.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Ar command Op Ar argument ...
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is used by the system administrator to control the
|
|
operation of the line printer system.
|
|
For each line printer configured in
|
|
.Pa /etc/printcap ,
|
|
.Nm
|
|
may be used to:
|
|
.Bl -bullet -offset indent
|
|
.It
|
|
disable or enable a printer,
|
|
.It
|
|
disable or enable a printer's spooling queue,
|
|
.It
|
|
rearrange the order of jobs in a spooling queue,
|
|
.It
|
|
find the status of printers, and their associated
|
|
spooling queues and printer daemons,
|
|
.It
|
|
change the status message for printer queues (the status message
|
|
may be seen by users as part of the output of the
|
|
.Xr lpq 1
|
|
utility).
|
|
.El
|
|
.Pp
|
|
Without any arguments,
|
|
.Nm
|
|
will prompt for commands from the standard input.
|
|
If arguments are supplied,
|
|
.Nm
|
|
interprets the first argument as a command and the remaining
|
|
arguments as parameters to the command.
|
|
The standard input
|
|
may be redirected causing
|
|
.Nm
|
|
to read commands from file.
|
|
Commands may be abbreviated;
|
|
the following is the list of recognized commands.
|
|
.Pp
|
|
.Bl -tag -width indent -compact
|
|
.It Ic \&? Op Ar command ...
|
|
.It Ic help Op Ar command ...
|
|
Print a short description of each command specified in the argument list,
|
|
or, if no argument is given, a list of the recognized commands.
|
|
.Pp
|
|
.It Ic abort Brq Cm all | Ar printer
|
|
Terminate an active spooling daemon on the local host immediately and
|
|
then disable printing (preventing new daemons from being started by
|
|
.Xr lpr 1 )
|
|
for the specified printers.
|
|
.Pp
|
|
.It Ic bottomq Ar printer Op Ar jobspec ...
|
|
Take the specified jobs in the order specified and move them to the
|
|
bottom of the printer queue.
|
|
Each
|
|
.Ar jobspec
|
|
can match multiple print jobs.
|
|
The full description of a
|
|
.Ar jobspec
|
|
is given below.
|
|
.Pp
|
|
.It Ic clean Brq Cm all | Ar printer
|
|
Remove any temporary files, data files, and control files that cannot
|
|
be printed (i.e., do not form a complete printer job)
|
|
from the specified printer queue(s) on the local machine.
|
|
This command will also look for
|
|
.Pa core
|
|
files in spool directory
|
|
for each printer queue, and list any that are found.
|
|
It will not remove any
|
|
.Pa core
|
|
files.
|
|
See also the
|
|
.Ic tclean
|
|
command.
|
|
.Pp
|
|
.It Ic disable Brq Cm all | Ar printer
|
|
Turn the specified printer queues off.
|
|
This prevents new
|
|
printer jobs from being entered into the queue by
|
|
.Xr lpr 1 .
|
|
.Pp
|
|
.It Ic down Bro Cm all | Ar printer ... Brc Cm -msg Ar message ...
|
|
.It Ic down Bro Cm all | Ar printer Brc Ar message ...
|
|
Turn the specified printer queue off, disable printing and put
|
|
.Ar message
|
|
in the printer status file.
|
|
When specifying more than one printer queue, the
|
|
.Ic -msg
|
|
argument is required to separate the list of printers from the text
|
|
that will be the new status message.
|
|
The message does not need to be quoted, the
|
|
remaining arguments are treated like
|
|
.Xr echo 1 .
|
|
This is normally used to take a printer down, and let other users
|
|
find out why it is down (the
|
|
.Xr lpq 1
|
|
utility will indicate that the printer is down and will print the
|
|
status message).
|
|
.Pp
|
|
.It Ic enable Brq Cm all | Ar printer
|
|
Enable spooling on the local queue for the listed printers.
|
|
This will allow
|
|
.Xr lpr 1
|
|
to put new jobs in the spool queue.
|
|
.Pp
|
|
.It Ic exit
|
|
.It Ic quit
|
|
Exit from
|
|
.Nm .
|
|
.Pp
|
|
.It Ic restart Brq Cm all | Ar printer
|
|
Attempt to start a new printer daemon.
|
|
This is useful when some abnormal condition causes the daemon to
|
|
die unexpectedly, leaving jobs in the queue.
|
|
.Xr lpq 1
|
|
will report that there is no daemon present when this condition occurs.
