安装 Zsh

sudo apt-get install zsh

安装后执行切换指令，切换到指定 Shell 后，进行重启。

chsh -s /bin/zsh

重启后会提示新用户程序。

This is the Z Shell configuration function for new users,
zsh-newuser-install.
You are seeing this message because you have no zsh startup files
(the files .zshenv, .zprofile, .zshrc, .zlogin in the directory
~).  This function can help you with a few settings that should
make your use of the shell easier.

You can:

(q)  Quit and do nothing.  The function will be run again next time.

(0)  Exit, creating the file ~/.zshrc containing just a comment.
     That will prevent this function being run again.

(1)  Continue to the main menu.

(2)  Populate your ~/.zshrc with the configuration recommended
     by the system administrator and exit (you will need to edit
     the file by hand, if so desired).

--- Type one of the keys in parentheses ---

根据自己的需求进行选择。

可以 q 或者 1 退出，因为后续安装 Oh My Zsh 会覆盖 zsh 的配置。
