homebrew（报管理器）、yaml、apt-get、apt是包管理工具；

zsh、bash都是解释器，是shell语言的解释器，都是服务于shell语言的，它们之间的区别是，zsh能够很好的兼容bash，zsh更优雅；

zsh与bash：

切换bash：chsh -s /bin/bash
切换zsh：chsh -s /bin/zsh

zsh读取的配置文件：~/.zshrc
bash读取的配置文件：~/.bash_profile
如果在将解释器由bash换成zsh的时候，如果不想重新配置~/.zshrc的话，可以直接执行:
source ~/.bash_profile
这样就可以读取配置了
