the numerical value of the user's ID. This value must be unique, unless the -o option is used. The value must be non-negative. Any files which the user owns and which are located in the directory tree rooted at the user's home directory will have the file user ID changed automatically. Files outside of the user's home directory must be altered manually.

outputs version information and exits.
terminates input filenames by a null character instead of by whitespace, and the quotes and backslash are not special (every character is taken literally). Disables the end of file string, which is treated like any other argument. Useful when arguments might contain white space, quote marks, or backslashes. The GNU find -print0 option produces input suitable for this mode.

runs up to max-procs processes at a time; the default is 1. If max-procs is 0, xargs will run as many processes as possible at a time. Use the -n option with -P; otherwise chances are that only one exec will be done.
The shell is POSIX-1003.2 with the following exceptions.
POSIX Standard, section 3.9.1.1, line 779-784.
When the search for command name using the PATH environment variable succeeds, the command is executed with actions equivalent to calling 'execve()' with the path argument set to the pathname resulting from the search, 'argv[0]' set to the command name and the remaining arguments set to the operands.
if [ $0 = (basename $0) ]; then echo "command name: " $0 fi |
GNU Exception:
When the search for command name using the PATH environment variable succeeds, the command is executed with actions equivalent to calling 'execve()' with the path argument set to the pathname resulting from the search, 'argv[0]' set to the full-path command name and the remaining arguments set to the operands.
if [ $0 = (realpath $0) ]; then echo "full pathname: " $0 fi |
When PATH is used to locate a file for the dot utility, and a matching file is on the PATH but is not readable, the behavior is undefined (unlike POSIX which apparently requires the shell to continue searching through the rest of the PATH, POSIX Standard, section 3.14.4, line 1493-1498).
Among the many shells existing at the time of evaluation, the two most compliant were Bash and Pdksh.
At the time of evaluation, Bash was found mostly compliant with the POSIX-1003.2 standard, and its maintainer demonstrated interest in bringing the shell to full compliance. Bash already enjoys wide use among shell users, and is even included in many distributions as the default shell. Further, the abundance of documentation found both on the Internet and in the bookstore makes Bash an easy shell to use.
Of course, shell scripts must avoid using bash extensions if they want to run on any LSB system.
The two exceptions to POSIX (concerning . and non-readable files, and argv[0]) in this section are to accommodate bash. The need for exceptions should be reviewed if bash changes or POSIX changes to remove the conflict. Future versions of this standard may also consider exceptions for pdksh or other almost-compliant shells, if they seem to be warranted.
A "user name" is a string that is used to identify a user. A "login name" is a user name that is associated with a system login. A "user id" is a non negative integer, which can be contained in an object of type uid_t, that is used to identify a system user.
When the identity of a user is associated with a process, a user ID value is referred to as a real user ID, or an effective user ID. [POSIX 1003.1-1996]
A "group name" is a string that is used to identify a set of users. A "group id" is a non negative integer, which can be contained in a object of type gid_t, that is used to identify a group of system users. Each system user is a member of at least one group. When the identity of a group is associated with a process, a group ID value is referred to as a real group ID, or an effective group ID. [POSIX 1003.1-1996]
The format of the User and Group databases is not specified. Programs may only read these databases using the provided API. Changes to these databases should be made using the provided commands.
Below is a table of required mnemonic user and group names. This specification makes no attempt to numerically assign uid or gid numbers. The exceptions are the uid and gid for "root" which is equal to 0, and the uid and gid for "bin" which is equal to 1.
Table 16-1. Required User & Group Names
| User | Group | Comments |
| root | root | Administrative user with no restrictions |
| bin | bin | Administrative user with some restrictions |
| daemon | daemon | Subprocess special privileges |
Below is a table of optional mnemonic user and group names. This specification makes no attempt to numerically assign uid or gid numbers. If the username exists on a system, then they should be in the suggested corresponding group.
Table 16-2. Optional User & Group Names
| User | Group | Comments |
| adm | adm | Administrative special privileges |
| lp | lp | Printer special privileges |
| sync | sync | Login to sync the system |
| shutdown | shutdown | Login to shutdown the system |
| halt | halt | Login to halt the system |
| Mail special privileges | ||
| news | news | News special privileges |
| uucp | uucp | UUCP special privileges |
| operator | root | Operator special privileges |
| man | man | Man special privileges |
| nobody | nobody | Used by NFS |
The differences in numeric values of the uids and gids between systems on a network can be reconciled via NIS, rdist(1), rsync(1), or ugidd(8). Only a minimum working set of "user names" and their corresponding "user groups" are required. Applications cannot assume non system user or group names will be defined.
