LPRM(1) UNIX Programmer's Manual LPRM(1) NAME lprm - remove jobs from the line printer spooling queue SYNOPSIS lprm [ -P_p_r_i_n_t_e_r ] [ - ] [ job # ... ] [ user ... ] DESCRIPTION _L_p_r_m will remove a job, or jobs, from a printer's spool queue. Since the spooling directory is protected from users, using _l_p_r_m is normally the only method by which a user may remove a job. _L_p_r_m without any arguments will delete the currently active job if it is owned by the user who invoked _l_p_r_m. If the - flag is specified, _l_p_r_m will remove all jobs which a user owns. If the super-user employs this flag, the spool queue will be emptied entirely. The owner is determined by the user's login name and host name on the machine where the _l_p_r command was invoked. Specifying a user's name, or list of user names, will cause _l_p_r_m to attempt to remove any jobs queued belonging to that user (or users). This form of invoking _l_p_r_m 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 _l_p_q(1) pro- gram, e.g. % lpq -l 1st: ken [job #013ucbarpa] (standard input) 100 bytes % lprm 13 _L_p_r_m 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. _L_p_r_m 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 remo- vals. 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).
