Title: If you already know some Unix, forget this book
Review: If you already know a little bit of Unix or Linux or other Unix-variants, this book is way too "introductory" for you. It covers stuff like how to login and run ls, cp and mv. As another example, see the section on backing your computer. It talks about using find and tar, but nothing about dump and restore and backup strategies.Overall, too much scratching the surface and not enough in depth information for real Unix users.
