The Linux Command Line, 3rd Edition

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 isn’t a relic of the past—it’s the key to real computing power. With it, you can take control of your system, automate tedious tasks, and understand exactly what your computer is doing. That’s why more than 150,000 readers have turned to The Linux Command Line. Now in its third edition, this best-selling guide has been fully updated with nearly 40 pages of new material, modernized examples, and downloadable scripts from LinuxCommand.org. Everything you need to know about a command is in the man pages—and they’re an extraordinary resource. But they’re not always the fastest way to learn. When you just want to use a new command, or squeeze more power out of an old favorite, it helps to have an expert guide you along. That’s what William Shotts does in this book: he shows you not just what a command does, but how to make it work magic for you. Think of Shotts at your side saying: “Watch this. Here’s how you really use it.” Suddenly, you’ve got superhuman strength at the terminal. You’ll discover how to: Navigate the filesystem, create and manage files, and configure your environment Chain commands, redirect input/output, and wield regular expressions Administer processes, install packages, and work with networking tools Edit files with Vim, the classic Unix text editor Write shell scripts to automate tasks and build your own tools Harness powerful utilities like grep, cut, sed, and tar to process text and data Manage filesystems and storage devices Compile programs from source code Shotts writes with rare clarity and a touch of humor, making even complex concepts approachable and practical. Whether you’re migrating from another platform, managing servers, or hacking on a Raspberry Pi, this book will change the way you interact with your computer. Just don’t be surprised if your mouse starts to gather dust.
