NAME
       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS
       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION
       xzcmp  and xzdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp(1) or diff(1).  If only one file is specified, then the files compared are file1 (which must have a suffix of  a  supported
       compression format) and file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp(1) or diff(1) is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO
       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS
       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
