【问题描述】：
我有两个文件，其中包含有关 IP 地址的一些信息。我需要比较这些文件，然后我需要创建一个新文件，其中只包含 New.txt 和 Old.txt 共有的项目。我需要将它作为批处理运行，这就是为什么我需要知道 unix 命令来自动化这个过程。
尽管如此，重要的事实是，虽然两个文件中的描述可能相同，但起始编号可能不同。
例如： 新建.txt

【问题讨论】：
-
1.如果结果必须包含两个文件中具有相同 IP 地址的项目，为什么还要在 compare.txt 中包含甚至没有 IP 的前 4 行和后 2 行地址？2.你想要结果中的 Old.txt 文件的完整行吗？只包含 IP 地址不是更好吗？3.“批处理文件”标签是指 Windows .BATch 文件（您可以查看标签说明）。如果您想要的不是 .BAT 文件解决方案，而是 Unix 解决方案，请删除此标签；否则请确认您需要一个 Windows .BAT 文件（并删除“unix”标签）。
