NAME
       cmp - compare two files byte by byte

SYNOPSIS
       cmp [OPTION]... FILE1 [FILE2 [SKIP1 [SKIP2]]]

DESCRIPTION
       Compare two files byte by byte.

       The  optional SKIP1 and SKIP2 specify the number of bytes to skip at the beginning of each
       file (zero by default).

       Mandatory arguments to long options are mandatory for short options too.

       -b, --print-bytes
	      print differing bytes

       -i, --ignore-initial=SKIP
	      skip first SKIP bytes of both inputs

       -i, --ignore-initial=SKIP1:SKIP2
	      skip first SKIP1 bytes of FILE1 and first SKIP2 bytes of FILE2

       -l, --verbose
	      output byte numbers and differing byte values

       -n, --bytes=LIMIT
	      compare at most LIMIT bytes

       -s, --quiet, --silent
	      suppress all normal output

       --help display this help and exit

       -v, --version
	      output version information and exit

       SKIP values may be followed by the following multiplicative suffixes: kB 1000, K 1024,  MB
       1,000,000, M 1,048,576, GB 1,000,000,000, G 1,073,741,824, and so on for T, P, E, Z, Y.

       If  a  FILE  is	'-'  or missing, read standard input.  Exit status is 0 if inputs are the
       same, 1 if different, 2 if trouble.
