在vbscript中调用plink.exe 遇到问题，请各位大神帮忙看看如何解决

[baidu_29126565]

本人最近自己写了个小工具用来自动登录linux/unix服务器下载文件，ssh登录我使用的是putty下面的命令行工具plink，但是有个问题，plink首次登录时会提示rsa2，提示要不要保存，保存输入“y”，之后才能继续，如下图：


我现在要实现的是这么个功能，登录之后判断返回是否包含这个提示语句，如果包含则输入一个y加回车，如果不包含则继续其他的工作，这段代码要怎么实现呢？

没有写过vb，很老的语言了，bug很多，都不用 了

逆向plink.exe，跳过该提示。

额 我只是写个小工具 没必要搞这么大阵仗吧 有没有简单一点的办法呢
