       Zcmp - decompress and compare two files byte by byte


       zcmp [options] file1 [file2]


       Zcmp  compares  two  files ("-" means standard input), and if they differ, tells the first
       byte and line number where they differ. Bytes and lines are numbered starting with  1.  If
       any  given  file  is  compressed,  its  uncompressed content is used. Compressed files are
       uncompressed on the fly; no temporary files are created.  The  supported  compressors  are
       bzip2, gzip, lzip and xz.

       Compares <file1> to <file2>. If <file2> is omitted zcmp tries the following: If <file1> is
       compressed, compares <file1> to the file with the  corresponding  decompressed  file  name
       (removes  the  extension from <file1>).  If <file1> is not compressed, compares <file1> to
       the uncompressed contents of <file1>.[bz2|gz|lz|xz] (the first one that is found).  If  no
       suitable file is found, compares <file1> to data read from standard input.

       Exit status is 0 if inputs are identical, 1 if different, 2 if trouble.


       -h, --help
              display this help and exit

       -V, --version
              output version information and exit

       -b, --print-bytes
              print differing bytes

       -i, --ignore-initial=<n>[,<n2>]
              ignore differences in the first <n> bytes

       -l, --list
              list position, value of all differing bytes

       -n, --bytes=<n>
              compare at most <n> bytes

       -q, --quiet
              suppress all messages

       -s, --silent
              (same as --quiet)

       -v, --verbose
              verbose mode (same as --list)

       Numbers may be followed by a multiplier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 = 1024, M =
       10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...
