gzcmp, gzdiff - compare compressed files
gzcmp [ cmp_options ] file1 [ file2 ]
gzdiff [ diff_options ] file1 [ file2 ]
Gzcmp and gzdiff 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.
cmp(1), diff(1), gzmore(1), gzgrep(1), gznew(1), gzforce(1), gzip(1),
Messages from the cmp or diff programs refer to temporary filenames
instead of those specified.
