34.Sh NAME
35.Nm lprm
36.Nd remove jobs from the line printer spooling queue
37.Sh SYNOPSIS
38.Nm
39.Op Fl P Ns Ar printer
40.Op Fl
41.Op job # ...\&
42.Op Ar user ...\&
43.Sh DESCRIPTION
44The
45.Nm
46utility will remove a job, or jobs, from a printer's spool queue.
47Since the spooling directory is protected from users, using
48.Nm
49is normally the only method by which a user may remove a job.
50The owner of a job is determined by the user's login name
51and host name on the machine where the
52.Xr lpr 1
53command was invoked.
54.Pp
55Options and arguments:
56.Bl -tag -width indent
57.It Fl P Ns Ar printer
58Specify the queue associated with a specific
59.Ar printer
60(otherwise the default printer is used).
61.It Fl
62If a single
63.Sq Fl
64is given,
65.Nm
66will remove all jobs which a user
67owns.
68If the super-user employs this flag, the spool queue will
69be emptied entirely.
70.It Ar user
71Cause
72.Nm
73to attempt to remove any jobs queued belonging to that user
74(or users).
75This form of invoking
76.Nm
77is useful only to the super-user.
78.It Ar job\ \&#
79A user may dequeue an individual job by specifying its job number.
80This number may be obtained from the
81.Xr lpq 1
82program, e.g.\&
83.Bd -literal -offset indent
84\&% lpq \-l
85
861st:ken				[job #013ucbarpa]
87	(standard input)	100 bytes
88% lprm 13
89.Ed
90.El
91.Pp
92If neither arguments or options are given,
93.Nm
94will delete the currently active job if it is
95owned by the user who invoked
96.Nm .
97.Pp
98The
99.Nm
100utility announces the names of any files it removes and is silent if
101there are no jobs in the queue which match the request list.
102.Pp
103The
104.Nm
105utility will kill off an active daemon, if necessary, before removing
106any spooling files.
107If a daemon is killed, a new one is
108automatically restarted upon completion of file removals.
109.Sh ENVIRONMENT
110If the following environment variable exists, it is utilized by
111.Nm .
112.Bl -tag -width PRINTER
113.It Ev PRINTER
114If the environment variable
115.Ev PRINTER
116exists,
117and a printer has not been specified with the
118.Fl P
119option,
120the default printer is assumed from
121.Ev PRINTER .
122.El
123.Sh FILES
124.Bl -tag -width /var/spool/*/lock/ -compact
125.It Pa /etc/printcap
126Printer characteristics file.
127.It Pa /var/spool/*
128Spooling directories.
129.It Pa /var/spool/*/lock
130Lock file used to obtain the pid of the current
131daemon and the job number of the currently active job.
132.El
133.Sh DIAGNOSTICS
134``Permission denied" if the user tries to remove files other than his
135own.
136.Sh SEE ALSO
137.Xr lpq 1 ,
138.Xr lpr 1 ,
139.Xr lpd 8
140.Sh HISTORY
141The
142.Nm
143command appeared in
144.Bx 3.0 .
145.Sh BUGS
146Since there are race conditions possible in the update of the lock file,
147the currently active job may be incorrectly identified.
