I knew the reputation editor, I was far from disappointed. The book is always on hand. It is very helpful for those who may like me, of little problems of memory. It must be said that there a profusion of orders that are not used every day. Personally, I bought the entire proposed by amazon, and I do not regret. His two accomplices are "Regular Expression" and "Bash" from the same publisher, they are of the same ilk. These books are small format and do not take up space on the desk but quickly become serious collaborators who will not disappoint you.
