[
.B \-l
] [
.B \-s
]
file1 file2
.SH DESCRIPTION
The two files are
compared.
(If
.I file1
is `\-',
the standard input is used.)
Under default options,
.I 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.
.PP
Options:
.TP 6
.B  \-l
Print the byte number (decimal) and the
differing bytes (octal) for each difference.
.TP 6
.B  \-s
Print nothing for differing files;
return codes only.
.dt
.SH "SEE ALSO"
diff(1), comm(1)
.SH DIAGNOSTICS
Exit code 0 is returned for identical
files, 1 for different files, and 2 for an
inaccessible or missing argument.
