这代码怎么把业务结合起来？所以，也不是可以拿来用的代码

一个显示复制进度的shell（进度条按复制比例显示） 2010年12月31日 19:09:34 weixin_34368949 阅读数 21 原文链接：http://blog.51cto.com/newyorks/470063

这个脚本有个小bug，在复制文件数目小于100的文件夹时可以正常显示，超过100时就不正常显示。另外，不知道如何才会出现小数，请指点。转载于:https://blog.51cto.com/newyorks/470063

### 进度条打印方法 progress_bar
### 在每个过程方法中，通过两个全局变量PROGRESS_FUNC_BEGIN和PROGRESS_FUNC_END
### 控制进度条显示的progress数字进度，把progress作为$1传到progress_bar
### progress_bar的$2为显示的提示信息
