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.

DESCRIPTION

  Because the spooling directory is protected from users, using lprm is nor-
  mally 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 automatically res-
  tarted upon completion of file removals.

FLAGS

  -   Removes all requests that a user owns.  If specified by a user with
      superuser authority, the spool queue is emptied entirely.

  -Pprinter
      Specifies the queue associated with a specific printer; otherwise, the
      default printer or the value of the PRINTER variable in the environment
      is used.

EXAMPLES

   1.  To remove a request from the default queue by specifying the request
       ID, enter:
	    lprm 13


   2.  To remove a request from a specific queue, enter:
	    lprm -Plp0 13


   3.  To remove from a specific queue a request from user guest, enter:
	    lprm -Plp0 guest


NOTES

  Because race conditions are possible in the update of the lock file, the
  currently active request may be incorrectly identified.

		The user tried to remove files that belong to another user.