Applications cannot assume any policy for the default umask or the default directory permissions a user may have. Applications should enforce user only file permissions on private files such as mailboxes. The location of the users home directory is also not defined by policy other than the recommendations of the FHS and must be obtained by the *pwnam(3) calls.
The system UIDs from 0 to 99 should be statically allocated by the system. These static assignments should be defined by a common registry.
The system UIDs from 100 to 499 should be reserved for dynamically allocation by system administrators and post install scripts using useradd(1).
An LSB conforming system must adhere to the FHS 2.2.
The FHS allows many components or subsystems to be optional. An application must check for the existence of an optional component before using it, and should behave in a reasonable manner if the optional component is not present.
The following device nodes must exist under /dev. Other devices may also exist in /dev.
All data written to this device is discarded. A read from this device will return an EOF condition.
This device is a source of zeroed out data. All data written to this device is discarded. A read from this device will return as many bytes containing the value zero as was requested.
This device is a synonym for the controlling terminal of a process. Once this device is opened, all reads and writes will behave as if the actual controlling terminal device had been opened.
In this Chapter "System" means an "LSB-compliant system" and "application" means an "LSB-compliant (third party vendor) application".
The system must grant to the application read and execute permissions needed to use all system interfaces (ABIs) mentioned in the LSB document and included standards.
The application should not depend on having directory write permission outside /tmp, /var/tmp, its home directory and /var/opt/package, (where package is the name of the application package).
The application should not depend on owning these directories.
For these directories the application should be able to work with directory write permissions restricted by the "sticky bit". (Which prevents the application from removing files owned by another user. This is classically done with /tmp, to prevent accidental deletion of "foreign" files.)
The application should not depend on file write permission on files not owned by the user it runs under with the exception of its personal inbox /var/mail/username
The application should not depend on having read permission to every file and directory.
The application should not depend on the suid/sgid permissions of a file not packaged with the application. Instead, the distribution is responsible for assuming that all system commands have the required permissions and work correctly.
Rationale: Let us make security officers happy. Let's give them the freedom to take sgid/suid perms away, as long as they do not break the system's functionality.
"Normal" applications should not depend on running as a privileged user.
Special applications that have a reason to run under a privileged user, should outline these reasons clearly in their documentation, if they are not obvious as in the case of a backup/restore program. Users of the application should be informed, that "this application demands security privileges, which could interfere with system security".
The application should not contain binary-only software that requires being run as root, as this makes security auditing harder or even impossible.
The application should not change permissions of files and directories that do not belong to its own package. To do so without a warning notice in the documentation is regarded as unfriendly act.
The application should be prepared to address removable media being mounted with options such as "noauto", "nouser", "nosuid" or "nodev". Also, the mount options "uid=X", "gid=X" should be awaited with a non-zero uid/gid value X.
Rationale: System vendors and local system administrators want to run applications from removable media, but want the possibility to control what the application can do.
Run-from-removable media applications should not depend on logging in as a privileged user.
If the installation of an application requires the execution of programs with superuser privileges, such programs should also be supplied in a human-readable form.
Without this, the local system administrator would have to blindly trust a piece of software, particularly its security.
Packages may not touch the configuration file /etc/crontab, nor may they modify the files in /var/spool/cron/crontabs.
If a package wants to install a job that has to be executed via cron, it shall place a file with the name of the package in one of the following directories:
/etc/cron.daily /etc/cron.weekly /etc/cron.monthly |
As these directory names say, the files within them are executed on a daily, weekly, or monthly basis, respectively.
If a certain job has to be executed more frequently than daily, the package shall install a file /etc/cron.d/<package-name> tagged as configuration file. This file uses the same syntax as /etc/crontab and is processed by cron automatically.
It is recommended that files installed in any of these directories be scripts (shell scripts, Perl scripts, etc.) so that they may be modified by the local system administrator. In addition, they must be registered as configuration file.
The scripts in these directories have to check, if all necessary programs are installed before they try to execute them. Otherwise, problems will arise when a package was removed (but not purged), since the configuration files are kept on the system in this situation.
