Print status with qstat

qstat [-alsv] [-q queue]

Description

See also the qstat man page.

Use qstat to print out the status of mdqs queues.

What is it used for?

Qstat is useful for figuring out whether a user's job is in the queue. It's also useful for discovering why/if jobs are taking a long time to print (e.g. the queue may be very long, or a very large job might be printing out).

qstat may give the first indication that something is wrong with a printer (e.g. a queue might have an abnormally long waiting list, which prompts you to use hpstat to check the status of the printer).

Option descriptions/example outputs

default behavior

If you call qstat with no options listed it will give the status for the queues on the spooler for the printer that is listed in the environment variable $PRINTER. Qstat looks at $PRINTER to determine which spooler to connect to. If $PRINTER is not set it tries to connect to the local host.

Job descriptions

Default listing

the short job listing

hornbake        mdqs.14227

lists the

queue the job is in, and gives the process id (pid) of the job. It also lists whether the job is being held or delayed.

long listing

the long job listing

hornbake  mdqs.14241 mac01ugli@mac01ug wam.umd.edu 8   64  89k Jan  5 13:55

lists the queue, pid, user, priority number (usually 64), size, and a timestamp. It also lists whether the job is held or delayed.

The user field changes according to platform and lab configuration. On unix machines the user will be the login id of the user and the machine name that the user submitted the job from. On most Macs and PC's the user will be the lab number of the machine. On PC's with an old lab configuration, the user field is not used.
