使用git sta命令的时候，tab补全键按裂了都没反应，一般的linux系统下都会自动补全的，而mac并不会

好吧，百度了一下

1， 先安装bash-completion

brew install bash-completion

安装完成后

brew info bash-completion

提示

Add the following line to your ~/.bash_profile:

  [[ -r “/usr/local/etc/profile.d/bash_completion.sh” ]] && . “/usr/local/etc/profile.d/bash_completion.sh”

按要求把[[ -r “/usr/local/etc/profile.d/bash_completion.sh” ]] && . “/usr/local/etc/profile.d/bash_completion.sh”丢到.bash_profile里面

然后source ~/.bash_profile生效

2，安装git-completion

访问https://github.com/git/git/tree/master/contrib/completion

拷贝git-completion.bash文件内容(如果用的zsh就复制zsh的)，保存到~/.bash-completion.bash

然后 echo ‘source ~/.bash-completion.bash’ >> ～/.base_profile

source ～/.base_profile 生效

ok，使用git时，就能按tab自动补全命令了
