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.
