title: Get the Perl rename utility instead of the built-in rename
body: <p>Many sites (including various SO articles) talk about using "rename" using Perl expressions to rename files.</p>
  
  <p>This would be perfect, but apparently this is not the rename utility I have, and none of these articles seem to comprehend that there are multiple versions of "rename" and I can't seem to find where to get version that accepts Perl expressions.</p>
  
  <p>How can I get my hands on the more powerful rename utility mentioned <a href="http://linuxaria.com/howto/mass-renaming-files-on-linux?lang=en" rel="noreferrer">here</a>, <a href="http://www.tecmint.com/rename-multiple-files-in-linux/" rel="noreferrer">here</a>, and <a href="https://stackoverflow.com/a/6329558/1542702">here</a>?</p>
  
  <p>I'm running Fedora 20. My current rename command is from the <code>util-linux</code> package and apparently I need the Perl version, which is better. </p>
