title: How to remove specific characters from a file name?
body: <p>I have bunch of files that need to have a (.) dot removed from the file-name. Eg. "Mr.-John-Smith.jpg" to "Mr-John-Smith.jpg". I don't have real experience with programming and know only html/css and a little javascript. I found another identical question here on stackoverflow, but what I gathered it was fixed on linux system and BASH was used. </p>
  
  <p>Anyways, if anyone could provide me a tutorial on which program to use for this and what code to execute in that program to make it happen I'd be grateful.</p>
