IAR(10.1)                                               IAR(10.1)

          iar - archive and library maintainer

          iar key [ posname ] afile [ file ... ]

          Iar maintains groups of files combined into a single archive
          file, afile. The main use of iar is to create and update
          library files for the loaders 2l(10.1), etc.  It can be
          used, though, for any similar purpose.

          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
               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 iar will create a new archive when
               afile does not exist, and give a warning.  Option c
               discards any old contents and suppresses the warning.

          l    Local.  Normally iar places its temporary files in the
               directory /tmp.  This option causes them to be placed
               in the local directory.

          When a d, r, or m key is specified and all members of the
          archive are valid object files for the same architecture,
          iar inserts a table of contents, required by the loaders, at
          the front of the library.  The table of contents is rebuilt
          whenever the archive is modified, except when the q key is
          specified or when the table of contents is explicitly moved
          or deleted.

          iar cr lib.a *.v
               Replace the contents of library `lib.a' with the object
               files in the current directory.

          /tmp/v*     temporaries


          2l(10.1), ar(10.6)

          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.
