The Linux Command Line, 3rd Edition

The Linux Command Line isn't just a reference manual. It's a complete education on how Linux really works. From your first tentative keystrokes to writing powerful shell scripts, you'll build the confidence and understanding to make your system work for you. Now in its third edition, this best-selling guide has been fully updated with modern examples, nearly 40 pages of new content, and downloadable scripts from LinuxCommand.org. Used in more than a thousand classrooms and libraries worldwide, it has helped over 150,000 readers gain fluency and confidence in Linux.
