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:
