nomarch lists/extracts/tests `.arc' archives. (It also handles `.ark'
files, they're exactly the same.) This is a *very* outdated file
format which should never be used for anything new, but unfortunately,
you can still run into it every so often (especially if you mess about
with old CP/M stuff). So nomarch is handy as a way to deal with these
files.
============================ R E Q U I R E M E N T ==========================
nomarch tested and worked fine on the following configurations:
- IcarOS i386 (Kickstart 51.51, Workbench 40.0, AROS ABIv0)
- AROS One i386 (Kickstart 51.51, Workbench 40.0, AROS ABIv0)
================================= U S A G E =================================
nomarch [-hlptUv] [archive.arc] [match1 [match2 ... ]]
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 (bash):
for i in *.arc; do nomarch $i; done
The above would extract all archives in the current directory.
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.
