| 7 # Bzcmp and bzdiff are used to invoke the cmp or the diff pro- | |
| 8 # gram on compressed files. All options specified are passed | |
| 9 # directly to cmp or diff. If only 1 file is specified, then | |
| 10 # the files compared are file1 and an uncompressed file1.gz. | |
| 11 # If two files are specified, then they are uncompressed (if | |
| 12 # necessary) and fed to cmp or diff. The exit status from cmp | |
| 13 # or diff is preserved. | |
