In Unix, how do I cancel a batch job?

In Unix, if you scheduled a job with at or batch, you can cancel it at the Unix prompt by entering:

Replace <jobnum> with the number of the job that at or batch reported when you submitted the job. On some systems, you may use atrm instead of at -r .

If you don't remember the job number, you can get a listing of your jobs by entering:

Each job will be listed with its job number queue and the time it was originally scheduled to execute.

On some systems, the atq command is available to list all the jobs on the system. To use this command, at the Unix prompt, enter:

If your job is already running, you will need to find the process ID and kill it. On System V implementations (including all UITS central systems at Indiana University), list all running processes by entering:

Replace username with your username. The equivalent BSD command is:

Once you have the process ID, enter:

Replace <process ID> with the process ID. If it still will not terminate, try entering:

Note: Other scheduling programs, such as NQS and LoadLeveler, work differently and are not controlled by the same methods. For more information, see the appropriate man pages.
