git自动补全

1.安装git配套脚本完全版

brew install bash-completion

安装完成后会有一段提示：

Add the following lines to your ~/.bash_profile:

if [ -f $(brew --prefix)/etc/bash_completion ]; then

. $(brew --prefix)/etc/bash_completion

fi

2.将if...then之间的语句添加到bash_profile中

3.下载git源码，获取git-completion.bash文件，路径：contrib/completion/git-completion.bash

git clone https://github.com/git/git.git

4.复制到根目录并改名为.git-completion.bash

cp git-completion.bash ~/.git-completion.bash

5.添加下面语句到~/.bash_profile

source ~/.git-completion.bash

重启shell终端，ok！
