XZDIFF(1)                          XZ Utils                          XZDIFF(1)

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.
