title: rename command is not overwriting as it should by default, how do I force overwrite?
body: <p>I have a bash script that uses the rename command as follows:</p>
  <pre><code>sudo rename 's/^(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})/Date-$1-$2-$3__Time-$4:$5:$6/' 2019*
  </code></pre>
  <p>According to the rename man page the command should overwrite by default and not overwrite by using the -o flag. But when I run the script it is not overwriting existing files. However I get an error thrown back and the duplicate files do not get any other processing done by the script.</p>

  <p>Frustrated, I tried to just use the mv command but gives me a different error:</p>
  <blockquote>
  <p>mv: target '20190710222433.WAV' is not a directory</p>
  </blockquote>
  <p>So I added a / and get the same error. Any advice?</p>
