.TH LPQ 1 "25 February 1983" .UC 4 .ad .SH NAME lpq \- spool queue examination program .SH SYNOPSIS .B lpq [ +[ n ] ] [ \-Pprinter ] [ job # ... ] [ user ... ] .SH DESCRIPTION .PP .I lpq will examine the spooling area used by .IR lpd (8) for printing files on the line printer, and report the status of the specified jobs or all jobs associated with a user. .I lpq invoked without any arguments will report on any jobs currently in the queue. A .B \-P flag may be used to specify a particular printer, otherwise the default line printer is used (or the value of the PRINTER variable in the environment). If a .B \+ argument is supplied, .I lpq will display the spool queue until it empties. Supplying a number immediately after the .B \+ sign indicates that .I lpq should sleep \fIn\fR seconds in between scans of the queue. Any other arguments supplied will be interpreted as user names or job numbers to filter out only those jobs of interest. .PP For each job submitted (i.e. invocation of .IR lpr (1)) .I lpq reports the user's name, current rank in the queue, the names of files comprising the job, and the job identifier (a number which may be supplied to .IR lprm (1) for removing a specific job). 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 .IR lpr (1) is used as a sink in a pipeline) in which case the file is indicated as ``(standard input)". The size of a file is reported in bytes. .SH FILES .nf .ta \w'/etc/passwd 'u /etc/passwd for user names /etc/termcap for manipulating the screen for repeated display /etc/printcap to determine printer characteristics /usr/spool/* the spooling directory, as determined from printcap /usr/spool/*/cf* control files specifying jobs /usr/spool/*/lock the lock file to obtain the pid of the currently active job .fi .SH "SEE ALSO" lpr(1), lprm(1), lpd(8) .SH 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. .SH DIAGNOSTICS Unable to open various files. The lock file being malformed. Garbage files when there is no daemon active, but files in the spooling directory.
