Show/hide Terminal Script Service
My purpose was to create a script that would enable me to show/hide and open (if not running) the Terminal.app on Mac OS X so that once the script is installed, I can use a shortcut to run the script. Supported/Tested OS X versions: OSX El Capitan, macOS Sierra
Installation:
Clone the repository on your computer
Double-click the script file once downloaded
It should ask you if you would like to install the service, Select Install Service.
Open System Preferences
KeyBoard > Shortcuts
In the Services part, you should find it at the bottom
Select the "New Terminal" option and click to add the shortcut you want :)
