unix学习过程中找不到ourhdr.h文件
首先我先来介绍一下什么是ourder.h文件，这就是作者自己写的一个库，比如unix或Linux中unistd.h这就是系统自己的函数库，这些库函数都在/usr/include中，所以我们要想编译含有ourhdr.h的c文件，必须手动导入库
以下是ourhdr.h的库文件：
/Our own header, to be included after all standard system headers/
#ifndef __ourhdr_h
#define __ourhdr_h
#include <errno.h>/*for definition of errno */
#include <stdarg.h>/ANSI C header file/

#include <stdio.h> / for convenience /
#include <stdlib.h> / for convenience /
#include <string.h> / for convenience /
#include <unistd.h> / for convenience /

将这个文件复制放在/usr/include下

为什么要在这里用sudo那？
因为我试过如果直接vi 然后保存，是会出现无法打开并写入文件的报错
鉴于新手我顺带讲一下windows和ubuntu的之间复制粘贴问题：
以下完美解决：
sudo apt-get autorremove open-vm-tools
sudo apt-get install open-vm-tools
sudo apt-get install open-vm-tools-desktop
重启虚拟机
这样直接就可以右键在vim文件中弹出来粘贴

解决完复制粘贴问题，你就把之前提到的ourhdr.h复制到/usr/include下
其实到这一步解决了80%问题
因为unix那本书里面还有err_sys这个函数，其实这个函数也是作者写的my_err.h头文件中的函数，你要是真想把书上的运行起来，你就在网上找然后继续复制粘贴到/usr/include下
反正我试过一次，没成功，因为太懒了，感觉那个err_sys就实现输出，还不如用printf，反正运行成功了最后
