不确定这是不好的风格,但我在这里问这个问题,因为我在其他地方找不到答案,然后我自己制定了一个解决方案.我有兴趣看到其他人的解决方案,但过了几天我会发布自己的解决方案.
在我的具体情况下,我在Windows 7上运行,但我对其他/旧版Windows的答案感兴趣.我意识到一个答案是“安装一个版本的Unix查找,然后是solve as for Unix”,但我想要一个更“本机”的解决方案.
编辑2012-07-17：澄清：通过“自动”我理想地意味着我可以作为脚本的一部分运行,而不是一个GUI工具,按下按钮完成所有工作,因为我想要做这无人看管.
有些迟了,但这是我对自己问题的回答.它与Unix上通常使用的方法基本相同：找到所有链接,然后根据破坏的链接进行操作;它不是那么简洁.在转出有关它们的一些信息后,下面的脚本会删除损坏的符号链接.
