title: command to grep for multiple files?
body: <p>without having to write a shell script, I'm wondering if there's a way to list files based on a match to more than one criteria?</p>
  
  <p>I know I can do: </p>
  
  <pre><code>ls ./files/ | grep samp
  </code></pre>
  
  <p>to get a list of all files that contain "samp" in the filename... But, is there a way to say, "list all of the files that match "samp" <em>or</em> "examp"?  </p>
  
  <p>I already figured out that </p>
  
  <pre><code>ls ./files/ | grep samp examp 
  </code></pre>
  
  <p>doesn't work... </p>
