X.SH NAME lpq \- spool queue examination program X.SH SYNOPSIS X.B lpq X[\-Pprinter ]*[\-a][\-l][+[n]][\-D[n]][\-X][ job # ... ][ user ... ] X.SH DESCRIPTION X.I lpq examines the spooling area used by X.IR lpd (8) for printing files on the line printer, and reports the status of the specified jobs or all jobs associated with a user. X.I lpq invoked without any arguments reports on the printer given by the default printer X(see X.B \-P option). XFor each job submitted (i.e. invocation of X.IR lpr (1)) X.I 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 X.IR 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 XFIFO (First in First Out), in order of priority level. XFile names comprising a job may be unavailable X(when X.IR lpr (1) is used as a sink in a pipeline) in which case the file is indicated as ``(stdin)''. The following options are available. X.IP "\fB\-P \fIprinter\fR" Specifies a particular printer, otherwise the default line printer is used (or the value of the PRINTER variable in the environment). If PRINTER is not defined, then the first entry in the X.IR /etc/printcap (5) file is reported. Multiple printers can be displayed by specifying more than one X\-P option. X.IP "\fB\-a\fR" All printers listed in X.IR /etc/printcap (5) file are reported. X.IP "\fB\-l\fR" An a\fBl\fRternate display format is used, which simply reports the user, jobnumber, and originating host. X.IP "[\fB+\fR[\fIn\fR]]" XForces X.I lpq to periodically display the spool queues. Supplying a number immediately after the X.B \+ sign indicates that X.I lpq should sleep \fIn\fR seconds in between scans of the queue. X.IP "\fB\-D\fR[\fIn\fR]" XEnables display of debugging information. The X.B \-D\fIn\fR X\fRselects level X.I n X(n is a single digit). X.IP "\fB\-X" Use an Xperimental version of LPD if the software has been compiled with the appropriate support; ignored otherwise. X.IP "[ job # ... ][ user ... ]" The options are followed by a list of user names or job numbers which are used to select jobs of interest. X.PP The X.I lpq will report the status of the spool queue (enabled for spooling, disabled for unspooling), and the abscense of a server if unspooling is enabled. The X.IR lpc (1) command X.I "lpc restart <printer>" may be used to start the server if this is the case.

X.SH NAME lprm \- remove jobs from the line printer spooling queue X.SH SYNOPSIS X.B lprm X[ X.BI \-P printer X] [ X.B \- X] [ X.BI \-D n X] [ X.B \-X X] [ job # ... X] [ user ... X] X.SH DESCRIPTION X.I Lprm will remove jobs from a spool queue. Since the spooling directory and files in it are owned by X.I daemon, using X.I lprm is normally the only method by which a user may remove a job. X.PP The use must specify the job to be removed by providing a job number or user name. Ordinary users may remove jobs which are submitted by themselves; users with X.I Control permissions in the X.I printer_perms file may remove other users jobs. Root can remove jobs on the local host and jobs submitted from the local host. X.PP If the X.B \- flag is specified, X.I lprm will remove all jobs which a user owns. If a user with X.I control permissions uses this flag, the spool queue will be emptied entirely. The submitter of a job is determined by the information returned by X.IR getpwent (3) for the real userid of the process, and the host name by the information returned by X.IR gethostent (3). X.PP Specifying a user's name or list of user names will cause X.I lprm to attempt to remove any jobs queued belonging to that user X(or users). This form of invoking X.I lprm is useful only to the super-user or users with X.I control permissions. X.PP A user may dequeue an individual job by specifying its job number. This number may be obtained by using X.IR lpq (1). X.I 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. X.PP If necessary, X.I lprm will kill off an active spool queue server which is processing a job to be removed. After jobs have been removed, the server will be restarted. X.IP \fB\-P\fP\ printer The X.B \-P option specifies the spooling queue. If it is not provided, the default printer is the the value of the PRINTER environment variable and then the first printer in the X.I printcap database. X.IP \fB\-D\fR[\fIn\fR] The X.B \-D\fIn\fR X\fRselects debugging level X.I n X(n is a single digit). This may be used to produce a trace of the actions of X.IR lprm . X.IP \fB\-X\fR The \fB\-X option uses an Xperimental version of lpd if the software has been compiled with the appropriate support; ignored otherwise.
