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 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 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
