uucleanup - uucp spool directory clean-up
/usr/lib/uucp/uucleanup [-Ctime] [-Dtime] [-mstring]
     [-otime] [-ssystem] [-Wtime] [-xdebug-level] [-Xtime]
uucleanup will scan the spool directories for old files and
    take appropriate action to remove them in a useful way:
  - o
- Inform the requester of send/receive requests for systems that can not be
      reached.
 
  - o
- Return undeliverable mail to the sender.
 
  - o
- Deliver rnews files addressed to the local system.
 
  - o
- Remove all other files.
 
In addition, there is a provision to warn users of requests that
    have been waiting for a given number of days (default 1 day). Note:
    uucleanup will process as if all option times were specified
    to the default values unless time is specifically set.
This program is typically started by the shell
    uudemon.cleanup, which should be started by cron(8).
-Ctime
Remove any C. files greater or equal to
  time days old and send appropriate information to the requester
  (default 7 days).
-Dtime
Remove any D. files greater or equal to
  time days old, make an attempt to deliver mail messages, and execute
  rnews when appropriate (default 7 days).
-mstring
Include string in the warning message generated by
  the -W option. The default line is "See your local administrator
  to locate the problem".
-otime
Delete other files whose age is more than time
  days (default 2 days).
-ssystem
Execute for system spool directory only.
-Wtime
Any C. files equal to time days old will
  cause a mail message to be sent to the requester warning about the delay in
  contacting the remote. The message includes the JOBID, and in the case
  of mail, the mail message. The administrator may include a message line
  telling whom to call to check the problem (-m option) (default 1
  day).
-xdebug-level
Produce debugging output on standard output.
  debug-level is a single digit between 0 and 9; higher numbers give more
  detailed debugging information. (This option may not be available on all
  systems.)
-Xtime
Any X. files greater or equal to time days
  old will be removed. The D. files are probably not present (if they
  were, the X. could get executed). But if there are D. files,
  they will be taken care of by D. processing (default 2 days).
