lprm - remove jobs from the line printer spooling queue
lprm [-] [-Pprinter] [[job# ...][user ...]]
lprm will remove a job, or jobs, from a printer's spool
queue. Since the
spooling directory is protected from users, using lprm is
only method by which a user may remove a job. The owner of
a job is determined
by the user's login name and host name on the machine where the
lpr(1) command was invoked.
Options and arguments:
Specify the queue associated with a specific printer
the default printer is used).
- If a single ``-'' is given, lprm will remove all
jobs which a user
owns. If the superuser employs this flag, the
will be emptied entirely.
user Causes lprm to attempt to remove any jobs queued belonging to
that user (or users). This form of invoking lprm is
to the superuser.
job # A user may dequeue an individual job by specifying
its job number.
This number may be obtained from the lpq(1)
% lpq -l
(standard input) 100 bytes
% lprm 13
If neither arguments or options are given, lprm will delete
active job if it is owned by the user who invoked lprm.
lprm announces 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 daemon, if necessary, before
spooling files. If a daemon is killed, a new one is automatically
restarted upon completion of file removals.
If the following environment variable exists, it is utilized
PRINTER If the environment variable PRINTER exists, and a
not been specified with the -P option, the default
assumed from PRINTER.
/etc/printcap Printer characteristics file.
/var/spool/output/* Spooling directories.
/var/spool/output/*/lock Lock file used to obtain the PID
of the current
daemon and the job number of
Printed if the user tries to remove files other than
lpq(1), lpr(1), lpd(8)
The lprm command appeared in 3.0BSD.
Since there are race conditions possible in the update of
the lock file,
the currently active job may be incorrectly identified.
