Query: This should be titled Unix Made Difficult

I used this book for a Unix class in my local community college. This is the worst text book ever written, I got lost many times. It was difficult to find related text and difficult to keep pace throughout the course. I am a seasoned Linux user and Linux certified, but I recieved no help through this book. If you want to learn Linux, I would reccommend any book by Michael Jang. He writes in an easy and detailed manner. John Muster may teach Unix, but he is a terrible author, go back to english prep John or take a lesson from Michael Jang.
