powerlevel10k很香，启动终端后会有引导帮助你配置，不仅好看，而且启动速度还快不多说，

#首先：
git clone --depth=1 https://gitee.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

#然后
open ~/.zshrc 

# .zshrc中设置：
ZSH_THEME="powerlevel10k/powerlevel10k"

重新打开就自动出现配置页面，按照提示一步步设置之后就成功啦

欢迎加入powerlevel10k
