安装oh my zsh，并按安装插件zsh-autosuggestions自动补全命令

git clone https://github.com/ohmyzsh/ohmyzsh.git ~/.oh-my-zsh
cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
vim ~/.zshrc
source ~/.zshrc
sudo apt install zsh
chsh -s /bin/zsh

修改.zshrc的时候将ZSH_THEME=“gnzh”

git clone https://github.com/zsh-users/zsh-autosuggestions
vim ~/.zshrc
source ~/.zshrc
