Wicked Cool Shell Scripts: 101 Scripts for Linux, OS X, and Unix Systems by Dave Taylor and Brandon Perry, 2nd edition, no starch press (2017) is a book that can lift you up a notch in the super Unix techno-dweeb rankings. It’s that good.
Not everything you encounter in your life as a Unix geek is going to rate being called “wicked cool”. Near as I can tell, this includes some of Tom’s of Maine toothpaste along with some kids’ toys, certain WordPress plugins, and the scripts in this book. The scripts are wicked cool because they can make you considerably better and more productive at using and managing your Linux systems.
