SYNOPSIS

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

DESCRIPTION

       The  two  files are compared.  (If a file is `-', the standard input is
       used.)  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.  If skip1 or skip2 are given, the
       indicated number of bytes is read from each file before the  comparison
       starts.   The  skip  values may be either decimal or, if beginning with
       `0', 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.

       The following option is an extension:

       -w    For  each  difference, the surrounding 8-byte unit, measured from
             the beginning of the file, is printed for both files as a  64-bit
             MSB  integer  in  octal, and as a byte string, with non-ASCII and
             control characters replaced by an underscore.

DIAGNOSTICS

       Exit code 0 is returned for identical files, 1 for different  files,  2
       for an inaccessible or missing argument.
