AR(1)AR(1)NAMEar - archive maintainer
SYNOPSISar key [ posname ] afile [ file ... ]
DESCRIPTION
Ar maintains groups of files combined into a single archive file,
afile. The main use of ar is to produce and manipulate UNIX archive
files, for instance to create program packages for Debian Linux. Note
that only iar(10.1) can manage archives used as object file libraries
by the Inferno and Plan 9 loaders.
Key is one character from the set drqtpmx, optionally concatenated with
one or more of vuaibclo. The files are constituents of the archive
afile. The meanings of the key characters are:
d Delete files from the archive file.
r Replace files in the archive file, or add them if missing.
Optional modifiers are
u Replace only files with modified dates later than that of
the archive.
a Place new files after posname in the archive rather than
at the end.
b or i Place new files before posname in the archive.
q Quick. Append files to the end of the archive without checking
for duplicates. Avoids quadratic behavior in
t List a table of contents of the archive. If names are given,
only those files are listed.
p Print the named files in the archive.
m Move the named files to the end or elsewhere, specified as with
o Preserve the access and modification times of files extracted
with the x command.
x Extract the named files. If no names are given, all files in
the archive are extracted. In neither case does x alter the ar‐
chive file.
v Verbose. Give a file-by-file description of the making of a new
archive file from the old archive and the constituent files.
With p, precede each file with a name. With t, give a long
listing of all information about the files, somewhat like a
listing by ls(1), showing
mode uid/gid size date name
c Create. Normally ar will create a new archive when afile does
not exist, and give a warning. Option c discards any old con‐
tents and suppresses the warning.
EXAMPLEar cr arch.a manifest *.tar.gz
Replace the contents of with the manifest file and all the
gzip(1)'d tar files in the current directory.

BUGS
If the same file is mentioned twice in an argument list, it may be put
in the archive twice.
The file format used by this command is taken from UNIX, and makes some
invalid assumptions, for instance that user IDs are numeric.
