LPRM(1)			  BSD General Commands Manual		       LPRM(1)

     lprm -- remove jobs from the line printer spooling	queue

     lprm [-] [-P printer] [-w maxwait]	[job# ...] [user ...]

     lprm will remove a	job, or	jobs, from a printer's spool queue.  Since the
     spooling directory	is protected from users, using lprm is normally	the
     only method by which a user may remove a job.  The	owner of a job is de-
     termined by the user's login name and host	name on	the machine where the
     lpr(1) command was	invoked.

     Options and arguments:

	     Specify the queue associated with a specific printer (otherwise
	     the default printer is used).

     -w	maxwait
	     Specify the maximum time to wait in seconds for remote responses.
	     The default is 300	seconds	or 5 minutes.

     -	     If	a single `-' is	given, lprm will remove	all jobs which a user
	     owns.  If the super-user employs this flag, the spool queue will
	     be	emptied	entirely.

     user    Causes lprm to attempt to remove any jobs queued belonging	to
	     that user (or users).  This form of invoking lprm is useful only
	     to	the super-user.

     job #   A user may	dequeue	an individual job by specifying	its job	num-
	     ber.  This	number may be obtained from the	lpq(1) program,	e.g.

		   % lpq -l

		   1st:ken			   [job	#013ucbarpa]
			   (standard input)	   100 bytes
		   % lprm 13

     If	neither	arguments or options are given,	lprm will delete the currently
     active job	if it is owned by the user who invoked lprm.

     lprm announces the	names of any files it removes and is silent if there
     are no jobs in the	queue which match the request list.

     lprm will kill off	an active daemon, if necessary,	before removing	any
     spooling files.  If a daemon is killed, a new one is automatically
     restarted upon completion of file removals.

     If	the following environment variable exists, it is used by lprm.

     PRINTER  If the environment variable PRINTER exists, and a	printer	has
	      not been specified with the -P option, the default printer is
	      assumed from PRINTER.

     /etc/printcap		Printer	characteristics	file.
     /var/spool/output/*	Spooling directories.
     /var/spool/output/*/lock	Lock file used to obtain the pid of the	cur-
				rent daemon and	the job	number of the cur-
				rently active job.

     "Permission denied" if the	user tries to remove files other than his own.

     lpq(1), lpr(1), lpd(8)

     The lprm command appeared in 3.0BSD.

     Since there are race conditions possible in the update of the lock	file,
     the currently active job may be incorrectly identified.
