All Sys Admins should own this,
Verified Purchase(What is this?)
This review is from: Unix Shell Programming (Paperback)
I've lost count of the number of Sys Admins who have seen this book and scoffed at the awful 70's artwork on the cover, thinking that this couldn't possibly be relevant reading material for the 21st century. However, once I show them why it's such a good book, it invariably ends up living permanently away from my desk. In fact, I'm only writing this review after discovering that yet another copy of mine has wandered off permanently.
You see, apart from being an incredible introduction to Unix shell scripting, it also has an easy-to-understand explanation as to how the Unix shell itself processes the commands you give it. For that reason, all Sys Admins should read this book, even if shell scripting isn't their thing. It only covers the Bourne and Korn shells, but serious Unix shell programmers wouldn't ever use anything else anyway.
An essential purchase.
