LPQ(1) BSD General Commands Manual LPQ(1) NAME lpq -- spool queue examination program SYNOPSIS lpq [-a] [-l] [-Pprinter] [job # ...] [user ...] DESCRIPTION The lpq utility 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. The lpq utility 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 environ- ment). 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. 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 remov- ing a specific job), and the total size in bytes. Job ordering is depen- dent 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 un- available (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 malfunc- tion), 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 alternate default printer. FILES /etc/printcap To determine printer characteristics. /var/spool/* The spooling directory, as determined from printcap. /var/spool/*/cf* Control files specifying jobs. /var/spool/*/lock The lock file to obtain the currently active job. SEE ALSO lpr(1), lprm(1), lpc(8), lpd(8) HISTORY A lpq utility 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. 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. BSD April 28, 1995 BSD
