Positions new files in archive after the file named by the posname operand.

Positions new files in archive before the file named by the posname operand.

Suppresses the diagnostic message that is written to standard error by default when archive is created.

Prevents extracted files from replacing like-named files in the file system. This option is useful when -T is also used to prevent truncated file names from replacing files with the same prefix.

Deletes one or more files from archive.

Positions new files in archive before the file named by the posname operand. This option is equivalent to -b.

Moves files. If -a, -b, or -i with the posname operand are specified, the -m option moves files to the new position. Otherwise, -m moves files to the end of archive.

Prints the contents of files in archive to standard output. If no files are specified, the contents of all files in archive are written in the order of the archive.

Quickly appends files to the end of archive. Positioning options -a, -b, and -i are invalid. The command does not check whether the added files are already in archive. This option is useful to avoid quadratic behavior when creating a large archive piece-by-piece.

Replaces or adds files in archive. If archive does not exist, a new archive file is created and a diagnostic message is written to standard error, unless the -c option is specified. If no files are specified and the archive exists, the results are undefined. Files that replace existing files do not change the order of the archive. If the -u option is used with the -r option, only those files with dates of modification later than the archive files are replaced. If the -a, -b, or -i option is used, the posname argument must be present and specifies that new files are to be placed after (-a) or before (-b or -i) posname. Otherwise, the new files are placed at the end.

Forces the regeneration of the archive symbol table even if ar is not invoked with an option that will modify the archive contents. This command is useful to restore the archive symbol table after the strip(1) command has been used on the archive.

Prints a table of contents of archive. The files specified by the file operands are included in the written list. If no file operands are specified, all files in archive are included in the order of the archive.

Allows file name truncation of extracted files whose archive names are longer than the file system can support. By default, extracting a file with a name that is too long is an error. In that case, a diagnostic message is written and the file is not extracted.

Updates older files. When used with the -r option, files within archive are replaced only if the corresponding file has a modification time that is at least as new as the modification time of the file within archive.

Gives verbose output. When used with options -d, -r, or -x, the -v option writes a detailed file-by-file description of the archive creation and the constituent files, and maintenance activity. When used with -p, -v writes the name of the file to the standard output before writing the file itself to the standard output. When used with -t, -v includes a long listing of information about the files within the archive. When used with -x, -v prints the filename preceding each extraction. When writing to an archive, -v writes a message to the standard error.

Prints its version number on standard error.

Same as the /usr/bin/ar version, except when writing to an archive, no message is written to the standard error.

Extracts the files named by the file operands from archive. The contents of archive are not changed. If no file operands are given, all files in archive are extracted. If the file name of a file extracted from archive is longer than that supported in the directory to which it is being extracted, the results are undefined. The modification time of each file extracted is set to the time file is extracted from archive.

A path name of the archive file.

A path name. Only the last component is used when comparing against the names of files in the archive. If two or more file operands have the same last path name component (see basename(1)), the results are unspecified. The implementation's archive format will not truncate valid file names of files added to or replaced in the archive.

The name of a file in the archive file, used for relative positioning. See options -m and -r.

Determine the pathname that overrides the default directory for temporary files, if any.

Determine the timezone used to calculate date and time strings written by ar -tv. If TZ is unset or null, an unspecified default timezone is used.

Successful completion.
