Linux Command Line: Beginners Guide to Learn Linux Commands and Shell Scripting (Linux Administration Book 2) Kindle Edition

Linux Command Line by David A. Williams is another seemingly self-published Kindle book, and I am finding these to be a hit or miss. While the author does a decent job of explaining how Linux works, there were many careless errors in the code samples and some odd use of the English language. Granted it was a short read, and cheap at that, but it only really scratches the surface of the complex operating system.In the book, David breaks things down to 7 chapters. We have the Linux shell, how the command line works, the environment, package management, environmental variables, and shell scripting. For a beginner’s book this is not bad, though many of the early chapters explain more about how Linux works rather than how to use it (for example, the lengthy discourse on GRUB, which many users would not need to understand right off the bat). I did enjoy the chapter on using man and help and other commands to learn how the GNU apps work. This is stuff I already basically knew, but I could see it helpful to a beginner.However, there were many mistakes in the test. For example, all throughout there were example with “ls” being shown with a “1” (one) instead of a “l” (el). Like: “1s -1 testdir”. Not sure if the author is a 1337 hax0r or something, but I’m pretty sure “1s” doesn’t work on my distro.There were a few other errors, mostly misspelled variables or logical errors which could make the book confusing if you didn’t catch them. In addition, I noticed a few typos in text and odd use of the English language, but I can forgive this assuming the author is not a native English-speaker. That said, proper editing would have caught it.If you a reading on an electronic device, unfortunately a lot of the code is not displayed well, even on an Android tablet. I can’t fault the author too much, because this is a common problem, but even code samples that were short (and should fit fine on one line) were spaced or broken up oddly.So all in all not a horrible book but not great either. I feel like for starting Linux users you should get a book that will teach how to *use* Linux first, before trying to understand how it functions under the hood (though that is good too, at some point later). And even for understanding the OS, this book is not very in-depth either. For the price, if you got free on Kindle Unlimited, I guess it’s not a complete waste of money but your time may be more well spent on better books. Just my 2 cents.

A waste of money. A technical book should be technically correct but the language structure of this book is distracting to the point of being insulting. Misspelled words, incorrect punctuation, incomplete sentences, and atrocious grammatical structure abound. That alone is enough to make this almost impossible to use as a learning instrument. I have 15+ years teaching IT and now need to learn Linux. This is not a book that will help that endeavor.The author has a "conversation" about something which is oftentimes not really on topic, shows a command line, may add a few parameters, and moves on to the next conversation or topic. No real explanation about the command or why you may want to use it for whatever the sometimes indistinguishable subject happens to be at that time. I would try to explain more of what is wrong but it it difficult to define "vapor" until you have seen it. Returning for a refund. I would recommend: "Introduction to the Command Line" (search Amazon for "B0BXN6QNBR") OR - OR - OR "Linux All-In-One For Dummies" (search Amazon for "1119901928").

The book has multiple mistakes. It is also too basic. It is more like an overview of command line. You can finish the book in a day and still not feel comfortable with command line. It lacks examples for you to try.

Works as promised. Indoors we use one multi connect to charge two Android phones with differing usb requirements.The other, thanks to the long extension cable is permanently in the car to charge an iPad and a large Android pad for back seat passengers.
