This book reproduces the content of Linux support (the famous man) without providing any added value. He has no interest if we installed the entire repetoire man (/ usr / share / man), and it does not in any case to understand how to manage their Linux system, contrary to what may suggest the Table of Contents and the comment of the editor. The chapters on tools emacs, vi, sed, ..., are only introductions without interest for those seeking assistance with their use.
