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 nor- mally 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 the super-user employs this flag, the spool queue will be emp- tied entirely. The owner is determined by the user's login name and host name on the machine where the lpr command was invoked. 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 the super-user. 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 daemon, if necessary, before removing any spooling files. If a daemon 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 daemon and the job number of the currently active job SEE ALSO
lpr(1), lpq(1), lpd(8) DIAGNOSTICS
``Permission denied" if the user tries to remove files other than his own. BUGS
Since there are race conditions possible in the update of the lock file, the currently active job may be incorrectly identified. 4.2 Berkeley Distribution October 22, 1996 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 vari- ables 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 SEE ALSO

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
