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
Exit code 0 is returned for identical files, 1 for different files, and
2 for an inaccessible or missing argument.
