Managing Print Queues

Managing Print Queues

The pqlist command lists all of the print queues available to you on the specified server. If you do not specify a fileserver on the command line using the -S option, or a login name and password, these will be taken from the default entry in your ~/.nwclient file:

# pqlist -S vbrew_f1 -U guest -n
Server: ALES_F1
Print queue name                                    Queue ID 
------------------------------------------------------------
TEST                                                AA02009E
Q2                                                  EF0200D9
NPI223761_P1                                        DA03007C
Q1                                                  F1060004
I-DATA                                              0D0A003B
NPI223761_P3                                        D80A0031

Our example shows a list of the print queues available to the guest user on the ALES_F1 fileserver.[88]

To view the print jobs on a print queue, use the pqstat command. It takes the print queue name as an argument and lists all of the jobs in that queue. You may optionally supply another argument indicating how many of the jobs in the queue you'd like to list. The following sample output has been compressed a bit to fit the width of this book's page:

$ pqstat -S ALES_F1 NPI223761_P1
Server: ALES_F1     Queue: NPI223761_P1          Queue ID: 6A0E000C
   Seq  Name      Description                    Status   Form  Job ID 
------------------------------------------------------------------------
     1  TOTRAN    LyX document - proposal.lyx    Active      0  02660001

We can see just one print job in the queue, owned by user TOTRAN. The rest of the options include a description of the job, its status, and its job identifier.

The pqrm command is used to remove print jobs from a specified print queue. To remove the job in the queue we've just obtained the status of, we'd use:

$ pqrm -S ALES_F1 NPI223761_P1 02660001

The command is pretty straightforward but is clumsy to use in a hurry. It would be a worthwhile project to write a basic script to simplify this operation.
