title: Open most recent file in tcsh
body: <p>so I'm trying to create an alias that will open the most recent file in a directpry with an application at our studio.</p>
  
  <p>I get the most recent file with:</p>
  
  <pre><code>ls -t .ext | head -1
  </code></pre>
  
  <p>That works fine when I just run that line, but if I try either:</p>
  
  <pre><code>echo "ls -t .ext | head -1"
  app "ls -t .ext | head -1"
  </code></pre>
  
  <p>I get this returned instead of the file opening:</p>
  
  <pre><code>ls -t &lt;all the files in the directory&gt; | head -1
  </code></pre>
  
  <p>Any ideas? Much appreciated.</p>
