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(3HEAD). The archive symbol table (de-
       scribed in ar(3HEAD)) is	used by	the link editor	ld(1) to effect	multi-
       ple  passes  over  libraries of object files in an efficient manner. An
       archive 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 will force
       the symbol table	to be rebuilt.

OPTIONS
       The following options are supported:

       -a    Positions new files in archive after the file named by  the  pos-
	     name operand.

       -b    Positions	new files in archive before the	file named by the pos-
	     name operand.

       -c    Suppresses	the diagnostic message that is written to standard er-
	     ror 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  pre-
	     vent truncated file names from replacing files with the same pre-
	     fix.

       -d    Deletes one or more files from archive.

       -i    Positions new files in archive before the file named by the  pos-
	     name operand (equivalent to -b).

       -m    Moves files. If -a, -b, or	-i with	the posname operand are	speci-
	     fied, moves files to the new position; otherwise, 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 will be
	     written 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 will be created and a diagnostic message will be
	     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 will	not change the
	     order of the archive. If the -u option is used with  the  -r  op-
	     tion, then	only those files with dates of modification later than
	     the archive files are replaced. If	the -a,	-b, or	-i  option  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	the new	files are placed at the	end.

       -s    Forces the	regeneration of	the archive symbol table even if ar is
	     not invoked with a	option which 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.

       -t    Prints a table of contents	of archive. The	files specified	by the
	     file  operands  will  be included in the written list. If no file
	     operands are specified, all files in archive will be 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; a di-
	     agnostic message will be written and the file  will  not  be  ex-
	     tracted.

       -u    Updates  older files.  When used with the -r option, files	within
	     archive will be 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.

       -V    Prints its	version	number on standard error.

   /usr/bin/ar
       -v    Gives verbose output. When	used with the  option  characters  -d,
	     -r,  or -x, writes	a detailed file-by-file	description of the ar-
	     chive creation and	the constituent	files, and maintenance	activ-
	     ity.  When	used with -p, writes the name of the file to the stan-
	     dard output before	writing	the file itself	to the	standard  out-
	     put.  When	 used  with -t,	includes a long	listing	of information
	     about the files within the	archive. When used with	-x, prints the
	     filename preceding	each extraction. When writing to an archive, a
	     message is	written	to the standard	error.

   /usr/xpg4/bin/ar
       -v    Same as /usr/bin/ar version, except when writing to  an  archive,
	     no	message	is written to the standard error.

       -x    Extracts  the  files named	by the file operands from archive. The
	     contents of archive will not be changed.  If no file operands are
	     given,  all  files	in archive will	be 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 un-
	     defined. The modification time of each file extracted will	be set
	     to	the time file is extracted from	archive.

OPERANDS
       The following operands are supported:

       archive
	     A path name of the	archive	file.

       file  A	path name. Only	the last component will	be used	when comparing
	     against the names of files	in the archive.	If two	or  more  file
	     operands  have  the same last path	name component ( 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.

       posname
	     The name of a file	in the archive file, used for  relative	 posi-
	     tioning; see options -m and -r.

ENVIRONMENT VARIABLES
       See  environ(5) for descriptions	of the following environment variables
       that affect the execution of ar:	LC_CTYPE, LC_MESSAGES, and NLSPATH.

EXIT STATUS
       The following exit values are returned:

       0     Successful	completion.

       >0    An	error occurred.
