.Sh NAME
|
|
.Nm lprm
|
|
.Nd remove jobs from the line printer spooling queue
|
|
.Sh SYNOPSIS
|
|
.Nm lprm
|
|
.Op Fl P Ns Ar printer
|
|
.Op Fl
|
|
.Op job # ...
|
|
.Op Ar user ...
|
|
.Sh DESCRIPTION
|
|
.Nm Lprm
|
|
will remove a job, or jobs, from a printer's spool queue.
|
|
Since the spooling directory is protected from users, using
|
|
.Nm lprm
|
|
is normally the only method by which a user may remove a job.
|
|
The owner of a job is determined by the user's login name
|
|
and host name on the machine where the
|
|
.Xr lpr 1
|
|
command was invoked.
|
|
.Pp
|
|
Options and arguments:
|
|
.Bl -tag -width indent
|
|
.It Fl P Ns Ar printer
|
|
Specify the queue associated with a specific
|
|
.Ar printer
|
|
(otherwise the default printer is used).
|
|
.It Fl
|
|
If a single
|
|
.Sq Fl
|
|
is given,
|
|
.Nm lprm
|
|
will remove all jobs which a user
|
|
owns. 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.

|
|
.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.
