If the super-user employs this flag, the spool queue will 76be emptied entirely. 77.It Ar user 78Causes 79.Nm 80to attempt to remove any jobs queued belonging to that user 81(or users). This form of invoking 82.Nm 83is useful only to the super-user. 84.It Ar job\ \&# 85A user may dequeue an individual job by specifying its job number. 86This number may be obtained from the 87.Xr lpq 1 88program, e.g. 89.Pp 90.Bd -literal -offset indent 91\&% lpq \-l 92 931st:ken [job #013ucbarpa] 94 (standard input) 100 bytes 95% lprm 13 96.Ed 97.El 98.Pp 99If neither arguments or options are given, 100.Nm 101will delete the currently active job if it is 102owned by the user who invoked 103.Nm . 104.Pp 105.Nm 106announces the names of any files it removes and is silent if 107there are no jobs in the queue which match the request list. 108.Pp 109.Nm 110will kill off an active daemon, if necessary, before removing 111any spooling files. If a daemon is killed, a new one is 112automatically restarted upon completion of file removals. 113.Sh ENVIRONMENT 114If the following environment variable exists, it is used by 115.Nm . 116.Bl -tag -width PRINTER 117.It Ev PRINTER 118If the environment variable 119.Ev PRINTER 120exists, 121and a printer has not been specified with the 122.Fl P 123option, 124the default printer is assumed from 125.Ev PRINTER . 126.El 127.Sh FILES 128.Bl -tag -width /var/spool/output/*/lock/ -compact 129.It Pa /etc/printcap 130Printer characteristics file. 131.It Pa /var/spool/output/* 132Spooling directories. 133.It Pa /var/spool/output/*/lock 134Lock file used to obtain the pid of the current 135daemon and the job number of the currently active job. 136.El 137.Sh DIAGNOSTICS 138.Dq Permission denied 139if the user tries to remove files other than his own. 140.Sh SEE ALSO 141.Xr lpq 1 , 142.Xr lpr 1 , 143.Xr lpd 8 144.Sh HISTORY 145The 146.Nm 147command appeared in 148.Bx 3.0 . 149.Sh BUGS 150Since there are race conditions possible in the update of the lock file, 151the currently active job may be incorrectly identified. 152
