Linux Command-Line Tips & Tricks is a hack collection for Linux command‑line warriors. Because of the shell's ancient history, BASH scripting has some odd programming constructs that are difficult to memorize. This book is a ready-reference for such archaic but crucial details. It is also at an advanced level. It assumes that you already know how to use the terminal and are adept at shell programming. It does not teach you the basics or try to be a comprehensive reference. It trusts your intuition and focuses on things that you are most likely to forget or be confused about. It devotes special attention to coding mistakes or unusual circumstances in which your script or command will fail.
Chapters
Most Linux books do a good job of describing expected behaviour. Very few of them focus on stuff that can go wrong. And, as everyone knows, if things can go wrong, they most likely will. Given that trillions of dollars of assets are managed by shell scripts, it is important to avoid all avoidable mistakes.
