二进制文件分析工具-hexdump使用指南

一 概念:

hexdump是Linux下的一个二进制文件查看工具，它可以将二进制文件转换为ASCII、八进制、十进制、十六进制

格式进行 查看。

二 用法简介:

   该工具的用法十分简单，具体如下所示:

hexdump: 不适用的选项 -- -
usage: hexdump [-bcCdovx] [-e fmt] [-f fmt_file] [-n length]
               [-s skip] [file ...]
       hd      [-bcdovx]  [-e fmt] [-f fmt_file] [-n length]
               [-s skip] [file ...]

三 应用实例：

  该工具用法十分简单，下面以一个c代码例子来说明:

#include <stdio.h>

int main()
{
        printf("hello hexdump");
}
~            

   通过这个查看该bin文件的编译信息:
