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 one file is
specified, then it is compared to a file with the same name without the
.gz extension. 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.
When both files must be uncompressed before comparison, the second is
uncompressed to
/tmp. In all other cases,
zdiff and
zcmp
use only a pipe.

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