Zsh是一款强大的虚拟终端,既是一个系统的虚拟终端,也可以作为一个脚本语言的交互解析器。它相对Bash (not by default, only if you issue "emulate sh")有如下优点:

  • 更快
  • 优化了的自动补全
  • 优化的模式识别
  • Improved array handling
  • 全面可定制




$ echo $SHELL

Template:Package Official官方维护仓库中,可以和其他类似软件一样安装 .



$ zsh

将会看到 zsh-newuser-install,新手向导将可以帮你完成一些最基本的配置。若想跳过,按Template:Codeline键退出.


Template:Filename文件中已列有zsh,则可以使用 Template:Codeline 来改变默认的终端——此命令不需要以根账户使用,但使用过程中需要使用根账户密码。 如果是从官方维护的仓库中安装Zsh,则Template:Filename已列有zsh。


$ chsh -s $(which zsh)
Note: 修改完后要重新登录才能见效


$ echo $SHELL
Tip: If you are replacing Template:Package Official, you may want to move some code from Template:Filename to Template:Filename (e.g. the prompt and the aliases) and from Template:Filename to Template:Filename (e.g. the code that starts your X Window System).


Tango-inaccurate.pngThe factual accuracy of this article or section is disputed.Tango-inaccurate.png

Reason: please use the first argument of the template to provide a brief explanation. (Discuss in Talk:Zsh (简体中文)#)

At login, Zsh sources the following files in this order:

This file is sourced by all Bourne-compatible shells upon login: it sets up an environment upon login and application-specific (/etc/profile.d/*.sh) settings.
This file should contain commands to set the command search path, plus other important environment variables; it should not contain commands that produce output or assume the shell is attached to a tty.
This file is generally used for automatic execution of user's scripts.
This file is generally used for automatic execution of user's scripts.

At logout it sources Template:Filename, which is used for automatic execution of user's scripts.


用于定制的配置文件 ~/.zshrc

Although Zsh is usable out of the box, it is almost certainly not set up the way you would like to use it, but due to the sheer amount of customisation available in Zsh, configuring Zsh can be a daunting and time-consuming experience.

Included below is a sample configuration file, it provides a decent set of default options as well as giving examples of many ways that Zsh can be customised. In order to use this configuration save it as a file named Template:Filename. You can then apply the changes without needing to logout and then back in by running:

$ source ~/.zshrc

简单的 .zshrc






The above configuration includes ssh/scp/sftp hostnames completion but in order for this feature to work you will need to prevent ssh from hashing hosts names in ~/.ssh/known_hosts (Warning: be aware that this makes your computer vulnerable to "Island-hopping" attacks). In that intention, comment the following line or set the value to "no": Template:File And move your ~/.ssh/known_hosts somewhere else so that ssh creates a new one with with un-hashed hostnames (warning: previously known hosts will thus be lost).

For autocompletion with an arrow-key driven interface, add the following to: Template:File

For autocompletion of command line switches for aliases, add the following to: Template:File


Zsh does not use readline, instead it uses its own and more powerful zle. It does not read Template:Filename or Template:Filename. zle has an emacs mode and a vi mode. By default, it tries to guess whether you want emacs or vi keys from the $EDITOR environment variable. If it is empty, it will default to emacs. You can change this with bindkey -v or bindkey -e.

To get some special keys working: Template:File

Alternatively, you can convert /etc/inputrc for Zsh: Template:File

Note: To get the proper sequences for certain key combinations, start Template:Codeline or Template:Codeline without any parameters and press them; they should then be printed in the terminal. Both can be closed again via Template:Keypress+Template:Keypress.






There is a quick and easy way to set up a colored prompt in Zsh. Make sure that prompt is set to autload in your Template:Filename. This can be done by adding these lines to:


You can now see available prompts by running the command:

$ prompt -l

To try one of the commands that is listed, use the command prompt followed by the name of the prompt you like. For example, to use the "walters" prompt, you would enter:

$ prompt walters

Customizing your prompt

In case you are dissatisfied with the prompts mentioned above(or want to expand their usefulness), zsh offers the possibility to build your own custom prompt. Zsh supports a left- and right-sided prompt additional to the single, left-sided prompt that is common to all shells. To customize it, the following variables can be used:

Prompt variables

The computer's hostname(truncated to the first period)
The computer's hostname
The current tty
The return code of the last-run application.
The prompt based on user privileges (Template:Codeline for root and Template:Codeline for the rest)

For the options mentioned above: You can prefix an integer to show only certain parts of your working path. If you entered Template:Codeline and found yourself in Template:Codeline it would show Template:Codeline. This can also be done with negative integers: Template:Codeline using the same directory as above would show Template:Codeline.

%U [...] %u 
%B [...] %b 
 %{ [...] %} 

Zsh has a different approach to setting colors on the terminal than the one depicted here. First you write in your Template:Codeline:

autoload -U colors && colors

Following commands would now produce the color escape sequence needed to set the requested color when the prompt is printed:

will set the textcolor(red,green,blue, etc)
will reset the textcolor to white

It is useful to put these commands in Template:Codeline}.


To have a two-sided prompt you could write:

PROMPT="%{$fg[red]%}%n%{$reset_color%}@%{$fg[blue]%}%m %{$fg[yellow]%}%1~ %{$reset_color%}%#"

It would equal(without colors):

username@host ~ %                                                         [0]

Advanced .zshrc files

One could also find a great way to manage its Zsh configuration by using Oh-my-zsh created by Robby Russel which contains a lot of user contributed plugins and themes but most importantly a great community of more than 900 forks on github.

This is an example of a more advanced Template:Filename.


There are many more ways that you can customise Zsh, obviously far too many to list here, see the Zsh manual for more information.




Occasionally you might want to have some settings applied globally to all zsh users. The zsh wiki tells us that there are some global configuration files, for example Template:Filename. This however is slightly different on ArchLinux, since it has been compiled with flags specifically to target Template:Filename instead.

So, for global configuration use Template:Filename, not Template:Filename. The same goes for Template:Filename, Template:Filename and Template:Filename. Note that these files are not installed by default, so you need to create them yourself if you want to use them.

The only exception is zprofile, use Template:Filename instead.


Zsh always executes Template:Filename and Template:Filename so do not bloat these files.

If the shell is a login shell, commands are read from Template:Filename and then Template:Filename. Then, if the shell is interactive, commands are read from Template:Filename and then Template:Filename. Finally, if the shell is a login shell, Template:Filename and Template:Filename are read.



按照Zsh#Making Zsh your default shell的方法改变默认虚拟终端,把zsh替换为bash即可恢复默认虚拟终端为bash。


Warning: 若上述步骤失败,将引发众多问题,所以请务必严格执行之。

若没按照上面所述去做,还可以用另外的方式改变默认虚拟终端,方法是以根用户身份修改 /etc/passwd 例如:


username:x:1000:1000:Full Name,,,:/home/username:/bin/zsh


username:x:1000:1000:Full Name,,,:/home/username:/bin/bash
