首先我们安装zsh，并切换默认的shell为zsh，之后重启进入zsh

sudo apt-get install zshchsh -s /bin/zshsudo shutdown -r now

之后我们安装oh-my-zsh，因为网络的原因所以设置了代理

wget -e https_proxy=192.168.65.100:7890 https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.shchmod +x install.sh./install.sh

然后再安装zsh命令自动补全插件zsh-autosuggestions

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

之后编辑~/.zshrc文件，修改ZSH_THEME="simple"，并且在plugins里面添加zsh-autosuggestions配置

ZSH_THEME="simple"plugins=(git zsh-autosuggestions)
