The cron job for updatedb didn't run because the system was powered off at the time. I'd like to tell cron to run that job now, as if now were the schedule time. Is there a way to do that?
For this job I don't want to run it in the foreground because I don't want to keep it open, and I don't want to run it in a screen because I don't want to have to clean it up later. On many other occasions it would have been useful to do the same thing to test that a job would execute correctly in the environment provided by cron.
