Book review: The Linux Command Line, by William E. Shotts

No Starch Press kindly sent me a copy of The Linux Command Line to review a little while back. I already posted a review on Amazon, but figured that the book might be of interest to people here, too. Read on for a fuller, more detailed review.

The Linux Command Line book cover

Although point-and-click graphical interfaces may initially seem more intuitive, many tasks are much better suited to command line applications. I first started using the command line mostly out of necessity, back in the days when desktop Linux was still rather unfriendly to new users. After a little while, I had gained enough familiarity with the system to start cooking up useful combinations of commands for myself, without having to constantly copy them from books or webpages. I soon found myself preferring to use the command line for many tasks – it became quicker and easier than using a GUI. I even gained a rudimentary understanding of how the command line itself works, and started using a few of its more advanced features. And that’s the stage I’m at now – I know how to use a range of useful commands, and can achieve a lot using the command line in an efficient and satisfying manner. But anything beyond the basics of powerful concepts like regular expressions, commands like sed and find, and the ins and outs of Bash scripting, are still a bit of a mystery to me. If I need to do anything fancy, I fall back on doing it manually, or else write a Python script, simply because I’m more comfortable doing things that way. “The Linux Command Line” is a very useful book, in that it has helped me to take my command line skills to the next level, making it much less of a necessity to develop my own tools.

Something for every eventuality

As with most books from No Starch*, the book is beautifully presented and well written. All of the common command-line tasks are covered, many of them in detail, and there are a number of nice, friendly introductory chapters (pdf) for those who have never used a command line before. But the real value, for me at least, came from the treasure trove of more obscure commands that the book contains. UNIX is a very mature system, and practically every computer-based task you can think of can be performed using existing command line tools. Indeed, on first opening the book to a random page, I immediately found a tool to automatically format text files in a rather specific way, a task that I had been wasting quite a bit of time doing manually (and hadn’t yet encouraged myself to automate). Even old hands will be able to find something new in here, such is the diversity of the topics covered.

Other highlights include a guide to programming in Bash, which cuts through the quirks of the scripting language in a rather transparent manner, and a number of chapters on the common system admin tasks that occupy most peoples’ command line time. The latter part is slightly hampered by being rather distro-specific in places, choosing only to cover Debian (Ubuntu) and Red Hat (Fedora) where non-generic commands must be used. A couple of other distros could have been added to the list without too much fuss, allowing the book to serve as a useful cross-distro reference.

Covering all the bases

And that brings us to one of the difficulties with books like this: Completeness. The cover’s promise of a complete introduction is a bold one, and Shotts can be forgiven for not providing a comprehensive guide to every last command; there are just so many of them, and they can get quite complex. Nevertheless, there are some interesting omissions here. Terminal-based text editors are extremely advanced, offering real productivity gains for programmers and other would-be command line users, but they go largely unmentioned. While a comprehensive introduction to emacs is certainly outside the scope of this book, it could at least have been mentioned! Only a brief introduction to vim is included, which suffices for basic text editing tasks. Additionally, important networking tools like SSH, which are vital for remote working and system administration, are covered only very briefly. In an ideal world, I would have liked to have seen a whole chapter with detailed information on SSH, tunnelling, and the like. This lack of total completeness, understandable though it may be, will leave some readers a little disappointed. Still, the majority of topics are covered in suitable depth to satisfy the majority.

It’s probably best to treat this book as an advanced introduction – reading it will introduce you to a whole range of useful tools, which you can then go on to learn more about using specialised documentation, or more focused technical manuals. The Linux Command Line will get you started, and quite a lot more, but you’ll eventually need to move to something more specific if you really need to delve into the murkier recesses of a certain command.


If you would like to start using the command line, improve your existing skills, or simply want to discover tools that you were never even aware existed, this book has everything you need, and I wholly recommend it. If you want to learn about the specifics of some particular command line tool, you’ll at least get a good introduction here, but you’ll eventually have to read its manual all the same.

* Including my own; I’ve authored two titles with them, and love the house style to pieces.
