lprm - Removes requests from the line printer spooling queue
lprm [-Pprinter] [-] [request_ID...] [user...]
The lprm command removes one or more requests from a printer's spool queue.
- 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
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.
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.
