指定git路径，拉取远程所有的分支到本地，脚本

不知道为什么，感觉整理做过的事情真的是一件特别辛苦的事情，要从头撸一遍；

先贴一下脚本吧，后面再慢慢介绍调试过程，可以不看，我写给自己看的； 

#!/bin/bash#############################################################################使用环境：ubuntu 12.04英文版,只要是英文版 就行，因为一些字符串的判断是是以英文来的，试过ubuntu14.04的中文版不可以，因为命令提示是中文的#调试：s905x android6.0 SDK, s905 android 5.1 SDK,#功能说明：拉取指定路径的git的所有远程分支到本地#使用方法：#1. repo 新拉取的sdk,执行该脚本；#2. 已经在使用的sdk，可直接执行该脚本；不管当前git的状态如何，都处理为清除未提交内容，本地分支和远程分支不一致的使用远程分支；#3. 报错文件error_path，里面的路径需自行处理，处理方法为，删除问题目录，重新repo sync，然后再执行一次脚本即可；#4. 脚本多次执行没有问题#5. author: 罗云  qq:741790551################################################################################################################# 脚本使用方法: ./ly_repoladaima
