cmp

CMP(1)								   User Commands							    CMP(1)

NAME

       cmp - compare two files byte by byte

SYNOPSIS

       cmp [OPTION]... FILE1 [FILE2 [SKIP1 [SKIP2]]]

DESCRIPTION

       Compare two files byte by byte.

       -b  --print-bytes
	      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.

       -s  --quiet  --silent
	      Output nothing; yield exit status only.

       -v  --version
	      Output version info.

       --help Output this help.

       SKIP1  and  SKIP2  are  the number of bytes to skip in each file.  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.
