ssh终端显示git分支

切换到自己的home文件夹下面，

vim .bashrc 
//将以下代码加入到文件中去
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)\[\033[00m\] \$ '

//然后刷新一下
source .bashrc
