NAME
ar - archive and library maintainer (nar for cross-support)
SYNOPSIS
ar key [ posname ] afile name ...
nar 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. Note:
This version of ar uses an ASCII-format archive which is portable
among the various machines running Berkeley - derived versions of
UNIX.
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 position-
ing 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 direc-
tory.
FILES
/tmp/v* temporaries

CROSS-SUPPORT
In a cross-support environment, ar is called nar.
BUGS
If the same file is mentioned twice in an argument list, it may be
put in the archive twice.
