zcmp, zdiff - compare compressed files
SYNOPSIS

DESCRIPTION

compare compressed files. Any options that are specified are passed to
cmp(1) or diff(1).
If only file1 is specified, it is compared against a file with the same
name, but with the extension removed. When both file1 or file2 are
specified, either file may be compressed.
Extensions handled by gzip(1):
o z, Z,
o gz,
o taz,
o tgz.
Extensions handled by bzip2(1):
o bz,
o bz2,
o tbz,
o tbz2.
Extensions handled by xz(1):
o lzma,
o xz,
o tlz,
o txz.
ENVIRONMENT

CAVEATS
zcmp and zdiff rely solely on the file extension to determine what is, or
is not, a compressed file. Consequently, the following are not supported
as arguments:
- directories
- device special files
- filenames indicating the standard input ("-")
