If 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). This form of invoking 75.Nm 76is useful only to the super-user. 77.It Ar job\ \&# 78A user may dequeue an individual job by specifying its job number. 79This number may be obtained from the 80.Xr lpq 1 81program, e.g.\& 82.Bd -literal -offset indent 83\&% lpq \-l 84 851st:ken [job #013ucbarpa] 86 (standard input) 100 bytes 87% lprm 13 88.Ed 89.El 90.Pp 91If neither arguments or options are given, 92.Nm 93will delete the currently active job if it is 94owned by the user who invoked 95.Nm . 96.Pp 97The 98.Nm 99utility announces the names of any files it removes and is silent if 100there are no jobs in the queue which match the request list. 101.Pp 102The 103.Nm 104utility will kill off an active daemon, if necessary, before removing 105any spooling files. If a daemon is killed, a new one is 106automatically restarted upon completion of file removals. 107.Sh ENVIRONMENT 108If the following environment variable exists, it is utilized by 109.Nm . 110.Bl -tag -width PRINTER 111.It Ev PRINTER 112If the environment variable 113.Ev PRINTER 114exists, 115and a printer has not been specified with the 116.Fl P 117option, 118the default printer is assumed from 119.Ev PRINTER . 120.El 121.Sh FILES 122.Bl -tag -width /var/spool/*/lock/ -compact 123.It Pa /etc/printcap 124Printer characteristics file. 125.It Pa /var/spool/* 126Spooling directories. 127.It Pa /var/spool/*/lock 128Lock file used to obtain the pid of the current 129daemon and the job number of the currently active job. 130.El 131.Sh DIAGNOSTICS 132``Permission denied" if the user tries to remove files other than his 133own. 134.Sh SEE ALSO 135.Xr lpq 1 , 136.Xr lpr 1 , 137.Xr lpd 8 138.Sh HISTORY 139The 140.Nm 141command appeared in 142.Bx 3.0 . 143.Sh BUGS 144Since there are race conditions possible in the update of the lock file, 145the currently active job may be incorrectly identified. 146
