读取硬件的 ID

当需要读取硬件的 ID 来作为认证用。可以使用以下指令。

cpu id

dmidecode -t processor  | grep "ID" | cut -d ":" -f 2

memory id

dmidecode -t memory  | grep "Serial Number"  | cut -d ":" -f 2 | grep -w "[0-9a-fA-F]\+"		# <-- 会有多个返回

os id

dmidecode -t system  | grep "UUID"  | cut -d ":" -f 2

harddisk id

fdisk -l | grep "Disk identifier" | cut -d ":" -f 2				# <-- 会有多个返回

ehter card mac address

ifconfig -a | grep ether  | cut -d " " -f 10					# <-- 会有多个返回
