XZDIFF(1)                           XZ Utils                           XZDIFF(1)

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

SYNOPSIS
     xzcmp [option...]  file1 [file2]
     xzdiff ...
     lzcmp ...  (DEPRECATED)
     lzdiff ...  (DEPRECATED)

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.  They are deprecated and will be removed in a future version.

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