Without any arguments, lpc will prompt for commands from the standard input. If arguments are supplied, lpc interprets the first argument as a command and the remaining arguments as parameters to the command. The standard input may be redirected causing lpc to read commands from file. Commands may be abbreviated; the following is the list of recognized commands.
amp;? [command ...]
help [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.
| |
abort { all | printer} | |
Terminate an active spooling daemon on the local host immediately and
then disable printing (preventing new daemons from being started by
lpr(1))
for the specified printers.
| |
bottomq printer [jobspec ...] | |
Take the specified jobs in the order specified and move them to the
bottom of the printer queue.
Each
jobspec
can match multiple print jobs.
The full description of a
jobspec
is given below.
| |
clean { all | 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
core
files in spool directory
for each printer queue, and list any that are found.
It will not remove any
core
files.
See also the
tclean
command.
| |
disable { all | printer} | |
Turn the specified printer queues off.
This prevents new
printer jobs from being entered into the queue by
lpr(1).
| |
down { all | printer ... } -msg message ...
down { all | printer }message ... | |
Turn the specified printer queue off, disable printing and put
message
in the printer status file.
When specifying more than one printer queue, the
-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
echo(1).
This is normally used to take a printer down, and let other users
find out why it is down (the
lpq(1)
utility will indicate that the printer is down and will print the
status message).
| |
enable { all | printer} | |
Enable spooling on the local queue for the listed printers.
This will allow
lpr(1)
to put new jobs in the spool queue.
| |
exit
quit | |
Exit from
lpc.
| |
restart { all | 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.
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).
| |
setstatus { all | printer } -msg message ... | |
Set the status message for the specified printers.
The
-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
lpq(1)
utility.
| |
start { all | printer} | |
Enable printing and start a spooling daemon for the listed printers.
| |
status { all | printer} | |
Display the status of daemons and queues on the local machine.
| |
stop { all | printer} | |
Stop a spooling daemon after the current job completes and disable
printing.
| |
tclean { all | printer} | |
This will do a test-run of the
clean
command.
All the same checking is done, but the command will only print out
messages saying what a similar
clean
command would do if the user typed it in.
It will not remove any files.
Note that the
clean
command is a privileged command, while the
tclean
command is not restricted.
| |
topq printer [jobspec ...] | |
Take the specified jobs in the order specified and move them to the
top of the printer queue.
Each
jobspec
can match multiple print jobs.
The full description of a
jobspec
is given below.
| |
up { all | printer} | |
Enable everything and start a new printer daemon. Undoes the effects of down. | |
Commands such as topq and bottomq can take one or more jobspec to specify which jobs the command should operate on. A jobspec can be:
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 topq or bottomq command as parameters on the initial lpc command, then the shell will expand any pattern-matching characters that it can (based on what files in finds in the current directory) before lpc 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.
/etc/printcap | printer description file |
/var/spool/* | spool directories |
/var/spool/*/lock | lock file for queue control |
?Ambiguous command | abbreviation matches more than one command |
?Invalid command | no match was found |
?Privileged command | you must be a member of group "operator" or root to execute this command |
