- NAME
- cmp - compare two files
-
- SYNTAX
- 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, comm
-
- DIAGNOSTICS
- Exit code 0 is returned for identical files, 1 for different
- files, and 2 for an inaccessible or missing argument.
-
- RESTRICTIONS
- Only one option may be specified at a time.
