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 (or command line). Along the way you'll learn the timeless skills handed down by generations of experienced, 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.

你已经体验到了Linux计算机闪亮的、点击式的表面--现在潜入下面，用命令行的力量探索它的深度。

Linux命令行》带领你从最初的终端按键到在Bash中编写完整的程序，Bash是最流行的Linux外壳（或命令行）。在这一过程中，你将学习由几代经验丰富、避开鼠标的大师们传下来的永恒的技能：文件导航、环境配置、命令链、正则表达式的模式匹配等等。

除了这些实用的知识，作者William Shotts还揭示了这些工具背后的哲学，以及你的桌面Linux机器从过去的Unix超级计算机上继承下来的丰富遗产。

当你通过本书简短、易消化的章节时，你将学会如何。

  - 创建和删除文件、目录和符号链接

  - 管理你的系统，包括网络、软件包安装和进程管理

  - 使用标准输入和输出、重定向和管道

  - 使用世界上最流行的文本编辑器Vi编辑文件

  - 编写shell脚本，使普通或无聊的任务自动化

  - 用剪切、粘贴、grep、patch和sed对文本文件进行切分。

一旦你克服了最初的 "shell冲击"，你会发现命令行是一种自然的、富有表现力的与计算机交流的方式。如果你的鼠标开始积灰，请不要惊讶。
