默认的bash环境需要配置的太多，我直接选用zsh套餐了，因为默认的风格我觉得很舒服，就没有修改。

# 安装zsh
sudo apt-get install zsh
zsh --version

# 安装oh-my-zsh，需要先安装好git
sh -c "$(wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"

# 配置一些插件
# git z 这两个插件已经自带，只需要配置上就可以了

# zsh-syntax-highlighting
# 高亮语法，如图，输入正确语法会显示绿色，错误的会显示红色，使得我们无需运行该命令即可知道此命令语法是否正确
git clone https://github.com/zsh-users/zsh-syntax-highlighting ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

# zsh-autosuggestions
# 显示之前运行的命令, 按<control + e>即可补全，或者按右键→即可补全
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

# 在.zshrc加上
plugins=(git z zsh-autosuggestions zsh-syntax-highlighting)

# source ~/.zshrc 生效
source ~/.zshrc
