10

DESCRIPTION

12       Compare two files byte by byte.
13
14       The optional SKIP1 and SKIP2 specify the number of bytes to skip at the
15       beginning of each file (zero by default).
16
17       Mandatory arguments to long options are  mandatory  for  short  options
18       too.
19
20       -b, --print-bytes
21              print differing bytes
22
23       -i, --ignore-initial=SKIP
24              skip first SKIP bytes of both inputs
25
26       -i, --ignore-initial=SKIP1:SKIP2
27              skip first SKIP1 bytes of FILE1 and first SKIP2 bytes of FILE2
28
29       -l, --verbose
30              output byte numbers and differing byte values
31
32       -n, --bytes=LIMIT
33              compare at most LIMIT bytes
34
35       -s, --quiet, --silent
36              suppress all normal output
37
38       --help display this help and exit
39
40       -v, --version
41              output version information and exit
42
43       SKIP  values  may be followed by the following multiplicative suffixes:
44       kB 1000, K  1024,  MB  1,000,000,  M  1,048,576,  GB  1,000,000,000,  G
45       1,073,741,824, and so on for T, P, E, Z, Y.
46
47       If  a FILE is '-' or missing, read standard input.  Exit status is 0 if
48       inputs are the same, 1 if different, 2 if trouble.
