mac git命令参数tab键补全

1. 安装bash-completion

$ brew install bash-completion
$ brew tap homebrew/completions

2. 在用户目录.bash_profile添加如下脚本

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

3. 增加git命令补全

$ cd /usr/local/opt/bash-completion/etc/bash_completion.d
$ curl -L -O https://raw.github.com/git/git/master/contrib/completion/git-completion.bash
$ brew unlink bash-completion
$ brew link bash-completion

4. 以上步骤做完，即可实现git命令参数补全功能

$ git chec          # 按tab键补全参数

$ git checkout dev  #假如有分支名为dev-master，tab键之后会自动补全分支名
