This book will train you to be a master in Bash, a technology that's more often used than understood. This book takes you through knowledge essential to a mastery of Bash.
Bash is so ubiquitous that we take it for granted that people know it, and under-valued as a skill because it’s easy to ‘get by’ with it. It’s my argument that the software community is woefully under-served when it comes to learning about Bash, and that mastering it pays massive dividends, and not just when using Bash.
Either you are given:
• Impenetrable man pages full of jargon that assumes you understand far more than you do
• One-liners to solve your particular problem, leaving you no better off the next time you want to do something
• Bash ‘guides’ that are like extended man pages - theoretical, full of jargon, and quite hard to follow
All of the above is what this book tries to address. It is divided into four parts:
1) Core Bash
