title: Regular expression to remove everything but the date?
body: <p>I have a file named </p>
  
  <pre><code>SMITH FAMILY TRUST S09 T90N R42W 30011498002 EXHIBIT USACE 06-24-2013.dwg 
  </code></pre>
  
  <p>and I'm looking for a regular expression that will remove everything except the date 06-24-2013.  </p>
  
  <p>Below is my code that matches the date itself but I'm unsure how to reverse it.</p>
  
  <pre><code>[0-9]{2}-[0-9]{2}-[0-9]{4}
  </code></pre>
