The command-line interface is making a comeback. That's because developers know that all the best features of your operating system are hidden behind a user interface designed to help average people use the computer. But you're not the average user, and the CLI is the most efficient way to get work done fast. Turn tedious chores into quick tasks: read and write files, manage complex directory hierarchies, perform network diagnostics, download files, work with APIs, and combine individual programs to create your own workflows. Put down that mouse, open the CLI, and take control of your software development environment.

No matter what language or platform you're using, you can use the CLI to create projects, run servers, and manage files. You can even create new tools that fit right in with grep, sed, awk, and xargs. You'll work with the Bash shell and the most common command-line utilities available on macOS, Windows 10, and many flavors of Linux.

Create files without opening a text editor. Manage complex directory strutures and move around your entire file system without touching the mouse. Diagnose network issues and interact with APIs. Chain several commands together to transform data, and create your own scripts to automate repetitive tasks. Make things even faster by customizing your environment, creating shortcuts, and integrating other tools into your environment. Hands-on activities and exercises will cement your newfound knowledge and give you the confidence to use the CLI to its fullest potential. And if you're worried you'll wreck your system, this book walks you through creating an Ubuntu virtual machine so you can practice worry-free.

Dive into the CLI and join the thousands of other devs who use it every day.

What You Need:

You'll need macOS, Windows 10, or a Linux distribution like Ubuntu, Fedora, CentOS, or Debian using the Bash shell.

命令行界面正在卷土重来。这是因为开发人员知道，你的操作系统的所有最好的功能都隐藏在用户界面后面，旨在帮助普通人使用计算机。但你不是普通用户，CLI是快速完成工作的最有效方式。把繁琐的杂事变成快速的任务：读写文件、管理复杂的目录层次、执行网络诊断、下载文件、使用API，以及结合单个程序来创建你自己的工作流程。放下鼠标，打开CLI，并控制你的软件开发环境。

无论你使用什么语言或平台，你都可以使用CLI来创建项目，运行服务器，并管理文件。你甚至可以创建新的工具，与grep、sed、awk和xargs相适应。你将与Bash shell和macOS、Windows 10和许多口味的Linux上最常见的命令行实用程序一起工作。

无需打开文本编辑器即可创建文件。管理复杂的目录结构，并在你的整个文件系统中移动，而无需触摸鼠标。诊断网络问题并与API进行互动。将几个命令串联起来以转换数据，并创建你自己的脚本以自动完成重复性任务。通过定制你的环境，创建快捷方式，并将其他工具集成到你的环境中，使事情变得更快。实践活动和练习将巩固你新发现的知识，使你有信心充分利用CLI的潜力。如果你担心你会破坏你的系统，本书将指导你创建一个Ubuntu虚拟机，这样你就可以无忧无虑地练习。

潜心研究CLI，加入成千上万每天都在使用它的其他开发者的行列。

你需要什么？

你需要macOS、Windows 10，或者像Ubuntu、Fedora、CentOS或Debian这样使用Bash shell的Linux发行版。
