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. AUTHOR
