Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl P Ns Ar printer
|
|
.Op Fl
|
|
.Op job # ...\&
|
|
.Op Ar user ...\&
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility will remove a job, or jobs, from a printer's spool queue.
|
|
Since the spooling directory is protected from users, using
|
|
.Nm
|
|
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
|
|
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
|
|
Cause
|
|
.Nm
|
|
to attempt to remove any jobs queued belonging to that user
|
|
(or users).
|
|
This form of invoking
|
|
.Nm
|
|
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.\&
|
|
.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
|
|
will delete the currently active job if it is
|
|
owned by the user who invoked
|
|
.Nm .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility 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
|
|
The
|
|
.Nm
|
|
utility 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 .
|
|
.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 DIAGNOSTICS
|
|
``Permission denied" if the user tries to remove files other than his
|
|
own.
|

|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
command appeared in
|
|
.Bx 3.0 .
|
|
.Sh BUGS
|
|
Since there are race conditions possible in the update of the lock file,
|
|
the currently active job may be incorrectly identified.
