This book is a must have for those that want to get right at it putting good & meaningful scripts together. Plenty of great examples and explains in such a easy to follow format.

This is book is really worth having. As with any knowledge you use, the stuff you learned and don't use tends to get swapped out of memory (your head). You end up using the same ways and tools over and over, even though they might not be the best way or may not even get the job done.The author here has really captured a style that brings a newbie up to speed but also has enough depth to be a mental reference for old pros. I've not seen another that does that, and I think it's his get-to-the-point style and non-trivial examples that do it. I find I go back to it for review often. I don't have to wade through pages of silly newbie talk to find some help, and the depth taught me some new things and new uses!Most other books seem to fill up pages with a copy of the man pages, template style wording, and stuff you can find repeated everywhere. This book doesn't do that. Instead, his uses give enough to get the sense of how to use a tool like sed or awk or any of the others while also giving examples that "as is" can come in handy - because it seems to draw from real-world uses and needs. So in that sense, it even has a second benefit to offer.I'm very happy with the book. It's by a real programmer who is good at what he does, and doesn't talk 'down' to the reader. It's also enjoyable to read, without the pedantic approach most others take. I waited a long while to review just to see if it was "love at first sight" or something more. It has proven itself many times to this day, so I am comfortable giving it some praise and a recommendation!
