CMP(1) CMP(1)
NAME
cmp - compare two files
SYNOPSIS
cmp [ -lsL ] file1 file2 [ offset1 [ offset2 ] ]
DESCRIPTION
The two files are compared. If the contents differ a diag-
nostic results, otherwise there is no output.
The options are:
l Print the byte number (decimal) and the differing bytes
(octal) for each difference.
s Print nothing for differing files, but set the return
code.
L Print the line number of the first differing byte.
If offsets are given, comparison starts at the designated
byte position of the corresponding file. Offsets that begin
with 0x are hexadecimal; with 0, octal; with anything else,
decimal.

DIAGNOSTICS
Cmp reports `EOF' and identifies the file if one file is
short. It reports the number of the first disagreeing byte
if contents differ. The return code is 0 for identical
files, 1 for different files, and 2 for an inaccessible or
missing argument.
