我有以下代码，使用 stings 命令提取。

我需要编辑代码并编译。但我不知道如何继续。

此外，我不知道上面的代码试图做什么。

如果有人能够这样做会非常有帮助：

解释代码。
如何反编译
如何在更改后编译。

谢谢，阿尼什

我有以下代码，使用stings命令提取我需要编辑代码并编译。

你的第一步应该是：找一个有线索的人。您不可能实现自己想做的任何事情。

那就是说，strings 不提取代码，它只从代码中提取可打印的字符串。因此，有没有代码来解释。（如果您要了解任何内容，还应阅读man strings。）

假设您仍然拥有原始二进制文件，而不仅仅是strings输出，则可以使用objdump -d（执行读取man objdump来反汇编该二进制文件）。那个输出，如果它足够小，你可以希望有人能够理解并向你解释（你也可以尝试自己理解它，配备SPARC装配手册，如作为this one）。

一旦你理解了程序的功能，就可以在C中编写一个等效的程序，最后修改它以做任何你想做的事情。但是从头开始编写这样的程序可能更简单，而不是通过反编译/修改路由。
