If the super-user employs this flag, the spool queue will 71be emptied entirely. 72.It Ar user 73Causes 74.Nm lprm 75to attempt to remove any jobs queued belonging to that user 76(or users). This form of invoking 77.Nm lprm 78is useful only to the super-user. 79.It Ar job\ \&# 80A user may dequeue an individual job by specifying its job number. 81This number may be obtained from the 82.Xr lpq 1 83program, e.g. 84.Pp 85.Bd -literal -offset indent 86\&% lpq \-l 87 881st:ken [job #013ucbarpa] 89 (standard input) 100 bytes 90% lprm 13 91.Ed 92.El 93.Pp 94If neither arguments or options are given, 95.Nm Lprm 96will delete the currently active job if it is 97owned by the user who invoked 98.Nm lprm . 99.Pp 100.Nm Lprm 101announces the names of any files it removes and is silent if 102there are no jobs in the queue which match the request list. 103.Pp 104.Nm Lprm 105will kill off an active daemon, if necessary, before removing 106any spooling files. If a daemon is killed, a new one is 107automatically restarted upon completion of file removals. 108.Sh ENVIRONMENT 109If the following environment variable exists, it is utilized by 110.Nm lprm . 111.Bl -tag -width PRINTER 112.It Ev PRINTER 113If the environment variable 114.Ev PRINTER 115exists, 116and a printer has not been specified with the 117.Fl P 118option, 119the default printer is assumed from 120.Ev PRINTER . 121.El 122.Sh FILES 123.Bl -tag -width /var/spool/output/*/lock/ -compact 124.It Pa /etc/printcap 125Printer characteristics file. 126.It Pa /var/spool/output/* 127Spooling directories. 128.It Pa /var/spool/output/*/lock 129Lock file used to obtain the pid of the current 130daemon and the job number of the currently active job. 131.El 132.Sh SEE ALSO 133.Xr lpr 1 , 134.Xr lpq 1 , 135.Xr lpd 8 136.Sh DIAGNOSTICS 137.Dq Permission denied 138if the user tries to remove files other than his own. 139.Sh BUGS 140Since there are race conditions possible in the update of the lock file, 141the currently active job may be incorrectly identified. 142.Sh HISTORY 143The 144.Nm lprm 145command appeared in 146.Bx 3.0 . 147
