title: removing backslash with tr
body: <p>So Im removing special characters from filenames and replacing with spaces. I have all working apart from files with single backslashes contained therein. 
  Note these files are created in the Finder on OS X </p>
  
  <pre><code>old_name="testing\this\folder"
  new_name=$(echo $old_name | tr '&lt;&gt;:\\#%|?*' ' ');
  </code></pre>
  
  <p>This results in new_name being "testing hisolder"
  How can I just removed the backslashes and not the preceding character?</p>
