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.