|
|
If the user is the super-user,
|
|
try to abort the current daemon first (i.e., kill and restart a stuck daemon).
|
|
.Pp
|
|
.It Ic setstatus Bro Cm all | Ar printer Brc Cm -msg Ar message ...
|
|
Set the status message for the specified printers.
|
|
The
|
|
.Ic -msg
|
|
argument is required to separate the list of printers from the text
|
|
that will be the new status message.
|
|
This is normally used to change the status message when the printer
|
|
queue is no longer active after printing has been disabled, and you
|
|
want to change what users will see in the output of the
|
|
.Xr lpq 1
|
|
utility.
|
|
.Pp
|
|
.It Ic start Brq Cm all | Ar printer
|
|
Enable printing and start a spooling daemon for the listed printers.
|
|
.Pp
|
|
.It Ic status Brq Cm all | Ar printer
|
|
Display the status of daemons and queues on the local machine.
|
|
.Pp
|
|
.It Ic stop Brq Cm all | Ar printer
|
|
Stop a spooling daemon after the current job completes and disable
|
|
printing.
|
|
.Pp
|
|
.It Ic tclean Brq Cm all | Ar printer
|
|
This will do a test-run of the
|
|
.Ic clean
|
|
command.
|
|
All the same checking is done, but the command will only print out
|
|
messages saying what a similar
|
|
.Ic clean
|
|
command would do if the user typed it in.
|
|
It will not remove any files.
|
|
Note that the
|
|
.Ic clean
|
|
command is a privileged command, while the
|
|
.Ic tclean
|
|
command is not restricted.
|
|
.Pp
|
|
.It Ic topq Ar printer Op Ar jobspec ...
|
|
Take the specified jobs in the order specified and move them to the
|
|
top of the printer queue.
|
|
Each
|
|
.Ar jobspec
|
|
can match multiple print jobs.
|
|
The full description of a
|
|
.Ar jobspec
|
|
is given below.
|
|
.Pp
|
|
.It Ic up Brq Cm all | Ar printer
|
|
Enable everything and start a new printer daemon.
|
|
Undoes the effects of
|
|
.Ic down .
|
|
.El
|
|
.Pp
|
|
Commands such as
|
|
.Ic topq
|
|
and
|
|
.Ic bottomq
|
|
can take one or more
|
|
.Ar jobspec
|
|
to specify which jobs the command should operate on.
|
|
A
|
|
.Ar jobspec
|
|
can be:
|
|
.Bl -bullet
|
|
.It
|
|
a single job number, which will match all jobs in the printer's queue
|
|
which have the same job number.
|
|
Eg:
|
|
.Ar 17 ,
|
|
.It
|
|
a range of job numbers, which will match all jobs with a number between
|
|
the starting and ending job numbers, inclusive.
|
|
Eg:
|
|
.Ar 21-32 ,
|
|
.It
|
|
a specific userid, which will match all jobs which were sent by that
|
|
user.
|
|
Eg:
|
|
.Ar jones ,
|
|
.It
|
|
a host name, when prefixed by an `@', which will match all jobs in
|
|
the queue which were sent from the given host.
|
|
Eg:
|
|
.Ar @freebsd.org ,
|
|
.It
|
|
a job range and a userid, separated by a `:', which will match all jobs
|
|
which both match the job range and were sent by the specified user.
|
|
Eg:
|
|
.Ar jones:17
|
|
or
|
|
.Ar 21-32:jones ,
|
|
.It
|
|
a job range and/or a userid, followed by a host name, which will match
|
|
all jobs which match all the specified criteria.
|
|
Eg:
|
|
.Ar jones@freebsd.org
|
|
or
|
|
.Ar 21-32@freebsd.org
|
|
or
|
|
.Ar jones:17@freebsd.org .
|
|
.El
|
|
.Pp
|
|
The values for userid and host name can also include pattern-matching
|
|
characters, similar to the pattern matching done for filenames in
|
|
most command shells.
|
|
Note that if you enter a
|
|
.Ic topq
|
|
or
|
|
.Ic bottomq
|
|
command as parameters on the initial
|
|
.Nm
|
|
command, then the shell will expand any pattern-matching characters
|
|
that it can (based on what files in finds in the current directory)
|
|
before
|
|
.Nm
|
|
processes the command.
|
|
In that case, any parameters which include pattern-matching characters
|
|
should be enclosed in quotes, so that the shell will not try to
|
|
expand them.
