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 This is a very outdated file format which should certainly not be used for anything new,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.
