NAME

cmp − compare two files

SYNOPSIS

cmp [ −l ] [ −s ] file1 file2

DESCRIPTION

The two files are compared.  (If file1 is −, the standard input is used.)  Under default options, cmp makes no comment if the files are the same; if they differ, it announces the byte and line number at which the difference occurred.  If one file is an initial subsequence of the other, that fact is noted. 

OPTIONS

−l Print the byte number (decimal) and the differing bytes (octal) for each difference. 

−s Print nothing for differing files; return codes only. 

SEE ALSO

diff(1), comm(1)

DIAGNOSTICS

The following exit code is returned:

0for identical files,
1for different files,
2for an inaccessible or missing argument.
