lprm(1)lprm(1)Namelprm - remove jobs from line printer queue
Syntaxlprm [-Pprinter] [-] [job #...] [user...]
Description
The command removes a job, or jobs, from a printer's spool queue.
Since the spooling directory is protected from users, using is normally
the only method by which a user may remove a job.
The command without any arguments deletes the currently active job if
it is owned by the user who invoked
If the - flag is specified, removes all jobs which a user owns. If the
super-user employs this flag, the spool queue is emptied entirely. The
owner is determined by the user's login name and host name on the
machine where the command was invoked.
Specifying a user's name, or list of user names, causes to attempt to
remove any jobs queued belonging to that user (or users). This form of
invoking is useful only to the super-user.
A user may dequeue an individual job by specifying its job number.
This number may be obtained from the program. For example,
% lpq -l
1st: ken [job #013ucbarpa]
(standard input) 100 bytes
% lprm 13
The command announces the names of any files it removes and is silent
if there are no jobs in the queue which match the request list.
The command kills 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.
Options
- Removes all jobs owned by you only.
-P printer Removes jobs from specified printer. It may be
used to specify the queue associated with a spe‐
cific printer (otherwise the default printer, or
the value of the PRINTER variable in the environ‐
ment is used).
Restrictions
Since there are race conditions possible in the update of the lock
file, the currently active job may be incorrectly identified.
Diagnostics
``Permission denied" if the user tries to remove files other than his
own.
Files
/etc/printcap printer characteristics file
/usr/spool/* spooling directories
/usr/spool/*/lock lock file used to obtain the pid of the current
daemon and the job number of the currently active job