To avoid namespace conflicts in the /etc/cron.* directories, the filenames used by LSB-compliant packages in /etc/cron.daily, /etc/cron.weekly, /etc/cron.monthly, or /etc/cron.d must come from a managed namespace. These filenames may be assigned using one of the following methods:
Assigned namespace. This namespace consists of names which only use the character set [a-z0-9]. In order to avoid conflicts these cron script names must be reserved through the Linux Assigned Names and Numbers Authority (LANANA). Information about the LANANA may be found at www.lanana.org.
Commonly used names shall be reserved in advance; developers for projects should be encouraged reserve names from LANA, so that each distribution can use the same name, and to avoid conflicts with other projects.
Hierarchical namespace. This namespace consists of scripts names which look like this: [hier1]-[hier2]-...-[name], where name is again taken the character set [a-z0-9], and where there may be one or more [hier-n] components. [hier1] may either be an LSB provider name assigned by the LANANA, or it may be owners' DNS name in lower case, with at least one '.'. I.e., "debian.org", "staroffice.sun.com", etc. The LSB provider name assigned by LANANA must only consist of the ASCII characters [a-z0-9].
Reserved namespace. This namespace consists of script names which begin with the character '_', and is reserved for distribution use only. This namespace should be used for core packages only, and in general use of this namespace is highly discouraged.
| 0 | halt |
| 1 | single user mode |
| 2 | multiuser with no network services exported |
| 3 | normal/full multiuser |
| 4 | reserved for local use, default is normal/full multiuser |
| 5 | multiuser with xdm or equivalent |
| 6 | reboot |
Init files shall accept one argument, saying what to do:
| start | start the service |
| stop | stop the service |
| restart | stop and restart the service if the service is already running, otherwise start the service |
| reload | cause the configuration of the service to be reloaded without actually stopping and restarting the service |
| force-reload | cause the configuration to be reloaded if the service supports this, otherwise restart the service |
| status | print the current status of the service |
The start, stop, restart, force-reload, and status commands must be supported by all init files; the reload option is optional. Other init script actions may be defined by the init script.
Init files must ensure that they will behave sensibly if invoked with start when the service is already running, or with stop when it isn't, and that they don't kill unfortunately-named user processes. The best way to achieve this is to use the init-script functions provided by /lib/lsb/init-functions.
If a service reloads its configuration automatically (as in the case of cron, for example), the reload option of the init file must behave as if the configuration has been reloaded successfully.
These executable files must not fail obscurely when the configuration files remain but the package has been removed, as the default in [the packaging system] is to leave configuration files on the system after the package has been removed. Only when it is executed with the [purge] option will [the packaging system] remove configuration files. Therefore, you should include a test statement at the top of the file, like this:
test -f program-executed-later-in-file || exit 5 |
If the status command is given, the init script will return the following exit status codes.
| 0 | program is running or service is OK |
| 1 | program is dead and /var/run pid file exists |
| 2 | program is dead and /var/lock lock file exists |
| 3 | program is stopped |
| 4 | program or service status is unknown |
| 5-99 | reserved for future LSB use |
| 100-149 | reserved for distribution use |
| 150-199 | reserved for application use |
| 200-254 | reserved |
In the case of init script commands other than "status" (i.e., "start", "stop", "restart", "reload", and "force-reload"), the init script must return an exit status of zero if the action described by the argument has been successful. Otherwise, the exit status shall be non-zero, as defined below. In addition to straightforward success, the following situations are also to be considered successful:
restarting a service (instead of reloading it) with the "force-reload" argument
running "start" on a service already running
running "stop" on a service already stopped or not running
running "restart" on a service already stopped or not running
In case of an error, while processing any init script action except for "status", the init script must print an error message and return one of the following non-zero exit status codes.
| 1 | generic or unspecified error (current practice) |
| 2 | invalid or excess argument(s) |
| 3 | unimplemented feature (for example, "reload") |
| 4 | user had insufficient privilege |
| 5 | program is not installed |
| 6 | program is not configured |
| 7 | program is not running |
| 8-99 | reserved for future LSB use |
| 100-149 | reserved for distribution use |
| 150-199 | reserved for application use |
| 200-254 | reserved |
All error messages must be printed on standard error. All status messages must be printed on standard output.
Since init files may be run manually by a system administrator with non-standard environment variable values for PATH, USER, LOGNAME, etc. init files must not depend on the values of these environment variables. They should set them to some known/default values if they are needed.
