NAME

	cmp – compare two files

SYNOPSIS

	cmp [ −lsL ] file1 file2 [ offset1 [ offset2 ] ]

DESCRIPTION

The two files are compared. A diagnostic results if the contents differ, otherwise there is no output. The options are: l     Print the byte number (decimal) and the differing bytes (hexadecimal) for each difference. s     Print nothing for differing files, but set the exit status. 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

	If a file is inaccessible or missing, the exit status is open. If the files are the same, the exit status is empty (true). If they are the same except that one is longer than the other, the exit status is EOF. Otherwise cmp reports the position of the first disagreeing byte and the exit status is differ.
