How to start/stop/restart delayed_jobs from the command line

Delayed Jobs is a background processing tool written in ruby. When you use it inside a Ruby on Rails application, usually you start it with:

rake jobs:work

If you need to start delayed jobs from a Capistrano task or from a monitoring framework like God, you should use the following commands.
To start:

script/delayed_job start

To stop:

script/delayed_job stop

To restart:

script/delayed_job restart

Hope this helps.
