title: Running bash on heroku won't work
body: <p>I am trying to run bash on heroku to test it out and it is failing</p>
  
  <blockquote>
  <pre><code> $ heroku run bash
   ▸    Error: No app specified
   ▸    Usage: heroku run --app APP
   ▸    We don't know which app to run this on.
   ▸    Run this command from inside an app folder or specify which app to use with --app APP

   ▸    Example: heroku run bash
  </code></pre>
