+.Sh NAME
+.Nm lprm
+.Nd remove jobs from the line printer spooling queue
+.Sh SYNOPSIS
+.Nm lprm
+.Op Fl P Ns Ar printer
+.Op Fl
+.Op job # ...
+.Op Ar user ...
+.Sh DESCRIPTION
+.Nm Lprm
+will remove a job, or jobs, from a printer's spool queue.
+Since the spooling directory is protected from users, using
+.Nm lprm
+is normally the only method by which a user may remove a job.
+The owner of a job is determined by the user's login name
+and host name on the machine where the
+.Xr lpr 1
+command was invoked.
+.Pp
+Options and arguments:
+.Bl -tag -width indent
+.It Fl P Ns Ar printer
+Specify the queue associated with a specific
+.Ar printer
+(otherwise the default printer is used).
+.It Fl
+If a single
+.Sq Fl
+is given,
+.Nm lprm
+will remove all jobs which a user
+owns.  If the super-user employs this flag, the spool queue will
+be emptied entirely.
+.It Ar user
+Causes
+.Nm lprm
+to attempt to remove any jobs queued belonging to that user
+(or users).  This form of invoking
+.Nm lprm
+is useful only to the super-user.
+.It Ar job\ \&#
+A user may dequeue an individual job by specifying its job number.
+This number may be obtained from the
+.Xr lpq  1
+program, e.g.
+.Pp
+.Bd -literal -offset indent
+\&% lpq \-l
+
+1st:ken				[job #013ucbarpa]
+	(standard input)	100 bytes
+% lprm 13
+.Ed
+.El
+.Pp
+If neither arguments or options are given,
+.Nm Lprm
+will delete the currently active job if it is
+owned by the user who invoked
+.Nm lprm  .
+.Pp
+.Nm 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.
+.Pp
+.Nm 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.
+.Sh ENVIRONMENT
+If the following environment variable exists, it is utilized by
+.Nm lprm .
+.Bl -tag -width PRINTER
+.It Ev PRINTER
+If the environment variable
+.Ev PRINTER
+exists,
+and a printer has not been specified with the
+.Fl P
+option,
+the default printer is assumed from 
+.Ev PRINTER .
+.El
+.Sh FILES
+.Bl -tag -width /var/spool/*/lock/ -compact
+.It Pa /etc/printcap
+Printer characteristics file.
+.It Pa /var/spool/*
+Spooling directories.
+.It Pa /var/spool/*/lock
+Lock file used to obtain the pid of the current
+daemon and the job number of the currently active job.
+.El
+.Sh SEE ALSO
+.Xr lpr 1 ,
+.Xr lpq 1 ,
+.Xr lpd 8
+.Sh DIAGNOSTICS
+.Dq Permission denied
+if the user tries to remove files other than his own.
+.Sh BUGS
+Since there are race conditions possible in the update of the lock file,
+the currently active job may be incorrectly identified.
+.Sh HISTORY
+The
+.Nm lprm
+command appeared in
+.Bx 3.0 .
