#David Luyer <david_luyer@pacific.net.au> provides us with a similar |
| 4 |
|
|
#script in perl. Its attached. Run from /var/spool with $files = `echo mail/*` |
| 5 |
|
|
#or $files = result of building list from grep. No forks, execs, etc, etc, |
| 6 |
|
|
#so it can be run over a few hundred thousand mailboxes without too much pain, |
| 7 |
|
|
#although the locking is very ugly and doesn't actually test the lock. |
