NAME
lprm - remove jobs from the line printer spooling queue
SYNOPSIS
lprm [ -Pprinter ] [ -a ] [ -V ] [ -Ddebugopt ] [ jobid *
] [ all ]
DESCRIPTION
Lprm will send a request to the LPD server to remove jobs
from a spool queue. Lprm is normally the only method by
which a user may remove a job. The jobs to be removed are
specified by the job number or user name; with no speci-
fiers the first removable in a queue will be selected for
removal. Usually users may only remove jobs submitted by
themselves from the host which originated the original lpr
request.
The spool queue is searched first for jobs that the user
has permissions to remove, then for jobs that match any of
the specified set of tags. If no tags are specified, only
the first job in the queue that the user has permissions
to remove will be removed.
If the -a flag is specified, lprm will search all avail-
able spool queues for the specified jobs and remove them.
The all wildcard is used to match all jobs in a spool
queue; however unless the user has control permissions
for the spool queue only his jobs will be removed. See
the lpd(1) man page for details about control permissions.
A jobid can be a job number, a user name, a job identi-
fier, or a pattern for a glob based wild card match. This
match is applied to the job identifier information.
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. If the job being removed is active, the
LPD server will stop printing the job and then restart
printing operations.
EXAMPLES
Remove the last job I submitted if it is in the queue:
lprm
Remove job 25 in spool queue p1:
lprm -Pt1 25
Remove job 25 and 30 in spool queue p1:
lprm -Pt1 25 30
Remove all of user john's jobs in spool queue p1:
lprm -Pt1 john
Remove all jobs in spool queue p1:
lprm -Pt1 all
Remove all jobs in all spool queues:
lprm -a all
Remove the jobs with identifier nobody@system in spool
queue p1.
Note that the quotes around the pattern are needed
to suppress shell glob expansion.
lprm -Pt1 'nobody@system*'
OPTIONS
-a Remove files from all spool queues available to the
user.
-Pprinter
Specifies printer queue. If it is not provided, the
default printer is the value of the PRINTER environ-
ment variable, or the first printer in the printcap
database if it is not defined.
-Ddebugopts
Debugging is controlled using the -D option. This
accepts a comma-separated list of debugging settings.
These settings take one of two forms: facility=value
, or value to set an overall default value.
-V The -V option prints the version information for the
program and verbose information about activities.
WARNINGS
Users with CONTROL (i.e.- administrative) permissions on
spool queues can remove any or all jobs. The all wildcard
defaults to all user jobs, not just those submitted by the
user. This allows administrators to purge a spool queue
easily.
FILES
The files used by LPRng are set by values in the printer
configuration file. The following are a commonly used set
of default values.
/etc/lpd.conf LPRng configuration file
/etc/printcap printer description file
/etc/lpd.perms printer permissions
/var/spool/printer* spool directories
/var/spool/printer*/printer lock file for queue control
/var/spool/printer*/control.printer queue control
/var/spool/printer*/active.printer active job
/var/spool/printer*/log.printer log file

DIAGNOSTICS
Most of the diagnostics are self explanatory.
If you are puzzled over the exact cause of failure,
set the debugging level on (-D5) and run again.
The debugging information will
help you to pinpoint the exact cause of failure.
HISTORY
LPRng is a enhanced printer spooler system, with function-
ality similar to the Berkeley LPR software, and is derived
from the PLP (Public Line Printer) software, version 4.0.
LPRng has many advanced features, which are described in
LPRng - An Enhanced Line Printer Spooler by Patrick Pow-
ell, San Diego State University (papowell@sdsu.edu), et
al. It is available from dickory.sdsu.edu:/pub/LPRng.
The LPRng software is based on PLP4.0, supported and
extended by Justin Mason (jmason@iona.ie), which is avail-
able from ftp://ftp.iona.ie/pub/PLP4.0. Justin greatly
aided in the design and development of many of the soft-
ware features, as well as contributing a large number of
bug fixes, design reviews, and other suggestions.
