Title: Not worth your time or money
Review: This book is very badly written. It is horrible!! Not enough detail to truly learn the commands and the author has tried to cram in a lot of subject matter into one book but he has missed the needed detail. Very few exercises to cover most important topics. I had to give him 1 star because the system would not let me pick 'no star'. Some engineers just can't write and this author is one of them.
Is the review positive or negative?
