NAME
zcmp, zdiff - compare compressed files
SYNOPSIS
zcmp [options] file [file2]
zdiff [options] file [file2]
DESCRIPTION
zcmp and zdiff are filters that invoke cmp(1) or diff(1) respectively to
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

used.

/tmp/zcmp.XXXXXXXXXX Temporary file for zcmp.
/tmp/zdiff.XXXXXXXXXX Temporary file for zdiff.
SEE ALSO
bzip2(1), cmp(1), diff(1), gzip(1), xz(1)
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 ("-")
