     CMP(1)                                                     CMP(1)

     NAME
          cmp - compare two files

     SYNOPSIS
          cmp [ -lsL ] file1 file2 [ offset1 [ offset2 ] ]

     DESCRIPTION
          The two files are compared.  A diagnostic results if the
          contents differ, otherwise there is no output.  By default,
          cmp prints the byte number of the first differing byte.

          The options are:

          -l   Print the byte number (decimal) and the differing bytes
               (hexadecimal) for each difference.

          -s   Print nothing for differing files, but set the exit
               status.

          -L   Print the line number of the first differing byte.

          If offsets are given, comparison starts at the designated
          byte position of the corresponding file.  Offsets that begin
          with 0x are hexadecimal; with 0, octal; with anything else,
          decimal.
