.SH NAME
xzcmp, xzdiff, lzcmp, lzdiff \- compare compressed files
.SH SYNOPSIS
.B xzcmp
.RI [ cmp_options "] " file1 " [" file2 ]
.br
.B xzdiff
.RI [ diff_options "] " file1 " [" file2 ]

.B lzcmp

.SH DESCRIPTION
.B xzcmp
and
.B xzdiff
invoke
.BR cmp (1)
or
.BR diff (1)
on files compressed with
.BR xz (1),
.BR lzma (1),
.BR gzip (1),
.BR bzip2 (1),
.BR lzop (1),
or
.BR zstd (1).
All options specified are passed directly to
.BR cmp (1)
or
.BR diff (1).
If only one file is specified, then the files compared are
.I file1
(which must have a suffix of a supported compression format) and
.I file1
from which the compression format suffix has been stripped.
If two files are specified,
then they are uncompressed if necessary and fed to
.BR cmp (1)
or
.BR diff (1).
The exit status from
.BR cmp (1)
or
.BR diff (1)
is preserved unless a decompression error occurs; then exit status is 2.
.PP
The names
.B lzcmp
and
.B lzdiff
are provided for backward compatibility with LZMA Utils.
