lprm(1)                        DG/UX R4.11MU05                       lprm(1)


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
       normally 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 a user with appropriate privilege 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 lpr command
       was invoked.  For systems supporting the DG/UX Capability Option,
       appropriate privilege is defined as having one or more specific
       capabilities enabled in the effective capability set of the user.
       See capdefaults(5) for the default capabilities for this command.

       On systems without the DG/UX Capability Option, appropriate privilege
       means that your process has an effective UID of root.  See the
       appropriateprivilege(5) man page for more information.

       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 a user with appropriate
       privilege.

       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 server (daemon), if necessary, before
       removing any spooling files.  If a server 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
                          spooler and the job number of the currently active
                          job

DIAGNOSTICS
       "Permission denied" if the user tries to remove files other than his
       own.

SEE ALSO
       lpd(1M), lpq(1), lpr(1).  appropriateprivilege(5).
       capdefaults(5).

NOTES
       Since there are race conditions possible in the update of the lock
       file, the currently active job may be incorrectly identified.
