          Print differing bytes.

     -i SKIP  --ignore-initial=SKIP
          Skip the first SKIP bytes of input.

     -i SKIP1:SKIP2  --ignore-initial=SKIP1:SKIP2

          Skip the first SKIP1 bytes of FILE1 and the first SKIP2
          bytes of FILE2.

     -l  --verbose
          Output byte numbers and values of all differing  bytes.

     -n LIMIT  --bytes=LIMIT
          Compare at most LIMIT bytes.

     SKIP1  and  SKIP2  are  the  number of bytes to skip in each
     file.  SKIP values may be followed by the  following  multi-
     plicative  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 sta-
     tus is 0 if inputs are the same, 1 if different, 2 if  trou-
     ble.
