Android系统代码本地更新Linux shell脚本2

Android系统代码本地更新Linux shell脚本2相当于Android系统代码本地更新（Linux系统）原理差不多、修改和使用方法更简单。可以带参数（脚本运行方法：./sync.sh Remote_repository_name Remote_Public_source Original_source Public_source Your_branch ），也可以到脚本中修改默认一些变量（RRN（Remote repository name） RPS（Remote public source） OS（Original source） PS（Public source） YB（Your branch））。脚本如下：sync.sh
