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

     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.
