If the super-user employs this flag, the spool queue will +be emptied entirely. +.It Ar user +Causes +.Nm lprm +to attempt to remove any jobs queued belonging to that user +(or users). This form of invoking +.Nm lprm +is useful only to the super-user. +.It Ar job\ \&# +A user may dequeue an individual job by specifying its job number. +This number may be obtained from the +.Xr lpq 1 +program, e.g. +.Pp +.Bd -literal -offset indent +\&% lpq \-l + +1st:ken [job #013ucbarpa] + (standard input) 100 bytes +% lprm 13 +.Ed +.El +.Pp +If neither arguments or options are given, +.Nm Lprm +will delete the currently active job if it is +owned by the user who invoked +.Nm lprm . +.Pp +.Nm Lprm +announces the names of any files it removes and is silent if +there are no jobs in the queue which match the request list. +.Pp +.Nm Lprm +will kill off an active daemon, if necessary, before removing +any spooling files. If a daemon is killed, a new one is +automatically restarted upon completion of file removals. +.Sh ENVIRONMENT +If the following environment variable exists, it is utilized by +.Nm lprm . +.Bl -tag -width PRINTER +.It Ev PRINTER +If the environment variable +.Ev PRINTER +exists, +and a printer has not been specified with the +.Fl P +option, +the default printer is assumed from +.Ev PRINTER . +.El +.Sh FILES +.Bl -tag -width /var/spool/*/lock/ -compact +.It Pa /etc/printcap +Printer characteristics file. +.It Pa /var/spool/* +Spooling directories. +.It Pa /var/spool/*/lock +Lock file used to obtain the pid of the current +daemon and the job number of the currently active job. +.El +.Sh SEE ALSO +.Xr lpr 1 , +.Xr lpq 1 , +.Xr lpd 8 +.Sh DIAGNOSTICS +``Permission denied" if the user tries to remove files other than his +own. +.Sh BUGS +Since there are race conditions possible in the update of the lock file, +the currently active job may be incorrectly identified. +.Sh HISTORY +The +.Nm lprm +command appeared in +.Bx 3.0 . diff --git a/usr.sbin/lpr/lprm/lprm.c b/usr.sbin/lpr/lprm/lprm.c new file mode 100644 index 0000000..20c4ee7 --- /dev/null +++ b/usr.sbin/lpr/lprm/lprm.c @@ -0,0 +1,144 @@ +/* + * Copyright (c) 1983, 1993 + * The Regents of the University of California.
