Linux Command Bible 3e

By the time I bought this book, I had already read a lot of online resources about bash scripting, and I had already been using linux for two years. I had even read most of the A-plus certification book on Linux. Despite that, I was constantly struggling to write bash scripts that worked, this is because so much of the free online documentation on bash scripting is confusing and incomplete. Even when consulting co-workers, they too could not explain why so many things I tried to code in a bash script did not work. That's when I decided to buy this book.The "Linux Command Line and Shell Scripting Bible" cleared up a lot of problems that have been plaguing me for a long time now. I wish that I had started to learn bash scripting with this book, it could have saved me a lot of time. I would highly recommend this for anybody who will use linux.Let me list some things this book explained to me that I struggled with for years prior:- When is a subshell made, what are the implications of that, how does variable scoping come into play.- how can you create, manipulate, and pass around arrays in bash- how does the "return" statement behave in functions, how to use that in an if statement- how can you do math in bash- the differences between [ ] and Here are some other things I love about this book:- it has an excellent explanation of how you could parse a command line that follows a complicated pattern like "mycommand --longopt -a -bcf input.txt -- foo bar zop". Before I picked up this book I thought that would be too difficult to do in a bash script.- It explains how to easily create GUI interfaces for your script.- It has one of the best explanations for sed and gawk I have ever seen.Throughout the entire book, everything said is clear and easy to understand, and the authors give you ample examples to demonstrate the point. While the thickness of the book is a bit intimidating, you will find that you can read it pretty fast because a lot of those pages are full of clear examples that you can read quickly.Yet again I highly recommend it.

I have been using Linux on/off for a long time now. Favorite distro is Manjaro KDE. I bought this book to improve my bash scripting and use it as a future reference. I find the book to be easy to read. Everything is well explained and easy to follow. Decided to start reading the book from the beginning in my attempt to identify and fill in the gaps. In my opinion, this book is good for all levels. I am happy with this purchase.

This volume is the "perennial" publication of choice for the programmer at his daily grind. Some folks can make do with just the UNIX "Man" pages. Some folks make do with peeking over other mature programmers shoulders. There are "Visual learners' and "Aural Learners." Now what if the reader is a non-distinct learner, hardware oriented, all fingers and no thumbs? Fear naught. This is precisely the book to maintain one's sanity.Ye have graduated from Computer Assembler, Computer Tester, Computer Technician, Computer Programmer, Computer Administrator, Network Administrator, Computer Analyst, Computer Technologist, Computer Engineer, Systems Engineer, Cybernetic Engineer, but along the way the professional has forgotten most or all that was learned. This book shall bring the reader back prepared for the task at hand.Yes that dreaded "Command Line Interface", remember MS-DOS, Apple-DOS, PC-DOS, DR-DOS, UMSDOS, etc. After all these decades itsremains the way to have uninhibited firmware and system access. Nevermind a User must have hardware access, really now. Allow the basic machine language coding get the User into the system, network to get the job done.Does that computer at work and home have the User at its mercy? Buy this book, read it, internalize the contents, the User shall not ever fear coding again. Many successful Users have already re program their electronic calculators, tablets, and other ARM equipped devices to do more than just play games. There are UNIX, DOS, Windows, MacOS-X, and Linux operating systems. They all have one uninhibited access point...the "Command Line". And the future is Linux, because everything runs on Linux now! There are over 37,840 distributions, variants, editions, and versions of Linux operating systems. Linux is ubiquitious and universal. There is neither a best, nor perfect operating system, and Linux comes extremely close. This book will help the reader to understand how simple line commands can be arrayed to do complete instructions for most operating systems.Remember lest ye forgotten. The Chinese invented the first human binary calculating device. The English invented the first Analog electric computer. The Americans invented the first Digital electronic computer. The USA, Canada, and Australia together invented the world's first Quantum Relativity Computer that runs at Light Speed with cooling at the speed of sound! May your pursuit of excellence be fruitful.

This book is incredibly incredibly helpful I've just started getting into Linux and I've started also going to school to be a software developer I've read only 45 pages or so and I can already tell that it is going to be extremely helpful there is parts that are dated which is why it didn't get a full five stars such as using a live CD rather than a USB to boot onto your system aside from that it is great and I highly recommend it to anybody who plans to use Linux. I also recommend anybody who cares at all about privacy or control of their system to use Linux in general I don't even have Windows at the moment.

Thorough and comprehensive "Bible". Don't be intimidated by its sheer size. This paper-backed book contains a wealth of information in a very easy to digest format. I have some experience with Linux but this books really gets into the meat of the matter. I was familiar with command line prompts but shell scripting is new (and exciting) to me. Well worth the price for so much valuable information. I'm taking my time going through the book in an attempt to let the information really sink in.
