ZDIFF(1)		FreeBSD	General	Commands Manual		      ZDIFF(1)

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 spec-
     ified, 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
     TMPDIR  Directory in which	to place temporary files.  If unset, /tmp is
	     used.

FILES
     /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 ("-")
