Mac Git配置

在使用Mac进行编码过程中，为了适应自己的使用习惯，针对Git 进行一些优化配置，主要配置如下：

1. git 自动补全

    1）curl https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash -o ~/.git-completion.bash

    2）vi ~/.bash_profile

    3）if [ -f ~/.git-completion.bash ]; then. ~/.git-completion.bashfi

    4）source ~/.bash_profile

2. git显示当前分支

    1）vi .bashrc

    2) function git_branch {

      branch="`git branch 2>/dev/null | grep "^\*" | sed -e "s/^\*\ //"`"

      if [ "${branch}" != "" ];then

          if [ "${branch}" = "(no branch)" ];then

              branch="(`git rev-parse --short HEAD`...)"

          fi

          echo " ($branch)"

      fi

    }

    export PS1='\u@\h \[\033[01;36m\]\W\[\033[01;32m\]$(git_branch)\[\033[00m\] \$ '

    3) source ./.bashrc
