Shell Scripting: How to Automate Command Line Tasks Using Bash Scripting and Shell Programming Paperback – September 17, 2015

Succinctly:In less than 100 pages, the author gets you up and running with [Bash] shell scripting. The entire book is precise, clear, and well structured. There is no divergence from the topic or the lessons, only short tips on common errors, style, and convention. In some cases I did look elsewhere to figure somethings out, but that was my own need for differentiated instruction. As such, I enrolled in the author's course on Udemy, which is cheap (link below).If, like me, you get distracted by implementation details and are looking for a book that will teach you shell scripting from scratch quickly (or quickly tie a bunch of disparate knowledge together), then this book is for you! I also highly recommend the Udemy course in addition to the book.Below is a reply to the author of "Shell Scripting", Jason Cannon, over at his course on Udemy [...]"Thanks for the this awesome course and your equally awesome book: "Shell Scripting"! I love that from pp 2 - 85 is basically no fluff or divergence from what you've set out to do: teaching shell scripting succinctly. I also love that I can switch in between your video lectures and the book, or go over sections from your video lectures in the book. Great flexibility and scaffolding for learning.It's really great that you've provided a straight forward and ​practical introduction to shell scripting. I will recommend this to anyone having the same problem as me with more traditional [Bash] scripting tutorials, which is that they have some amount of divergence from actual shell scripting. While I really am interested in things like Processes, Streams, and File Descriptors; I get really caught-up in the implementation side of things. I can focus on implementation later, as I progress in knowledge.So, again, thank you!"

I’ve been using linux for a few years now, I am far from an expert, but I k it how to google my way through an issue. I don’t like reading, and I always struggle to push myself to get through programming books. I got through this one in a weekend and it gave me enough knowledge to start creating scripts that have saved me enough time at work to start creating more scripts at work. Highly recommend it for guys like me.

This book is a great starting point for someone like me who already understands the basics of using bash commands, but wants to understand the often cryptic syntax of working shell scripts (your own or those you can find elsewhere). It doesn't assume a knowledge of basic programming skills, but if you've worked with python or some other scripting type language you will be able to understand the information more quickly.The examples were very good and easy to understand. I particularly like that they provide sample answers to the exercise questions at the end of each chapter.Minus one star only for not being quite as comprehensive as it could be, but still an excellent resource overall.

This book teaches exactly what it says: Shell Scripting . Clearly, easily, & with excellent warnings of common mistakes and pitfalls, and with clear, short Good Programming tips & advice.If you know some Unix/Linux Command Line, i.e., are able to use the Terminal, then I don't know a better book that expands your abilities and productivity than this book! Especially since it's as cheap as a bad cup of coffee!If you don't know Linux/Unix Command Line, or if you do and hate it, get the cup of bad coffee instead! 😉

I felt fairly knowledgeable about Linux commands but very weak at shell scripting, so I bought this book because it was rated so highly. It is phenomenal. It's extremely short and the text is big, but that is the best thing about it--every page is valuable and clear. This book is insanely practical and extremely understandable. I really understand shell scripting now. I did all the exercises and you should too. They are pretty basic but they give you the hang of shell scripts. Can't say enough about this book.

Let me start by saying this is a good book for shell beginners to start with, and I want to really give it 3.5 stars, but it is hard to like.I powered through it because people kept saying they learned something new after X years of programming, but that wasn't true for me. You guys need to read the Bash manual and really have your mind blown. Anyway:Pros: - Good introduction to scripting for complete beginners - Pretty Cover pictureCons: - Poorly formatted pages/code. Felt like they just hit upload on a word doc and didn't look at how it was formatted - Errors in the code. Small typos, forgetting to add a ! to the shebang a lot, etc. Obviously didn't run all of these examples - Only 84 pages long. Most of those are repeated code blocks and exercises. Felt like a resume bullet/link to the author's paid website - Suggests questionable practices (Parsing ls, echo instead of printf, not taking more advantage of builtins like $0 for the script name or mktemp for making tmp files, setting exit 0 on a test of exit 0 anyway, etc.) - Spends a long time talking about debugging but doesn't mention actually helpful tools like shellcheck, BATS, etc. - Doesn't really talk about when NOT to use a shell script - Also, this is all Bash based with hardly any mentions of portability. So it should just be called "Bash Scripting"All in all, the price is right if you have never scripted anything, but there are much better resources out there like Greg's Wiki, tldp, or even the Unix Stack Overflow

Estoy empezando a descubrir el mundo de Linux y este libro es una guía bastante práctica para el suelo scripting

A breath of fresh air among technical how-to books. Simple, clean explanations; easy to follow examples; and coding challenges with answers. All that's missing are rambling explanations, irrelevant information, and filler.

Good

Muy bien.

libro ben organizzato
