If the super-user employs this flag, the spool queue will 73be emptied entirely. 74.It Ar user 75Cause 76.Nm 77to attempt to remove any jobs queued belonging to that user 78(or users). This form of invoking 79.Nm 80is useful only to the super-user. 81.It Ar job\ \&# 82A user may dequeue an individual job by specifying its job number. 83This number may be obtained from the 84.Xr lpq 1 85program, e.g.\& 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 101The 102.Nm 103utility announces the names of any files it removes and is silent if 104there are no jobs in the queue which match the request list. 105.Pp 106The 107.Nm 108utility will kill off an active daemon, if necessary, before removing 109any spooling files. If a daemon is killed, a new one is 110automatically restarted upon completion of file removals. 111.Sh ENVIRONMENT 112If the following environment variable exists, it is utilized by 113.Nm . 114.Bl -tag -width PRINTER 115.It Ev PRINTER 116If the environment variable 117.Ev PRINTER 118exists, 119and a printer has not been specified with the 120.Fl P 121option, 122the default printer is assumed from 123.Ev PRINTER . 124.El 125.Sh FILES 126.Bl -tag -width /var/spool/*/lock/ -compact 127.It Pa /etc/printcap 128Printer characteristics file. 129.It Pa /var/spool/* 130Spooling directories. 131.It Pa /var/spool/*/lock 132Lock file used to obtain the pid of the current 133daemon and the job number of the currently active job. 134.El 135.Sh DIAGNOSTICS 136``Permission denied" if the user tries to remove files other than his 137own. 138.Sh SEE ALSO 139.Xr lpq 1 , 140.Xr lpr 1 , 141.Xr lpd 8 142.Sh HISTORY 143The 144.Nm 145command appeared in 146.Bx 3.0 . 147.Sh BUGS 148Since there are race conditions possible in the update of the lock file, 149the currently active job may be incorrectly identified. 150
