DESCRIPTION
The ar utility maintains groups of files combined into a single archive
file. Its main use is to create and update library files. However, it
can be used for any similar purpose. The magic string and the file
headers used by ar consist of printable ASCII characters. If an archive
is composed of printable files, the entire archive is printable.
When ar creates an archive, it creates headers in a format that is por‐
table across all machines. The portable archive format and structure
are described in detail in ar.h(3HEAD). The archive symbol table
described there is used by the link editor ld(1) to effect multiple
passes over libraries of object files in an efficient manner. An ar‐
chive symbol table is only created and maintained by ar when there is
at least one object file in the archive. The archive symbol table is in
a specially named file that is always the first file in the archive.
This file is never mentioned or accessible to the user. Whenever the ar
command is used to create or update the contents of such an archive,
the symbol table is rebuilt. The -s option described below forces the
symbol table to be rebuilt.
OPTIONS
The following options are supported:
-a posname
Positions new files in archive after the file named by posname.
-b posname
Positions new files in archive before the file named by posname.
-c
Suppresses the diagnostic message that is written to standard error
by default when archive is created.
-C
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.
-d
Deletes one or more files from archive.
-i posname
Positions new files in archive before the file named by posname.
This option is equivalent to -b.
-m
Moves files. If -a, -b, or -i are specified, the -m option moves
files to the new position. Otherwise, -m moves files to the end of
archive.
-p
Prints the contents of files in archive to standard output. If no
files are specified, the contents of all files in archive are writ‐
ten in the order of the archive.
-q
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.
-r
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. 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.
The -a, -b, or -i options can be used to specify the position at
which the new files are to be placed. Otherwise, the new files are
placed at the end.
-s
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.
-S
When building the archive symbol table, force the use of the 64-bit
capable symbol table format. By default, the 32-bit format is used
for all archives smaller than 4GB, and the larger format is used
for larger archives that exceed the 32-bit limit.
-t
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.
-T
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.
-u
Updates older files. When used with the -r option, files within ar‐
chive are replaced only if the corresponding file has a modifica‐
tion time that is at least as new as the modification time of the
file within archive.
-v
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 pre‐
ceding each extraction. When writing to an archive, -v writes a
message to the standard error.
-V
--version
Print version information.
-x
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 direc‐
tory 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.
-?
--help
Print usage message and immediately exit.
/usr/xpg4/bin/ar
The following options are supported for /usr/xpg4/bin/ar:
-v Same as the /usr/bin/ar version, except when writing to an ar‐
chive, no message is written to the standard error.
OPERANDS
The following operands are supported:
archive A path name of the archive file.
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 implementa‐
tion's archive format will not truncate valid file names of
files added to or replaced in the archive.
ENVIRONMENT VARIABLES
See environ(7) for descriptions of the following environment variables
that affect the execution of ar: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES,
LC_TIME, and NLSPATH.
TMPDIR Determine the pathname that overrides the default directory
for temporary files, if any.
TZ Determine the time zone used to calculate date and time
strings written by ar -tv. If TZ is unset or null, an
unspecified default time zone is used.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.

NOTES
If the same file is mentioned twice in an argument list, it may be put
in the archive twice.
By convention, archives are suffixed with ".a".
To support historical convention, the '-' for the first command line
option can be omitted.
When inserting ELF objects into an archive file, ar might add \n char‐
acters to pad these objects to an 8-byte boundary. Such padding
improves the efficiency with which ld(1) can access the archive. Only
ELF object files are padded in this way. Other archive members are not
altered. When an object with such padding is extracted from an archive,
the padding is not included in the resulting output.
It is faster to create a new archive from scratch than to insert indi‐
vidual files into an existing archive via separate calls to ar. When
possible, the recommended strategy is to remove the existing archive,
and re-create it with a single ar invocation.
The overall size of an archive is allowed to exceed 4GB. However, the
size of any individual file within an archive is limited to 4GB by the
archive file format. See ar.h(3HEAD).
The maximum user ID and group ID for an individual file within an ar‐
chive are limited to 6 decimal digits by the archive file format. Any
file with a user or group ID greater than 999999 is quietly set to user
ID "nobody" (60001) or group ID "nobody" (6001). See ar.h(3HEAD).
