lpq -- spool queue examination program SYNOPSIS
lpq [-al] [-P printer] [-w maxwait] [job# ...] [user ...] DESCRIPTION
lpq examines the spooling area used by lpd(8) for printing files on the line printer, and reports the status of the specified jobs or all jobs associated with a user. lpq invoked without any arguments reports on any jobs currently in the queue. Options: -P Specify a particular printer, otherwise the default line printer is used (or the value of the PRINTER variable in the environment). All other arguments supplied are interpreted as user names or job numbers to filter out only those jobs of interest. -l Information about each of the files comprising the job entry is printed. Normally, only as much information as will fit on one line is displayed. -a Report on the local queues for all printers, rather than just the specified printer. -w maxwait Specify the maximum time to wait in seconds for remote responses. The default is 300 seconds or 5 minutes. For each job submitted (i.e. invocation of lpr(1)) lpq reports the user's name, current rank in the queue, the names of files comprising the job, the job identifier (a number which may be supplied to lprm(1) for removing a specific job), and the total size in bytes. Job ordering is dependent on the algorithm used to scan the spooling directory and is supposed to be FIFO (First in First Out). File names comprising a job may be unavailable (when lpr(1) is used as a sink in a pipeline) in which case the file is indicated as ``(standard input)''. If lpq warns that there is no daemon present (i.e. due to some malfunction), the lpc(8) command can be used to restart the printer daemon. ENVIRONMENT
If the following environment variable exists, it is used by lpq: PRINTER Specifies an alternative default printer. FILES
/etc/printcap To determine printer characteristics. /var/spool/output/* The spooling directory, as determined from printcap. /var/spool/output/*/cf* Control files specifying jobs. /var/spool/output/*/lock The lock file to obtain the currently active job. DIAGNOSTICS
Unable to open various files. The lock file being malformed. Garbage files when there is no daemon active, but files in the spooling direc- tory. SEE ALSO
lpr(1), lprm(1), lpc(8), lpd(8) HISTORY
lpq appeared in 3BSD. BUGS
Due to the dynamic nature of the information in the spooling directory lpq may report unreliably. Output formatting is sensitive to the line length of the terminal; this can results in widely spaced columns. BSD

       lprm - remove jobs from line printer queue

       lprm [-Pprinter] [-] [job #...] [user...]

       The  command removes a job, or jobs, from a printer's spool queue.  Since the spooling directory is protected from users, using is normally
       the only method by which a user may remove a job.

       The command without any arguments deletes the currently active job if it is owned by the user who invoked

       If the - flag is specified, removes all jobs which a user owns.	If the super-user employs this flag, the spool queue is emptied  entirely.
       The owner is determined by the user's login name and host name on the machine where the command was invoked.

       Specifying  a user's name, or list of user names, causes to attempt to remove any jobs queued belonging to that user (or users).  This form
       of invoking 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 program.  For example,
       % lpq -l

       1st: ken  [job #013ucbarpa]
	    (standard input)	100 bytes
       % lprm 13

       The command announces the names of any files it removes and is silent if there are no jobs in the queue which match the request list.

       The command kills off an active daemon, if necessary, before removing any spooling files.  If a daemon is killed, a new	one  is  automati-
       cally restarted upon completion of file removals.

       -		   Removes all jobs owned by you only.

       -P printer	   Removes jobs from specified printer.  It may be used 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).

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

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

       /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
