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 files compressed via
gzip.
All options specified are passed directly to
cmp
or
diff.
If only
file1
is specified, it is compared to the uncompressed contents of
file1.gz.
If two files are specified, their contents (uncompressed if necessary) are fed to
cmp
or
diff.
The input files are not modified.
The exit status from
cmp
or
diff
is preserved.

BUGS
Messages from the
cmp
or
diff
programs may refer to file names such as "-" instead of to the file
names specified.
