title: Add action into artisan command
body: <p>Can I add extra action or run something after eg. running the command <code>php artisan down</code>?</p>
  
  <p>I want to do something else after I've ran that command.
  Can I extend upon the existing <code>down()</code> command or I will need to write a new custom artisan command and run that instead and have that call <code>down()</code> command?</p>
  
  <p>What I want to do here is push an event to third party API when the application is brought down.</p>
