Question

我需要将New.tex http://pastebin.com/PCafGYwG与Old.tex http://pastebin.com/jRU8rhhV进行比较，如果同一IP中的两个文档中存在相同的漏洞，则需要输出。

例如：两个文件的IP地址为10.1.2.3。

New.tex

在那种情况下，

都有漏洞=“DNS服务器缓存侦听远程信息泄露”“具有错误主机名的SSL证书”“SSL自签名证书”

我需要输出

仅漏洞摘要如下

如何使用bash脚本，awk，sed或任何其他方法在linux上实现此目的？

Answer 1

您可以使用diff命令或diffuse GUI工具比较两个文件：

diff Old.tex New.tex

或

diffuse Old.tex New.tex

要进行更深入的分析，我建议您编写一个简短的python（或perl）脚本，在这里您可以读取这两个文件，找到您感兴趣的行，进行比较，并进行必要的替换。

Answer 2

最简单的方法是在第一行中找到要搜索的唯一文本，然后使用grep找到该行并添加-A8以捕获接下来的8行上下文。在您的情况下，可能会出现以下情况：

grep -A8 {Summary\ of\ security\ vulnerabilities filename

假设单词组合对于漏洞行是唯一的，那么您将得到您指出的上述行。
