Query: Unix from the inside looking out

Funny, unorthodox, well organized, this book is a great survey of the unix family of OSes, useful both for newcomers to the system with basic computing familiarity & for those who (like me) have used & learned unix haphazardly for years.The first chapter, rather than teaching you frequently-used commands & their options, describes how to find & decipher documentation! The heart (or possibly the lymphatic system) of unix is figuring stuff out for yourself --not an easy matter if you don't know how to find out what you want to know or interpret what you've found. If you've ever stared at a man page, wondering what was wrong with your brain that you couldn't understand a word of something so detailed & apparently written in English, this book is for you!Subsequent chapters describe files (everything in unix is a file), processes, redirection & pipes, networking, regular expressions, shells, etc. --a holistic overview of unix as a complete system.
