The Linux Command Line: A Complete Introduction

Book Description

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.

书名：Linux命令行：完整介绍

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.

Linux命令行 从第一次终端击键到用Bash编写完整程序，Bash是最流行的Linux外壳。在此过程中，您将学习一代又一代留着灰胡子、躲避鼠标的大师们传承下来的永恒技能：文件导航、环境配置、命令链接、与正则表达式的模式匹配等等。

除了这些实用知识之外，作者William Shotts还揭示了这些工具背后的理念，以及您的桌面Linux机器从过去的Unix超级计算机那里继承下来的丰富遗产。

当你通读这本书的简短、易于理解的章节时，你将学习如何：

• Create and delete files, directories, and symlinks
• 管理您的系统，包括联网、包安装和进程管理
• 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
• 使用剪切、粘贴、grep、补丁和编辑对文本文件进行切片和骰子操作

一旦你克服了最初的外壳震撼，你会发现命令行是与你的计算机进行交流的一种自然且富有表现力的方式。如果你的鼠标开始尘土飞扬，不要感到惊讶。
