uucleanup

uucleanup(1M)															     uucleanup(1M)

NAME

       uucleanup - uucp spool directory clean-up

SYNOPSIS

       time] time] time] time] string] time] system] debug_level]

DESCRIPTION

       The commands, including are targeted for removal from HP-UX; see the below.

       scans  the  spool  directories  for old files and takes appropriate action to remove them.  Depending on the options selected, performs the
       following:

	      o  Informs the requestor of send and/or receive requests for systems that cannot be reached.

	      o  Returns mail that cannot be delivered to the sender.

	      o  Removes all other files.

       In addition, warns users of requestors who have been waiting for a given number of days (the default is 1 day).	Note that unless  time	is
       specifically set, the default time values for the following options are used.

   Options
       recognizes the following options:

	      Any	     files  greater or equal to time days old are removed with appropriate information to the requestor.  The default time
			     is 7 days.

	      Any	     files greater or equal to time days old are removed.  An attempt is made to deliver mail messages	and  execute  news
			     when appropriate.	The default time is 7 days.

	      Any	     files  equal  to time cause a message to be mailed to the requestor warning about the delay in contacting the remote.
			     The message includes the JOBID, and in the case of mail, the mail message.  The administrator can include	a  message
			     line telling who to call to correct the problem (see the option).	The default time is 1 day.

	      Any	     files  greater  than  or  equal  to time days old are removed.  The files are probably not present (if they were, the
			     could be executed).  But, if files are present, they are taken care of by processing.  The default time is 2 days.

	      This string is included in the warning message generated by the
			     option.  The default string is

	      Other files whose age is more than
			     time days are deleted.  The default time is 2 days.

	      Clean-up the spool directory for
			     system only.  The default is to clean-up all spool directories.

	      The debug level is a single digit between 0 and 9.
			     The higher the numbers, the more detailed the debugging information returned.

       This program is typically started by the script which should be started by (see cron(1M)).
