title: Exiting the Rails console after an error
body: <p>I have been use the rails console for testing and learning purposes and when I encounter an error I cannot exit anymore using the "Control + C" command. Is there another command to exit? 
  This is what the console looks like when I try to do this:</p>
  
  <pre><code>ruby-1.9.2-p180 :026 &gt; user.find_by_name("Test")
  NoMethodError: undefined method `find_by_name' for #&lt;User:0x00000100f991a0&gt;