LSB applications which need to execute script(s) at bootup and/or shutdown may provide one or more init.d files. These files are installed by the install_initd program described below, which copies it into a standard directory and makes whatever other adjustments (creation of symlinks, creation of entries in a database, etc.) are necessary so that the script can be run at boot-time. [39]
In the init.d file, information about the shell script shall be delimited by the lines "### BEGIN INIT INFO" and "### END INIT INFO". These delimiter lines may containg trailing whitespace, which shall be ignored. Inside this block there shall be lines of the form "# {keyword}: [arg1] [arg2] ...". (All lines inside this block start with a hash ('#') character in the first column, so that shell treats them as comments.) The following keywords, with their arguments are defined in this specification:
# Provides: boot_facility_1 [ boot_facility_2 ...] # Required-Start: boot_facility_1 [ boot_facility_2 ...] # Required-Stop: boot_facility_1 [ boot_facility_2 ...] # Default-Start: run_level_1 [ run_level_2 ...] # Default-Stop: run_level_1 [ run_level_2 ...] # Short-Description: short_description # Description: multiline_description |
Additional keywords may be defined in future LSB specifications. Distributions may define local extensions by using the prefix "X-[distribution name]" --- for example, "X-RedHat-foobardecl", or "X-Debian-xyzzydecl".
An init.d shell script may declare using the "Required-Start: " header that it must not be run until certain boot facilities are provided. This information is used by the installation tool or the boot-time boot-script execution facility to assure that init scripts are run in the correct order. When an init script is run with a "start" argument, the boot facility or facilities specified in the "Provides" header shall be considered present, and hence init scripts which require those boot facilities would then be eligble to be run. When an init script is run with a "stop" argument, the boot facilities specified in the "Provides" header are considered no longer present. Details about how the naming conventions used by boot facilities, and system facilties defined by this specification can be found in a following section.
Similarly, the "Required-Stop:" header defines which facilities must still be available during the shutdown of that service. Hence, the init script system should avoid stopping shell scripts which provide those facilities until this shell script is stopped.
The "Default-Start" and "Default-Stop" headers define which run levels should by default run the script with a start or stop argument, respectively, to start or stop the services controlled by the init script.
The "Short-Description" and "Description" header fields are used to provide text which describes the actions of the init script. The "short_description" shall be a relatively short, pithy description of the init script, where as the "multiline_description" can be a much longer piece of text that may span mulitple lines. In a multiline description, each continuation line must begin with a '#' followed by tab character or a '#' followed by at least two space characters. The multiline description is terminated by the first line that does not match this criteria.
An init.d file is installed by copying it into /etc/init.d (which may be a symlink to another location). This can be done by the package installer. During the package's postinstall script, the program "/usr/lib/lsb/install_initd" configures the distribution's boot script system to call the package's init.d file at the appropriate time.
The install_initd program takes a single argument, the pathanme to the /etc/init.d file. For example:
/usr/lib/lsb/install_initd /etc/init.d/inet |
When a software package is removed, the package's preuninstall script shall call /usr/lib/lsb/remove_initd and pass the pathname to the /etc/init.d file. The package manager is still responsible for removing the /etc/init.d file; the remove_initd program is provided in case the distribution needs to clean up any other modifications in the distribution's boot script system that might have been made by the install_initd program. For example:
/usr/lib/lsb/remove_initd /etc/init.d/inet |
There should be a tool available to the user (e.g., RedHat's chkconfig) which can be used by the system administrator to easily manipulate at which init levels a particular init.d script is started or stopped. This specification currently does not specify such an interface, however.
Boot facilities are used to indicate dependencies in init scripts, as defined in a previous section. Facility names that begin with a dollar sign ('$') are system facility names, defined by the LSB, and MUST be provided by distributions. LSB applications must not provide system facilities. This document defines the following system facility names:
| $local_fs | all local filesystems are mounted |
| $network | low level networking (ethernet card; may imply PCMCIA running) |
| $named | named is operational |
| $remote_fs | all remote filesystems are mounted (note in some cases /usr may be remote. Most applications that care will probably require both $local_fs and $remote_fs) |
| $syslog | system logger is operational |
| $netdaemons | all network daemons are running |
Other (non-system) facilities may be defined by other LSB applications. These facilities shall be named using the same conventions defined for naming init.d script names. Commonly, the facility provided by an LSB application init.d script will have the same name as the name assigned to the init.d script.
