|
|
.Nm
|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility examines the spooling area used by
|
|
.Xr 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
|
|
.Nm
|
|
utility invoked
|
|
without any arguments reports on any jobs currently in the queue.
|
|
.Pp
|
|
Options:
|
|
.Bl -tag -width indent
|
|
.It Fl P
|
|
Specify a particular printer, otherwise the default
|
|
line printer is used (or the value of the
|
|
.Ev 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.
|
|
.It Fl 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.
|
|
.It Fl a
|
|
Report on the local queues for all printers,
|
|
rather than just the specified printer.
|
|
.El
|
|
.Pp
|
|
For each job submitted (i.e., invocation of
|
|
.Xr lpr 1 )
|
|
.Nm
|
|
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
|
|
.Xr 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
|
|
.Tn FIFO
|
|
(First in First Out).
|
|
File names comprising a job may be unavailable
|
|
(when
|
|
.Xr lpr 1
|
|
is used as a sink in a pipeline) in which case the file
|
|
is indicated as ``(standard input)''.
|
|
.Pp
|
|
If
|
|
.Nm
|
|
warns that there is no daemon present (i.e., due to some malfunction),
|
|
the
|
|
.Xr lpc 8
|
|
command can be used to restart the printer daemon.
|
|
.Sh ENVIRONMENT
|
|
If the following environment variable exists, it is used by
|
|
.Nm :
|
|
.Bl -tag -width PRINTER
|
|
.It Ev PRINTER
|
|
Specifies an alternate default printer.
|
|
.El
|
|
.Sh FILES
|
|
.Bl -tag -width "/var/spool/*/lock" -compact
|
|
.It Pa /etc/printcap
|
|
To determine printer characteristics.
|
|
.It Pa /var/spool/*
|
|
The spooling directory, as determined from printcap.
|
|
.It Pa /var/spool/*/cf*
|
|
Control files specifying jobs.
|
|
.It Pa /var/spool/*/lock
|
|
The lock file to obtain the currently active job.
|
|
.El
|
|
.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.

.Sh HISTORY
|
|
A
|
|
.Nm
|
|
utility appeared in
|
|
.Bx 3 .
|
|
.Sh BUGS
|
|
Due to the dynamic nature of the information in the spooling directory
|
|
.Nm
|
|
may report unreliably.
|
|
Output formatting is sensitive to the line length of the terminal;
|
|
this can results in widely spaced columns.
