NAME
       cmp - compare two files

SYNOPSIS
       cmp [ -l ] [ -s ] file1 file2 [ skip1 ] [ skip2 ]

DESCRIPTION
       The two files are compared.  If file1 is -, the standard input is
       used.  If file2 is -, the standard input is used.  If file1 and file2
       refer to standard input or refer to the same FIFO special, block
       special or character special file, the results are undefined.  Under
       default options, cmp makes no comment if the files are the same; if
       they differ, it announces the byte and line number at which the
       difference occurred.  If one file is an initial subsequence of the
       other, that fact is noted.  skip1 and skip2 are initial byte offsets
       into file1 and file2 respectively, and may be either octal or
       decimal; a leading 0 denotes octal.

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

        -s    Print nothing for differing files; return codes only.

DIAGNOSTICS
       The following exit values are returned:

       0      The files are identical.

       1      The files are different; this includes the case where one file
              is identical to the first part of the other.

       >1     An error occurred.
