linux下获取CPUID,MAC地址,硬盘序列号,主板序列号

以下代码的思想都参考了他人的思想,因为参考的人的博客比较多,我也不记得是哪些了,故此就不列出了

但是代码都是本人亲自编写的,并通过测试,现在分享代码,希望可以方便自己和他人

方便测试的Makefile:

build :
	g++ -o get_cpu_id get_cpu_id.cpp
	g++ -o get_mac_address get_mac_address.cpp
	g++ -o get_disk_serial_number get_disk_serial_number.cpp
	g++ -o get_board_serial_number get_board_serial_number.cpp

run   :
	@echo "--------------------"
	@- ./get_cpu_id
	@echo "--------------------"
	@- ./get_mac_address
	@echo "--------------------"
	@- ./get_disk_serial_number
	@echo "--------------------"
	@- ./get_board_serial_number
	@echo "--------------------"

clean : 
	-rm get_cpu_id
	-rm get_mac_address
	-rm get_disk_serial_number
	-rm get_board_serial_number

rebuild : clean build


编译:make 或者 make build

运行:make run 或者 sudo make run (上面大多数信息都需要超级用户权限才能获取到结果)

清理:make clean (这个写得太死了,本来是想删除非cpp文件的,shell写不出来)

重编:make rebuild
