Set up zsh on your Fedora system
|
|
||||||
======
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
For some people, the terminal can be scary. But a terminal is more than just a black screen to type in. It usually runs a shell, so called because it wraps around the kernel. The shell is a text-based interface that lets you run commands on the system. It’s also sometimes called a command line interpreter or CLI. Fedora, like most Linux distributions, comes with bash as the default shell. However, it isn’t the only shell available; several other shells can be installed. This article focuses on the Z Shell, or zsh.
|
|
||||||
|
|
||||||
Bash is a rewrite of the old Bourne shell (sh) that shipped in UNIX. Zsh is intended to be friendlier than bash, through better interaction. Some of its useful features are:
|
|
||||||
|
|
||||||
* Programmable command line completion
|
|
||||||
* Shared command history between running shell sessions
|
|
||||||
* Spelling correction
|
|
||||||
* Loadable modules
|
|
||||||
* Interactive selection of files and folders
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
Zsh is available in the Fedora repositories. To install, run this command:
|
|
||||||
```
|
|
||||||
$ sudo dnf install zsh
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
### Using zsh
|
|
||||||
|
|
||||||
To start using it, just type zsh and the new shell prompts you with a first run wizard. This wizard helps you configure initial features, like history behavior and auto-completion. Or you can opt to keep the [rc file][1] empty:
|
|
||||||
|
|
||||||
![zsh First Run Wizzard][2]
|
|
||||||
|
|
||||||
If you type 1 the configuration wizard starts. The other options launch the shell immediately.
|
|
||||||
|
|
||||||
Note that the user prompt is **%** and not **$** as with bash. A significant feature here is the auto-completion that allows you to move among files and directories with the Tab key, much like a menu:
|
|
||||||
|
|
||||||
![zsh cd Feature][3]
|
|
||||||
|
|
||||||
Another interesting feature is spelling correction, which helps when writing filenames with mixed cases:
|
|
||||||
|
|
||||||
![zsh Auto Completion][4]
|
|
||||||
|
|
||||||
## Making zsh your default shell
|
|
||||||
|
|
||||||
Zsh offers a lot of plugins, like zsh-syntax-highlighting, and the famous “Oh my zsh” ([check out its page here][5]). You might want to make it the default, so it runs whenever you start a session or open a terminal. To do this, use the chsh (“change shell”) command:
|
|
||||||
```
|
|
||||||
$ chsh -s $(which zsh)
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
This command tells your system that you want to set (-s) your default shell to the correct location of the shell (which zsh).

在 Fedora 系统上设置 zsh
|
||||||
|
======
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
对于一些人来说，终端可能会很吓人。但终端不仅仅是在黑屏中输入。它通常运行一个 shell，因为它围绕着内核调用。shell 是一个基于文本的界面，可让你在系统上运行命令。它有时也被称为命令行解释器或 CLI。与大多数Linux发行版一样，Fedora带有bash作为默认shell。但是，它不是唯一可用的 shell，你可以安装其他的 shell。本文重点介绍 Z Shell 或 zsh。
|
||||||
|
|
||||||
|
Bash 是对 UNIX 中提供的旧 Bourne shell（sh）的重写。通过更好的交互，zsh 旨在比 bash 更友善。它的一些有用功能是：
|
||||||
|
|
||||||
|
* 可编程的命令行补全
|
||||||
|
* 在运行的 shell 会话之间共享命令历史
|
||||||
|
* 拼写纠正
|
||||||
|
* 可加载模块
|
||||||
|
* 交互选择文件和文件夹
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
zsh 在 Fedora 仓库中存在。要安装，请运行以下命令：
|
||||||
|
```
|
||||||
|
$ sudo dnf install zsh
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
### 使用 zsh
|
||||||
|
|
||||||
|
要开始使用它，只需输入 zsh，新的 shell 在第一次运行时显示向导。该向导可帮助你配置初始功能，如历史记录行为和自动补全。或者你可以选择保持[ rc 文件][1] 为空：
|
||||||
|
|
||||||
|
![zsh First Run Wizzard][2]
|
||||||
|
|
||||||
|
如果输入 1，则启动配置向导。其他选项立即启动 shell。
|
||||||
|
|
||||||
|
请注意，与 bash 相同，用户提示符是 **％** 而不是 **$**。这里的一个重要功能是自动补全功能，它允许你使用 Tab 键在文件和目录之间移动，非常类似于菜单：
|
||||||
|
|
||||||
|
![zsh cd Feature][3]
|
||||||
|
|
||||||
|
另一个有趣的功能是拼写纠正，这有助于在混合大小写的情况下输入文件名：
|
||||||
|
|
||||||
|
![zsh Auto Completion][4]
|
||||||
|
|
||||||
|
## 使用 zsh 成为你的默认 shell
|
||||||
|
|
||||||
|
zsh 提供了很多插件，如 zsh-syntax-highlighting 和著名的 “Oh my zsh”（[在此查看其页面][5]）。也许你希望将其设为默认 shell，以便在你在开始会话或打开终端时运行。为此，请使用 chsh（“更改 shell”）命令：
|
||||||
|
```
|
||||||
|
$ chsh -s $(which zsh)
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
这个命令告诉你的系统你要设置（-s）默认shell 的正确位置（which zsh）。
