Linux Command Line

A Complete Introduction
by William E. Shotts, Jr.

January 2012, 480 pp.
ISBN: 978-1-59327-389-7

You've experienced the shiny, point-and-click surface of your Linux computer—now dive below and explore its depths with the power of the command line.

The Linux Command Line takes you from your very first terminal keystrokes to writing full programs in Bash, the most popular Linux shell. Along the way you'll learn the timeless skills handed down by generations of gray-bearded, mouse-shunning gurus: file navigation, environment configuration, command chaining, pattern matching with regular expressions, and more.

In addition to that practical knowledge, author William Shotts reveals the philosophy behind these tools and the rich heritage that your desktop Linux machine has inherited from Unix supercomputers of yore.

As you make your way through the book's short, easily-digestible chapters, you'll learn how to:

  • Create and delete files, directories, and symlinks
  • Administer your system, including networking, package installation, and process management
  • Use standard input and output, redirection, and pipelines
  • Edit files with Vi, the world’s most popular text editor
  • Write shell scripts to automate common or boring tasks
  • Slice and dice text files with cut, paste, grep, patch, and sed

Once you overcome your initial "shell shock," you'll find that the command line is a natural and expressive way to communicate with your computer. Just don't be surprised if your mouse starts to gather dust.

"This is exactly what a Linux beginner needs to get up to speed quickly. The book goes beyond simply walking through all of the command line utilities, and ventures into the realm of theory and how things work together."
—Nicholas C. Zakas, Yahoo! (Read More)

"Anyone who reads this book and makes use of the examples provided will not be able to avoid becoming a Unix command line pro by the time they've hit the end of the book. It provides an excellent introduction to the command line that takes students from knowing nearly nothing to using impressively sophisticated commands."
—Sandra Henry-Stocker, ITworld (Read More)

"Shotts displays a genuine talent for explaining complex material."
—Bruce Byfield, Linux Magazine (Read More)

—Phil Bull, author of the official Ubuntu documentation (Read More)

"The book is a win and I happily give it a 10/10. Recommendation: Highest."

"There is so much information contained within this book, you're almost guaranteed to learn something. I did."
—The Linux Blog (Read More)

"A perfect companion to more remedial guides to Linux that touch on the command only briefly, and also a terrific bridge to deeper technical programming books. Highly recommended."
—Game Vortex (Read More)

"The Linux Command Line is pleasant to read. It has a light tone, while also getting down to business."
—John D. Cook, The Endeavor (Read More)

"A delightful read and you can hand it to a junior colleague or friend with more limited Unix shell exposure and be confident that they come back significantly shell-wiser and probably happier."

"Part of the power of the shell is in its almost infinite potential, which most shell users never master, but if you buy and then use The Linux Command Line to its fullest extent, your 'introduction' to the shell will be very impressive."
—James Pyles, A Million Chimpanzees (Read More)

"There's no system administration in the book, just making your way around a filesystem and the tools you need to get results. It's the kind of skills I think people lose out on when they boot to a graphical interface in Ubuntu, for example, and then never experience these tools."
—DragonFly BSD Digest (Read More)

"Shows you how to do just about everything you are ever likely to want to do with a computer using nothing but the command line and a plain text editor."
—Stephen Chapman, Felgall.com (Read More)
