// 获得CPU ID

dmidecode -t 4 | grep ID |sort -u |awk -F': ' '{print $2}'

// 获得磁盘ID

fdisk -l |grep "Disk identifier" |awk {'print $3'}

查看CPU信息

cat /proc/cpuinfo

显示当前硬件信息

sudo lshw

获取CPU序列号或者主板序列号

#CPU ID

sudo dmidecode -t 4 | grep ID

#Serial Number

sudo dmidecode  | grep  Serial

#CPU

sudo dmidecode -t 4

#BIOS

sudo dmidecode -t 0

#主板：

sudo dmidecode -t 2

#OEM:

sudo dmidecode -t 11

显示当前内存大小

free -m |grep "Mem" | awk '{print $2}'

查看硬盘温度

sudo apt-get install hddtemp

sudo hddtemp /dev/sda
