Top Forums UNIX for Dummies Questions & Answers Lock File Post 70913 by canman on Thursday 5th of May 2005 09:12:07 AM

A third party party application is locking a printer when certain print options are selected, thereby creating a lck file. This application has occasionally crashed, leaving this lck file present. Therefore the lock on this printer is still present and no one else from this application can print to this printer. However, the only way we have at present is to remove the lock, kill the printers, and then restart them.

As these lock files are always called lck followed by something like 8c001.
Is there anyway of linking this 8c001(device name?) to the process id of this device allowing us to write a script to do this.

Thanks

enable

enable(1)                                                          User Commands                                                         enable(1)

NAME

       enable, disable - enable/disable LP printers

SYNOPSIS

       /usr/bin/enable printer...

       /usr/bin/disable [-c | -W]  [ -r [reason]] printer...

DESCRIPTION

       The  enable  command  activates  printers,  enabling  them to print requests submitted by the lp command. enable must be run on the printer
       server.

       The disable command deactivates printers, disabling them from printing requests submitted by the lp command. By default, any requests  that
       are  currently  printing  on printer will be reprinted in their entirety either on printer or another member of the same class of printers.
       The disable command must be run on the print server.

       Use lpstat -p to check the status of printers.

       enable and disable only effect queueing on the print server's spooling system. Executing these commands from a client system will  have  no
       effect on the server.

OPTIONS

       The following options are supported for use with disable:

       -c              Cancels  any requests that are currently printing on printer. This option cannot be used with the -W option. If the printer
                       is remote, the -c option will be silently ignored.

       -W              Waits until the request currently being printed is finished before disabling printer. This option cannot be used  with  the
                       -c option. If the printer is remote, the -W option will be silently ignored.

       -r [reason]     Assigns  a  reason  for  the  disabling  of  the  printer(s). This reason applies to all printers specified. This reason is
                       reported by lpstat -p. Enclose reason in quotes if it contains blanks. The default  reason  is  "unknown  reason"  for  the
                       existing printer, and "new printer" for a printer added to the system but not yet enabled.

OPERANDS

       The following operand is supported for both enable and disable:

       printer         The  name of the printer to be enabled or disabled. Specify printer using atomic name. See printers.conf(4) for information
                       regarding the naming conventions for atomic names.

EXIT STATUS

       The following exit values are returned:

       0               Successful completion.

       non-zero        An error occurred.

FILES

       /var/spool/lp/*         LP print queue.
