Cleanup: The script styling practices.

Over time my scripting style practices have changed.
Up date these older scripts.

The variables should always have braces (makes compatibilty with other shells like ZSH easier).
Add additional lines in certain places.
Make comments proper sentences by making first letter upper case.
