lprm(1) General Commands Manual 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 su- peruser 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 re- quest 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 re- quest 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 automatically 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.
