1. Install homebrew
2. Install Git and bash-completion: brew install git bash-completion (Note: If this install fails with a 404 error, and you already have git installed, just remove the git part of this brew install)
在我电脑上已经安装了git,现在只需要安装bash-completion即可，执行如下命令
uxiaolei@duxiaoleideMacBook-Pro:~$brew install bash-completion Updating Homebrew... ==> Auto-updated Homebrew!

查看bash-completion安装信息

4. 主要看bash-completion安装信息中Caveats下面的提示，将如下内容添加到~/.bash_profile中，执行如下命令：
duxiaolei@duxiaoleideMacBook-Pro:~$echo "[[ -r "/usr/local/etc/profile.d/bash_completion.sh" ]] && . \"/usr/local/etc/profile.d/bash_completion.sh\"" >> ~/.bash_profile duxiaolei@duxiaoleideMacBook-Pro:~$tail -n 1 .bash_profile [[ -r /usr/local/etc/profile.d/bash_completion.sh ]] && . "/usr/local/etc/profile.d/bash_completion.sh" duxiaolei@duxiaoleideMacBook-Pro:~$source .bash_profile
5. 在source完bash_profile 加载完环境变量后，切换到git 目录下执行git 命令可以看到，git 已经支持自动补全
