NAME
lprm - remove jobs from the line printer spooling queue SYNOPSIS
lprm [ -Pprinter ] [ - ] [ job # ... ] [ user ... ] DESCRIPTION
Lprm will remove a job, or jobs, from a printer's spool queue. Since the spooling directory is protected from users, using lprm is nor- mally the only method by which a user may remove a job. Lprm without any arguments will delete the currently active job if it is owned by the user who invoked lprm. If the - flag is specified, lprm will remove all jobs which a user owns. If the super-user employs this flag, the spool queue will be emp- tied entirely. The owner is determined by the user's login name and host name on the machine where the lpr command was invoked. Specifying a user's name, or list of user names, will cause lprm to attempt to remove any jobs queued belonging to that user (or users). This form of invoking lprm 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 lpq(1) program, e.g. % lpq -l 1st: ken [job #013ucbarpa] (standard input) 100 bytes % lprm 13 Lprm will announce the names of any files it removes and is silent if there are no jobs in the queue which match the request list. 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. The -P option may be usd to specify the queue associated with a specific printer (otherwise the default printer, or the value of the PRINTER variable in the environment is used). 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 SEE ALSO
lpr(1), lpq(1), lpd(8) DIAGNOSTICS
``Permission denied" if the user tries to remove files other than his own. BUGS
Since there are race conditions possible in the update of the lock file, the currently active job may be incorrectly identified. 4.2 Berkeley Distribution October 22, 1996 LPRM(1)

NAME
lprm - Removes requests from the line printer spooling queue SYNOPSIS
lprm [-Pprinter] [-] [request_ID...] [user...] The lprm command removes one or more requests from a printer's spool queue. OPTIONS
Removes all requests that a user owns. If specified by a user with superuser authority, the spool queue is emptied entirely. Specifies the queue associated with a specific printer; otherwise, the default printer or the value of the PRINTER variable in the environment is used. DESCRIPTION
Because the spooling directory is protected from users, using lprm is normally the way a user can remove a request. The lprm command without any arguments deletes the currently active request if it is owned by the user who invoked lprm. The - flag removes all requests from the user issuing the command. If a user who has superuser authority uses this flag, the spool queue is emptied entirely. The owner is determined by the user's username and hostname on the machine where the lpr command was invoked. You can remove an individual request from a queue by specifying its request ID. (You can obtain the request ID by using the lpq or lpstat commands.) Specifying one or more users removes any requests queued belonging to those users. This works only for a user with superuser authority. The lprm command is silent if there are no requests in the queue that match the request list. The lprm command kills an active daemon, if necessary, before removing any spooling files. If a daemon is killed, a new one is automati- cally restarted upon completion of file removals. NOTES
Because race conditions are possible in the update of the lock file, the currently active request may be incorrectly identified. DIAGNOSTICS
The user tried to remove files that belong to another user. EXAMPLES
To remove a request from the default queue by specifying the request ID, enter: lprm 13 To remove a request from a specific queue, enter: lprm -Plp0 13 To remove from a specific queue a request from user guest, enter: lprm -Plp0 guest FILES
Printer description file. Spool directories. Daemon control files. Data files specified in cf files. Temporary copies of cf files. Lock file used to obtain the process ID of the current daemon and the request ID of the currently active request. SEE ALSO
