Ubuntu下察看电脑的硬件规格

命令：  sudo dmidecode

会分门别类地举出系统各个部分的所有信息。

如果想看某一项，可以用

sudo dmidecode -t processor      (CPU核芯)

sudo dmidecode -t memory        (内存)

sudo dmidecode -t cache             (缓存)

sudo dmidecode -t system           (电脑型号、产商)

sudo dmidecode -t slot                 (插卡槽)

sudo dmidecode -t baseboard     (主板)

sudo dmidecode -t connector      (连接设备)

sudo dmidecode -t chassis           (机箱)

sudo dmidecode -t bios                 (BIOS)  

或者用数字表示，例如，查看内存的具体型号，可以用：  sudo dmidecode -t 17
