NAME
zcmp, zdiff - compare compressed files
SYNOPSIS
zcmp [ cmp_options ] file1 [ file2 ]
zdiff [ diff_options ] file1 [ file2 ]
DESCRIPTION
Zcmp and zdiff are used to invoke
the cmp or the diff program on compressed files. All
options specified are passed directly to cmp or diff.
If only 1 file is specified, then the files compared are
file1 and an uncompressed file1.gz. If two files are
specified, then they are uncompressed if necessary and fed to
cmp or diff. The exit status from cmp or
diff is preserved.
SEE ALSO

znew(1),
zforce(1),
gzip(1),

BUGS
Messages from the cmp or diff programs
refer to temporary filenames instead of those specified.
