title: Moving files from directory and all subdirectories
body: <p>Is there a command that list all files in the directory and subdirectories? For example, when I am cleaning out my <code>~/Download</code> directory, I would like to move all the movie files to a specific directory.</p>
  
  <p>If I try this:</p>
  
  <pre><code>mv *.avi Directory
  </code></pre>
  
  <p>the avi files in subdirectories will not be moved. Is there a way to do this?</p>
