- The _a_r utility creates and maintains groups of files com-
- bined into an archive. Once an archive has been created,
- new files can be added and existing files can be
- extracted, deleted, or replaced.
-
- Files are named in the archive by a single component,
- i.e., if a file referenced by a path containing a slash
- (``/'') is archived it will be named by the last component
- of that path. When matching paths listed on the command
- line against file names stored in the archive, only the
- last component of the path will be compared.
-
- All informational and error messages use the path listed
- on the command line, if any was specified, otherwise the
- name in the archive is used. If multiple files in the
- archive have the same name, and paths are listed on the
- command line to ``select'' archive files for an operation,
- only the ffiirrsstt file with a matching name will be selected.
-
- The normal use of _a_r is for the creation and maintenance
- of libraries suitable for use with the loader (see _l_d(1))
- although it is not restricted to this purpose. The
- options are as follows:
-
- -a A positioning modifier used with the options -r and
- -m. The files are entered or moved aafftteerr the
- archive member _p_o_s_i_t_i_o_n, which must be specified.
-
- -b A positioning modifier used with the options -r and
- -m. The files are entered or moved bbeeffoorree the
- archive member _p_o_s_i_t_i_o_n, which must be specified.
-
- -c Whenever an archive is created, an informational
- message to that effect is written to standard
- error. If the -c option is specified, _a_r creates
- the archive silently.
-
- -d Delete the specified archive files.

-
- -i Identical to the -b option.
-
- -m Move the specified archive files within the
- archive. If one of the options -a, -b or -i are
- specified, the files are moved before or after the
- _p_o_s_i_t_i_o_n file in the archive. If none of those
- options are specified, the files are moved to the
- end of the archive.
-
- -o Set the access and modification times of extracted
- files to the modification time of the file when it
- was entered into the archive. This will fail if
- the user is not the owner of the extracted file or
- the super-user.
-
- -p Write the contents of the specified archive files
- to the standard output. If no files are specified,
- the contents of all the files in the archive are
- written in the order they appear in the archive.
-
- -q (Quickly) append the specified files to the
- archive. If the archive does not exist a new
- archive file is created. Much faster than the -r
- option, when creating a large archive piece-by-
- piece, as no checking is done to see if the files
- already exist in the archive.
-
- -r Replace or add the specified files to the archive.
- If the archive does not exist a new archive file is
- created. Files that replace existing files do not
- change the order of the files within the archive.
- New files are appended to the archive unless one of
- the options -a, -b or -i is specified.
-
- -T Select and/or name archive members using only the
- first fifteen characters of the archive member or
- command line file name. The historic archive for-
- mat had sixteen bytes for the name, but some his-
- toric archiver and loader implementations were
- unable to handle names that used the entire space.
- This means that file names that are not unique in
- their first fifteen characters can subsequently be
- confused. A warning message is printed to the
- standard error output if any file names are trun-
- cated. (See _a_r(5) for more information.)
-
- -t List the specified files in the order in which they
- appear in the archive, each on a separate line. If
- no files are specified, all files in the archive
- are listed.
-
- -u Update files. When used with the -r option, files
- in the archive will be replaced only if the disk
- file has a newer modification time than the file in

-
- the archive. When used with the -x option, files
- in the archive will be extracted only if the
- archive file has a newer modification time than the
- file on disk.
-
- -v Provide verbose output. When used with the -d, -m,
- -q or -x options, _a_r gives a file-by-file descrip-
- tion of the archive modification. This description
- consists of three, white-space separated fields:
- the option letter, a dash (``-'') and the file
- name. When used with the -r option, _a_r displays
- the description as above, but the initial letter is
- an ``a'' if the file is added to the archive and an
- ``r'' if the file replaces a file already in the
- archive.
-
- When used with the -p option, the name of each
- printed file is written to the standard output
- before the contents of the file, preceded by a sin-
- gle newline character, and followed by two newline
- characters, enclosed in less-than (``<'') and
- greater-than (``>'') characters.
-
- When used with the -t option, _a_r displays an ``ls
- -l'' style listing of information about the members
- of the archive. This listing consists of eight,
- white-space separated fields: the file permissions
- (see _s_t_r_m_o_d_e(3)), the decimal user and group ID's,
- separated by a single slash (``/''), the file size
- (in bytes), the file modification time (in the
- _d_a_t_e(1) format ``%b %e %H:%M %Y''), and the name of
- the file.
-
- -x Extract the specified archive members into the
- files named by the command line arguments. If no
- members are specified, all the members of the
- archive are extracted into the current directory.
-
- If the file does not exist, it is created; if it
- does exist, the owner and group will be unchanged.
- The file access and modification times are the time
- of the extraction (but see the -o option). The
- file permissions will be set to those of the file
- when it was entered into the archive; this will
- fail if the user is not the owner of the extracted
- file or the super-user.
-
- The _a_r utility exits 0 on success, and >0 if an error
- occurs.

- By default, _a_r writes archives that may be incompatible
- with historic archives, as the format used for storing
- archive members with names longer than fifteen characters
- has changed. This implementation of _a_r is backward com-
- patible with previous versions of _a_r in that it can read
- and write (using the -T option) historic archives. The -T
- option is provided for compatibility only, and will be
- deleted in a future release. See _a_r(5) for more informa-
- tion.

- The _a_r utility is expected to offer a superset of the
- POSIX 1003.2 functionality.
