NAME

       nomarch - extract `.arc' archives

SYNOPSIS

       nomarch [-hlptUv] [archive.arc] [match1 [match2 ... ]]

DESCRIPTION

       nomarch  lists, extracts, or tests `.arc' archives. (An alternate extension sometimes used
       was `.ark'; these work too.) This is a very outdated file format  which  should  certainly
       not  be  used  for anything new, but you may still need an extraction utility, and here it
       is. :-)

       The default action is to extract all files in the specified archive; see OPTIONS below for
       how to do other things instead.

OPTIONS

       -h     give terse usage help.

       -l     list  files  in  archive.  If  verbose listings are enabled, it shows the filename,
              compression method,  compressed/uncompressed  size,  date/time,  and  CRC;  but  by
              default, it just shows the filename, uncompressed size, and date/time.

       -p     extract to standard output, rather than to separate files.

       -t     test files in archive (more precisely, check file CRCs).

       -U     use uppercase filenames; more precisely, preserve original case from archive.

       -v     give verbose output (when used with `-l').

       archive.arc
              the archive to operate on.

       match1 etc.
              optionally  specify  which  archive members to list/extract/test. Those which match
              any of these filenames/wildcards are processed. Wildcard  operators  supported  are
              shell-like  `*'  and `?', but don't forget to quote arguments which use these (e.g.
              `nomarch foo.arc '*.bar'').

EXTRACTING MULTIPLE ARCHIVES

       nomarch follows the `unzip'-like practice of working on only one  archive  per  run,  with
       further  `filenames'  given  on  the command-line actually specifying files to extract (or
       whatever). The easiest way to work on multiple files with nomarch  is  simply  to  run  it
       multiple times using for; for example:

       for i in *.arc; do nomarch $i; done

       The above would extract all archives in the current directory.

USING THE PROGRAM FROM EMACS

       Emacs's  arc-mode  facility lets you work with various kinds of archive file directly from
       the editor. Making it use nomarch for extracting `.arc' files isn't too hard. Just add the
       following to your ~/.emacs file:

       (setq archive-arc-extract '("nomarch" "-U"))

BUGS

       The CRC used by the format is only 16-bit, so `-t' is a less-than-perfect test.

       One  compression  method, obsolete even by `.arc' standards :-), isn't supported yet. This
       is partly because I've yet to find a single file which uses it, despite testing  an  awful
       lot of files.

       Subdirectories in Spark archives are extracted as the `.arc'-format files they really are,
       which may not be terribly convenient.
