如何比较linux中的两个latex文件？

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，则得到输出。

例如：两个文件的 IP 地址都是 10.1.2.3。

New.tex

 \subsection {Summary of security vulnerabilities found on the host with IP address 10.1.2.3}
\begin{center}
\begin{longtable}{|p{0.2in}|p{0.5in}|p{4in}|p{0.4in}|} \hline
\textit{\textbf{No}} &\textit{\textbf{Severity level}} & \textit{\textbf{Vulnerability name}} & \textit{\textbf{More}} \\ \hline
     1  & \cellcolor{Red}High& DNS Server Cache Snooping Remote Information Disclosure  & \href{http://www.rootsecure.net/content/downloads/pdf/dns\_cache\_snooping.pdf}{$\Rightarrow$}  \\ \hline
     2  & \cellcolor{BurntOrange}Medium & SSL Certificate with Wrong Hostname  & \href{http://www.tenable.com/plugins/index.php?view=single&id=45411}{$\Rightarrow$}  \\ \hline

\end{longtable}
\end{center}

\end{longtable}
\end{center}

在这种情况下，

两者都有漏洞 ="DNS Server Cache Snooping Remote Information Disclosure" "SSL Certificate with Wrong Hostname" "SSL Self-Signed Certificate"

我需要输出

只有漏洞摘要如下

\subsection {Summary of security vulnerabilities found on the host with IP address 10.1.2.3}
\begin{center}
\begin{longtable}{|p{0.2in}|p{0.5in}|p{4in}|p{0.4in}|} \hline
\textit{\textbf{No}} &\textit{\textbf{Severity level}} & \textit{\textbf{Vulnerability name}} & \textit{\textbf{More}} \\ \hline

如何在 linux 上使用 bash 脚本、awk、sed 或任何其他方法实现此目的？

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，您可以在其中读取两个文件，找到您感兴趣的行，比较它们，然后进行所需的替换。

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 定位该行并添加-A8 以同时捕获接下来的 8 行上下文。在您的情况下，可能会执行以下操作：

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

假设单词组合对于漏洞行是唯一的，那么您将获得上面您指出的行。
