.SH DESCRIPTION
nomarch lists, extracts, or tests `.arc' archives. (An alternate
extension sometimes used was `.ark'; these work too.) This is a
.I 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outdated file format which should certainly not be used for anything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. :-)
.PP
The default action is to extract all files in the specified archive;
see
.B OPTIONS
below for how to do other things instead.
.\"
.\"------------------------------------------------------------------
.\"
.SH OPTIONS
.TP
.I -h
give terse usage help.
.TP
.I -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.
.TP
.I -p
extract to standard output, rather than to separate files.
.TP
.I -t
test files in archive (more precisely, check file CRCs).
.TP
.I -U
use uppercase filenames; more precisely, preserve original case from
archive.
.TP
.I -v
give verbose output (when used with
.RI ` -l ').
.TP
.B archive.arc
the archive to operate on.
.TP
.BR 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.
.RI ` nomarch
.IR "foo.arc '*.bar'" ').
.\"
.\"------------------------------------------------------------------
.\"
.SH "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
.IR for ;
for example:
.PP
for i in *.arc; do nomarch $i; done
.PP
The above would extract all archives in the current directory.
.\"
.\"------------------------------------------------------------------
.\"
.SH "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
.I "~/.emacs"
file:
.PP
(setq archive-arc-extract '("nomarch" "-U"))
.\"
.\"------------------------------------------------------------------
.\"
.SH BUGS
The CRC used by the format is only 16-bit, so
.RI ` -t '
is a less-than-perfect test.
.PP
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.
.PP
Subdirectories in Spark archives are extracted as the `.arc'-format
files they really are, which may not be terribly convenient.
