A really excellent book.

It could be described as a series of working examples of

Bash shell one-liners, and short scripts. The examples are clear,

and don't seem invented just for the book, but rather are useful,

even inspiring.

The writing and explanations are great, and build up your skills as

you read.

It is also fairly comprehensive in scope, covering Bash itself

and many small Unix-y programs (ls, find, sed, awk etc.)

This is not a glorified manual. Perhaps other books by say

authors Shotts or Robbins & Beebe, might usefully complement it in that

area?

Most of all it conveys a sense of 'how to think' in Bash, the

spirit of it. Which, speaking for myself at least, may not

be obvious despite even years of use.

If you need to seriously use the command line on Linux/Unix/MacOS,

I highly recommend this.

As a book author myself, I understand how difficult it is to complete a technical publication. I hadn’t worked with Linux for a while, and I desperately needed a refresher.

That said, Daniel J. Barrett has done a great job explaining and demonstrating Linux command-line techniques, and his book most definitely helped me get back into the groove.

With Efficient Linux at the Command Line, Daniel has written a good book, and I’d go as far as to say it’s a great book.

At 432 pages, it's a fairly lean book by technology realm standards, but I’d go for quality over quantity any day. The book is also written so well, that you could use it as a highly effective reference, so you don’t have to memorize all the command line gems you’re bound to learn about. If I have a problem or a question that I can't resolve, I can simply turn to the index and find what I need.

Daniel’s well researched and written book reminds me why even though we have the internet, with so much information at our fingertips, there’s no substitute for a book written by an up to date, experienced and highly knowledgeable professional.

I'd expected this title to be a collection of handy tips and tricks to boost your command line skills. Sure enough, the book does include those.

But it also does an exceptional job of breaking down each command and option, giving you a comprehensive understanding of what each command does.

Some important tidbits of Unix/Linux theory and explanations of how shells and processes work here and there. Certainly a "must have" for anybody serious about deepening their understanding of the Linux OS

I've been using Linux Mint for about 7 years and have read several books on the command line. This book really helps boost me to the next level and greatly increases my efficiency. I particularly liked the method he offers to move quickly and with ease into folders many levels deep. In addition the pushd and popd commands are saving me a lot of time. I feel like I've certainly gotten my money's worth and I am only on page 67 of 230. I love the many concrete and practical suggestions.

This book gives a lot of great information on Linux. If you need to increase your Linux command line skills, this book is a great starter.

Lots of great tips, tricks, and insights into Linux. There are a few excellent sections on building complex commands. Beginners transitioning to intermediate and intermediate Linux users will likely get the most out of this book.

light to read but not much is explained...In some cases explanations are arguably not precise/clear.

This is a very clear logical book that is a real help for those wanting to learn more about the

command line. Most Linux users are in a sense helpless: they know how to use the nice friendly

GUI ("windows") interface in Ubuntu for example but that's it. That's fine most of the time - except

when things are not going well and then some command line skills are needed because an application

is not working and immediate help is not available. Instead of feeling helpless one can use some basic

command line skills to get things back on track.

It is not commonly appreciated that the"black box" GUI provided by the big two OS providers

fails to give the user the same ability to fix things that Linux users enjoy. There is a vast amount of

information about Linux and users can find out how it works if they are curious. The big two OS

cannot be looked at in depth by their users. Linux is open source.

Anyway, I can recommend this book as a superb text for both learning and getting a better

understanding of how to use the command line in Linux.

Ce livre permet de faire des progrès très significatifs dans la manipulation des commandes linux. C'est un livre extraordinaire bourrée d'astuces. Si vous regardez avec envie les anciens utilisateurs de linux manier avec dextérité les commandes linux, une fois que vous aurez appris ce livre je pense avec certitude que vous pourrez leur donner des leçons si vous avez tout retenus. L'avantage c'est qu'il n'est pas trop épais et vas droit a l'essentiel. C'est le livre sur linux le plus intéressant que j'ai lu. Ce livre ne se contente pas d'expliquer comment marche une commande , il montre comment les enchevêtrer entre elles pour rendre votre saisie hyper efficace. Il a le mérite de vous donner plein d'idées.

Je conseille en plus l'achat d'un autre livre : "Le Guide de survie Linux - 2e édition: L'essentiel du code et des commandes" qui liste toutes les commandes linux et détaillant leur utilisation.

Avec ces 2 livres vous serez le roi de la ligne de commande, pas besoin d'aller regarder ailleurs.

Bastante bueno para mejorar habilidades en la terminal y bash en general. Merece la pena comprarlo!!

I think this book succeeds at what it sets out to do.

The author is a good writer and explains everything in a very pedagogic way.

For a relatively short book there is a lot of information to take in. It's probably best to read it bit by bit in front of a computer, so you immediately can try out the examples one after one, and really practice and get a feel for them. Else you will probably forget a lot of it pretty quickly.

Be aware that due to the often cryptic syntax of Linux/UNIX commands, especially when combing them, the more advanced stuff often looks almost incomprehensible. It will certainly help to be a more experienced user to get something out of those parts and concepts.

Still, I'm pretty sure this is one of the best books about the command line.

O'Reilly have been releasing some real stinkers over the last few years. Seems that almost anyone who can spell the app or framework or whatever it is, qualifies to write a book about it and O'Reilly will happily release it and charge 40UKP for you to find out that its actually junk.

This book is certainly not in that category! This is the proverbial hidden gem, a book you won't want to put down because every page rewards you with something interesting or useful, oftentimes both.

I'd been a reasonably proficient shell user for more years than I would care to admit but always knew that there was more to learn and smarter ways to do things. This was exactly the resource I was looking for, The material follows a perfect gradient between easy and useful but tracks you toward more complex but insanely useful.

The explanations are fantastic. The author has the knack of being able to describe whats going on in a way that connects with the reader and hammers home the learning.

I'm a fan of this book and hope O'Reilly take heed and try to use this one as a template going forward (if you are going to charge > 40UKP for a book, it really should be decent).

If you are looking to level up your Linux shell game, this is the one to buy.