Since the init.d scripts must live in a single directory, they must come from a single namespace. Three means of assigning names from this namespace are available:
Assigned namespace. This namespace consists of names which only use the character set [a-z0-9]. This space is desirable for scripts which system administrators may often wish to run manually: e.g., "/etc/init.d/named restart" In order to avoid conflicts these init.d names must be reserved through the Linux Assigned Names and Numbers Authority (LANANA). Information about the LANANA may be found at www.lanana.org.
Commonly used names shall be reserved in advance; developers for projects should be encouraged to reserve names from LANANA, so that each distribution can use the same name, and to avoid conflicts with other projects.
Hierarchical namespace. This namespace consists of scripts names which look like this: [hier1]-[hier2]-...-[name], where name is again taken the character set [a-z0-9], and where there may be one or more [hier-n] components. [hier1] may either be an LSB provider name assigned by the LANANA, or it may be owners' DNS name in lower case, with at least one '.' (e.g., "debian.org", "staroffice.sun.com"). The LSB provider name assigned by LANANA must only consist of the ASCII characters [a-z0-9].
Reserved namespace. This namespace consists of script names which begin with the character '_', and is reserved for distribution use only. This namespace should be used for core packages only, and in general use of this namespace is highly discouraged.
In general, if a package or some system function is likely to be used on multiple systems, the package developers or the distribution SHOULD get a registered name through LANANA, and distributions should strive to use the same name whenever possible. For applications which may not be "core" or may not be commonly installed, the hierarchical namespace may be more appropriate. An advantage to the hierarchical namespace is that there is no need to consult with the LANANA before obtaining an assigned name.
Short names are highly desirable, since many system administrators like to use them to manually start and stop services. Given this, they should be standardized on a per-package basis. This is the rationale behind having a LANANA organization to assign these names. The LANANA may be called upon to handle other namespace issues, such as package/prerequisites naming (which is essential to making prerequisites to work correctly).
This specification shall pre-define the following script names as being reserved to the LANA. They reflect names which are commonly in use today by distributions to start up various system programs/daemons. The behavior of these scripts are not specified here, and not all distributions may use all of these script names.

Each LSB-compliant init.d script must source the file /lib/lsb/init-functions. This file must cause the following shell script commands to be defined. This can be done either by adding a directory to the PATH variable which defines these commands, or by defining sh aliases. While the distribution-provided aliases may choose to use bash extensions (at the distribution's option), the LSB init.d files themselves should only depend in /bin/sh features as defined by POSIX.2.
| start_daemon [-f] [-n nicelevel] pathname [args] | This runs the specified program as a daemon. start_daemon will check to see if there is a program named "daemon" already running. If so, it will not start another copy of the daemon unless the -f option is given. The -n option specifies a nice level. See nice(1). |
| killproc basename [signal] | This stops the specified program. The program is found using the algorithm given by pidofproc. If a signal is specified, the program is sent that signal. Otherwise, a SIGTERM followed by a SIGKILL after some number of seconds is sent. |
| pidofproc basename | This function returns one or more pid(s) for a particular daemon. If an entry is found in /var/run/basename.pid, then that value is returned. Compliant implementations of the LSB may attempt other mechanisms for determining the pid(s), although this is not required (and not recommended, since a user can trick startup scripts by creating processes that appear to be system programs in the process list thus creating a potential security exposure). Hence, LSB-complaint applications who wish to use the pidofproc function in their init scripts must store the pid in /var/run/basename.pid. |
| log_success_msg "message" | This requests the distribution to print a success message. The message should be relatively short; no More than 60 characters is highly desirable. |
| log_failure_msg "message" | This requests the distribution to print a failure message. The message should be relatively short; no more than 60 characters is highly desirable. |
| log_warning_msg "message" | This requests the distribution to print a warning message. The message should be relatively short; no more than 60 characters is highly desirable. |

| [35] | Some versions of RPM may produce packages which contain extensions or modifications to the RPM package format beyond what has been documented in the appendix of the Maximum RPM book. An LSB-conformant package must not contain any of these extensions, in order to assure interoperability with the largest number of versions of RPM and packaging systems which understand how to import RPM format packages. |
| [36] | The distribution itself may use a different packaging format for its own packages, and of course it may use any available mechanism for installing the LSB-conformant packages. |
