If the super-user employs this flag, the spool queue will 80be emptied entirely. 81.It Ar user 82Causes 83.Nm 84to attempt to remove any jobs queued belonging to that user 85(or users). This form of invoking 86.Nm 87is useful only to the super-user. 88.It Ar job\ \&# 89A user may dequeue an individual job by specifying its job number. 90This number may be obtained from the 91.Xr lpq 1 92program, e.g. 93.Pp 94.Bd -literal -offset indent 95\&% lpq \-l 96 971st:ken [job #013ucbarpa] 98 (standard input) 100 bytes 99% lprm 13 100.Ed 101.El 102.Pp 103If neither arguments or options are given, 104.Nm 105will delete the currently active job if it is 106owned by the user who invoked 107.Nm "" . 108.Pp 109.Nm 110announces the names of any files it removes and is silent if 111there are no jobs in the queue which match the request list. 112.Pp 113.Nm 114will kill off an active daemon, if necessary, before removing 115any spooling files. If a daemon is killed, a new one is 116automatically restarted upon completion of file removals. 117.Sh ENVIRONMENT 118If the following environment variable exists, it is utilized by 119.Nm "" . 120.Bl -tag -width PRINTER 121.It Ev PRINTER 122If the environment variable 123.Ev PRINTER 124exists, 125and a printer has not been specified with the 126.Fl P 127option, 128the default printer is assumed from 129.Ev PRINTER . 130.El 131.Sh FILES 132.Bl -tag -width /var/spool/output/*/lock/ -compact 133.It Pa /etc/printcap 134Printer characteristics file. 135.It Pa /var/spool/output/* 136Spooling directories. 137.It Pa /var/spool/output/*/lock 138Lock file used to obtain the pid of the current 139daemon and the job number of the currently active job. 140.El 141.Sh DIAGNOSTICS 142.Dq Permission denied 143if the user tries to remove files other than his own. 144.Sh SEE ALSO 145.Xr lpq 1 , 146.Xr lpr 1 , 147.Xr lpd 8 148.Sh HISTORY 149The 150.Nm 151command appeared in 152.Bx 3.0 . 153.Sh BUGS 154Since there are race conditions possible in the update of the lock file, 155the currently active job may be incorrectly identified. 156
