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


SYNOPSIS
       xzcmp [option...]  file1 [file2]
       xzdiff ...
       lzcmp ...
       lzdiff ...


DESCRIPTION
       xzcmp  and  xzdiff  compare  uncompressed  contents  of  two files.  Uncompressed data and
       options are passed to cmp(1) or diff(1) unless --help or --version is specified.

       If both file1 and file2 are specified, they can be uncompressed files or files in  formats
       that  xz(1),  gzip(1), bzip2(1), lzop(1), zstd(1), or lz4(1) can decompress.  The required
       decompression commands are determined from the filename suffixes of file1  and  file2.   A
       file with an unknown suffix is assumed to be either uncompressed or in a format that xz(1)
       can decompress.

       If only one filename is provided, file1 must have a  suffix  of  a  supported  compression
       format  and  the  name for file2 is assumed to be file1 with the compression format suffix
       removed.

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


EXIT STATUS
       If a decompression error occurs, the exit status is  2.   Otherwise  the  exit  status  of
       cmp(1) or diff(1) is used.
