| 6 | # directly to cmp or diff. If only 1 file is specified, then | |
| 7 | # the files compared are file1 and an uncompressed file1.gz. | |
| 8 | # If two files are specified, then they are uncompressed (if | |
| 9 | # necessary) and fed to cmp or diff. The exit status from cmp | |
| 10 | # or diff is preserved. | |
