AR(1) General Commands Manual AR(1) NAME
ar - archive and library maintainer SYNOPSIS
ar key [ posname ] afile name ... DESCRIPTION
Ar maintains groups of files combined into a single archive file. Its main use is to create and update library files as used by the loader. It can be used, though, for any similar purpose. Key is one character from the set drqtpmx, optionally concatenated with one or more of vuaibcl. Afile is the archive file. The names are constituent files in the archive file. The meanings of the key characters are: d Delete the named files from the archive file. r Replace the named files in the archive file. If the optional character u is used with r, then only those files with modified dates later than the archive files are replaced. If an optional positioning character from the set abi is used, then the posname argument must be present and specifies that new files are to be placed after (a) or before (b or i) posname. Otherwise new files are placed at the end. q Quickly append the named files to the end of the archive file. Optional positioning characters are invalid. The command does not check whether the added members are already in the archive. Useful only to avoid quadratic behavior when creating a large archive piece-by-piece. t Print a table of contents of the archive file. If no names are given, all files in the archive are tabled. If names are given, only those files are tabled. p Print the named files in the archive. m Move the named files to the end of the archive. If a positioning character is present, then the posname argument must be present and, as in r, specifies where the files are to be moved. x Extract the named files. If no names are given, all files in the archive are extracted. In neither case does x alter the archive file. v Verbose. Under the verbose option, ar gives a file-by-file description of the making of a new archive file from the old archive and the constituent files. When used with t, it gives a long listing of all information about the files. When used with p, it precedes each file with a name. c Create. Normally ar will create afile when it needs to. The create option suppresses the normal message that is produced when afile is created. l Local. Normally ar places its temporary files in the directory /tmp. This option causes them to be placed in the local directory. FILES

If the same file is mentioned twice in an argument list, it may be put in the archive twice. AR(1)

ar(1) General Commands Manual ar(1) Name ar - archive and library maintainer Syntax ar option [ posname ] archive file ... Description The archiver ar maintains groups of files as a single archive file. This utility is generally used to create and update library files that the link editor uses; however, you can use the archiver for other similar purposes. This version uses a portable ASCII-format archive that you can use on various machines that run UNIX. If you have an archive that uses an older format, see Options This section describes the options and suboptions that you can use with the ar utility. Suboptions must be specified with options. Fol- lowing is a list and description of the options: d Deletes the specified files from the archive file. r Replaces the specified files in the archive file. If you use the suboption u with r, the archiver only replaces those files that have last-modified dates later than the archive files. If you use a positioning character (from the set abi) you must specify the posname argument to tell the archiver to put the new files after (a) or before (b or i). Otherwise, the archiver puts new files at the end of the archive. q Appends the specified files to the end of the archive file. The archiver does not accept suboption positioning characters with the q option. It also does not check whether the files you want to add already exist in the archive. Use the q option only to avoid quadratic behavior when you create a large archive piece by piece. t Prints a table of contents for the files in the archive file. If you do not specify any filenames, the archiver builds a table of contents for all files. If you specify filenames, the archiver builds a table of contents only for those files. p Prints the specified files from the archive. m Moves the specified files to the end of the archive. If you specify a positioning character, you must also specify the posname (as in option r) to tell the archiver where to move the files. x Extracts the specified files from the archive. If you do not specify any filenames, the archiver extracts all files. When it extracts files, the archiver does not change any file. Normally, the last-modified date for each extracted file shows the date when someone extracted it; however, when you use o, the archiver resets the last-modified date to the date recorded in the archive. s Makes a symbol definition (symdef file) as the first file of an archive. This file contains a hash table of ranlib structures and a corresponding string table. The symdef file's name is based on the byte ordering of the hash table and the byte ordering of the file's target machine. Files must be consistent in their target byte ordering before the archiver can create a symdef file. If you change the archive contents, the symdef file becomes obsolete because the archive file's name changes. If you specify s, the archiver creates the symdef file as its last action before finishing execution. You must specify at least one other archive option (m, p, q, r, or t) when you use the s option. For UMIPS-V, archives include member objects based on the definition of a common object only. For UMIPS-BSD, they define the common object, but do not include the object. v Gives a file-by-file description as the archiver makes a new archive file from an old archive and its constituent files. When you use this option with t, the archiver lists all information about the files in the archive. When you use this option with p, the archiver precedes each file with a name. c Suppresses the normal message that the archiver prints when it creates the specified archive file. Normally, the archiver creates the specified archiver file when it needs to. l Places temporary files in the local directory. If the l option is not used then the value of the environment symbol, TMPDIR, is used as the directory for temporary files. If TMPDIR is not defined or if the directory it references is not writable then /tmp is used. The suboptions do these things: a Specifies that the file goes after the existing file (posname). Use this suboption with the m or r options. b Specifies that the file goes before the existing file (posname). Use this suboption with the m or r options. i Specifies that the file goes before the existing file (posname). Use this suboption with the m or r options. o Forces a newly created file to have the last-modified date that it had before it was extracted from the archive. Use this suboption with the x option. u Prevents the archiver from replacing an existing file unless the replacement is newer than the existing file. This option uses the UNIX system last modified date for this comparison. Use this suboption with the r option. Restrictions If you specify the same file twice in an argument list, it can appear twice in the archive file. The o option does not change the last-modified date of a file unless you own the extracted file or you are the superuser. This command truncates filenames to 15 characters.
