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.
