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 or diff.  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 uncompressed if necessary and fed to cmp(1) or  diff(1).   The  exit
       status from cmp or diff 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.
