title: Find all files ending in extension in bash
body: <p>Write a bash script accepting two arguments: directory and extension.
  The script must print to stdout the path of all files in directory (and,
  recursively, its sub-directories) with a name ending with extension. </p>
  
  <p>So far I have:</p>
  
  <pre><code>find {directory} -type f -name ' *.extension *
  </code></pre>
  
  <p>when I give it 2 args it doesn't seem to find anything. </p>
