AT jobs not running

  • 772

Ubuntu 10.04 Server

I am using at to have a bash script schedule itself to run again a particular interval after it completes: (here is the last line of that script)

echo "$0" | at tomorrow + 5minutes

The job gets scheduled, but does not run. When I run atq, I see the job is scheduled, but it is now well past the time it should have run:

9       Sat Jun  4 11:38:00 2011 = username

Time now:
$ date 

Sat Jun  4 22:55:09 EDT 2011

Nothing shows up in my CRON log about it. Is there some other log it would show up in? Is there some way I can force it to run? Google has not been very helpful, since it does not understand that at is the name of a program...

Edit: The job probably did not run because of a broken Ubuntu update: 

Jun  4 11:38:00 server01 atd[32330]: Module is unknown

https://bugs.launchpad.net/ubuntu/+source/pam/+bug/790538

Now that is fixed, what is the best way to run the job manually?

scheduled-task cron task-scheduler at

  1. Is it possible that atd is not running?

    ps -ef|grep atd

    This is a bit of a long shot because you would get a warning from the at command if the daemon were not running.
