nomarch - extract .arc archives
nomarch [-hlptUv] [archive.arc] [match1 [match2 ... ]]
nomarch lists, extracts, or tests .arc archives. (An alternate exten
sion sometimes used was .ark; these work too.) This is a very out
dated 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.
-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
-v give verbose output (when used with -l).
the archive to operate on.
optionally specify which archive members to list/extract/test.
Those which match any of these filenames/wildcards are pro
cessed. Wildcard operators supported are shell-like * and ?,
but dont 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
Emacss arc-mode facility lets you work with various kinds of archive
file directly from the editor. Though it defaults to using the old non-
free arc program at the time of writing, making it use nomarch for
extracting .arc files isnt too hard. Just add the following to your
(setq archive-arc-extract ("nomarch" "-U"))
The CRC used by the format is only 16-bit, so -t is a less-than-per
One compression method, obsolete even by .arc standards :-), isnt
supported yet. This is partly because Ive 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.
