AR(1) AR(1) NAME ar - archive maintainer SYNOPSIS ar 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 con- catenated with one or more of vuaibclo. The files are con- stituents 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 miss- ing. 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 `for (i in *.v) ar r lib.a $i'. 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 `r'. 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 archive file. v Verbose. Give a file-by-file description of the making AR(1) AR(1) of a new archive file from the old archive and the con- stituent 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 contents and suppresses the warning. EXAMPLE ar cr arch.a manifest *.tar.gz Replace the contents of `arch.a' with the manifest file and all the gzip(1)'d tar files in the current direc- tory. FILES /tmp/art.*.* temporaries SOURCE /appl/cmd/ar.b SEE ALSO 2l(10.1), iar(10.1), ar(10.6) 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.
