If the super-user employs this flag, the spool queue will 72be emptied entirely. 73.It Ar user 74Causes 75.Nm 76to attempt to remove any jobs queued belonging to that user 77(or users). This form of invoking 78.Nm 79is useful only to the super-user. 80.It Ar job\ \&# 81A user may dequeue an individual job by specifying its job number. 82This number may be obtained from the 83.Xr lpq 1 84program, e.g. 85.Pp 86.Bd -literal -offset indent 87\&% lpq \-l 88 891st:ken [job #013ucbarpa] 90 (standard input) 100 bytes 91% lprm 13 92.Ed 93.El 94.Pp 95If neither arguments or options are given, 96.Nm 97will delete the currently active job if it is 98owned by the user who invoked 99.Nm . 100.Pp 101.Nm 102announces the names of any files it removes and is silent if 103there are no jobs in the queue which match the request list. 104.Pp 105.Nm 106will kill off an active daemon, if necessary, before removing 107any spooling files. If 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 used 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/output/*/lock/ -compact 125.It Pa /etc/printcap 126Printer characteristics file. 127.It Pa /var/spool/output/* 128Spooling directories. 129.It Pa /var/spool/output/*/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.Dq Permission denied 135if the user tries to remove files other than his own. 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. 148
