【Git】把git的分支号加到linux终端前

把下面的代码加入到 ~/.bashrc的文件最后

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='\[\e[37;40m\][\[\033[01;36m\]\u\[\e[37;40m\]@\[\e[0m\]\h \[\033[01;36m\]\W\[\033[01;32m\]$(git_branch)\[\033[00m\]\[\e[37;40m\]]\[\e[0m\]\$ '

然后source ~/.bashrc就可以了
