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

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

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

       -m	Moves  files.  If  -a,	-b, or -i with the posname operand are
		specified, the -m option moves files to	the new	position. Oth-
		erwise,	-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 written in the order of the	archive.

       -q	Quickly	 appends  files	to the end of archive. Positioning op-
		tions -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  ar-
		chive 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.
		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.

       -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.

       -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 archive are replaced only if the	corresponding file has
		a  modification	 time that is at least as new as the modifica-
		tion time of the file within archive.

       -V	Prints its version number on standard error.

   /usr/ccs/bin/ar
       -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  mainte-
		nance  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 ex-
		traction. When writing to an archive, -v writes	a  message  to
		the standard error.

   /usr/xpg4/bin/ar
       -v	Same as	the /usr/ccs/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 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 sup-
		ported in the directory	to which it is	being  extracted,  the
		results	 are undefined.	The modification time of each file ex-
		tracted	is 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 is used when  com-
		       paring  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 unspeci-
		       fied. 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	 rela-
		       tive positioning. See options -m	and -r.

ENVIRONMENT VARIABLES
       See  environ(5) 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 di-
		       rectory for temporary files, if any.

       TZ	       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.

EXIT STATUS
       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.

ATTRIBUTES
       See attributes(5) for descriptions of the following attributes:

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".

       When an archive file contains a member file whose class is ELF_CLASS64,
       archive	file  members may be padded so	    the	ELF_CLASS64 files will
       be placed in an 8-byte boundary.	Only the  ELF  object  files  will  be
       padded, if needed. The padding character	is "\n".
