title: Linux Command Shortcut Variables
body: <p>I'm rubbish at Linux, so this is probably an easy question...</p>
  
  <p>I want the executable here:</p>
  
  <pre><code>/root/hiphop/hiphop-php/src/hphp/hphp
  </code></pre>
  
  <p>To be run when I type:</p>
  
  <pre><code>hphp
  </code></pre>
  
  <p>How do I set that?</p>
