6.  Uuclean - Uucp Spool Directory Cleanup

This program is typically started by the daemon, once a day. Its function is to remove files from the spool directory which are more than 3 days old. These are usually files for work which can not be completed.

The options available are:

-ddir
The directory to be scanned is dir.
-m
Send mail to the owner of each file being removed. (Note that most files put into the spool directory will be owned by the owner of the uucp programs since the setuid bit will be set on these programs. The mail will therefore most often go to the owner of the uucp programs.)
-nhours
Change the aging time from 72 hours to hours hours.
-ppre
Examine files with prefix pre for deletion. (Up to 10 file prefixes may be specified.)
-xnum
This is the level of debugging output desired.
