- commented out whattf-dt
- ignore standard error for find as some of the may will not exist
  on all systems I run this.
- now uses sudo internally. This is because most of the script's users
  will be running it from Finder and it's more user friendly if they
  don't have to wrap sudo around it by editing the short cut.

- since \b BASH escape isn't interpreted like it's done on Linux,
  we're using a simpler "will close in x seconds" message. This
  message is for users running the script from Finder as they would
  otherwise miss the messages from the script.
