LPRM(1)

NAME
lprm - remove jobs from the line printer spooling queue

SYNOPSIS
lprm [ -a ] [ -A ] [ -Ddebugopt ] [ -Pprinter ] [ -V ] [ -Uuser ]
[ jobid... ] [ all ]

DESCRIPTION

Lprm will send a request to the LPD server to remove jobs from a spool queue. (See clean(1) for an lp(1) compatible interface.) 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 specifiers 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 or the all spool queue is specified, lprm will search all available spool queues.

The all wildcard jobid is used to match all jobs in a spool queue; however unless the user has control permissions for the spool queue only the user's 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 identifier, 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 -Pp1 25

Remove job 25 and 30 in spool queue p1:

    lprm -Pp1 25 30

Remove all of user john's jobs in spool queue p1:

    lprm -Pp1 john

Remove all jobs in spool queue p1:

    lprm -Pp1 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 -Pp1 'nobody@system*'

OPTIONS

-A  Use authentication specified by the value of the AUTH environment variable.

-a  Remove files from all spool queues available to the user.

-Pprinter
    Specifies printer queue. By default, the destination printer is taken from the command line dest value, then the environment variables PRINTER, LPDEST, NPRINTER, NGPRINTER, then first entry in the printcap information, and and finally the default_printer entry from the configuration file, and then the compile time default.

-Uuser
    Explicitly provide a userid for doing the removal to the LPD server. This can be done only by ROOT or userids listed in the allow_user_setting configuration or printcap option. This facility is provided to allow printing front end systems such as SAMBA to submit job removal requests on behalf of users.

-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.

ENVIRONMENT

By default, the destination printer is taken from the command line dest value, then the environment variables PRINTER, LPDEST, NPRINTER, NGPRINTER, then first entry in the printcap information, and and finally the default_printer entry from the configuration file, and then the compile time default.

EXIT STATUS

The following exit values are returned:

zero (0)
    Successful completion.

non-zero (!=0)
    An error occurred.

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
${HOME}/.printcap	user printer description file
/etc/printcap	printer description file
/etc/lpd.perms	permissions
/var/run/lpd	lock file for queue control
/var/spool/lpd		spool directories
/var/spool/lpd/QUEUE/control	queue control
/var/spool/lpd/QUEUE/log	trace or debug log file
/var/spool/lpd/QUEUE/acct	accounting file
/var/spool/lpd/QUEUE/status	status 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.
