Dmidecode

Dmidecode 可以读取硬件信息, 直接输入 sudo dmidecode 会输出大量信息, 可以按照下面的表格分类显示

# 显示BIOS信息
sudo dmidecode -t 0

lshw

lshw(Hardware Lister)是另外一个可以查看硬件信息的工具, 不仅如此, 它还可以用来做一些硬件的benchmark. 这个工具其实就是用/proc里面读取一些文件来显示相关的信息, 它用到了如下文件和目录:

显示帮助

ubuntu@ubuntu:~$ sudo lshw -h
Hardware Lister (lshw) - B.02.16
usage: lshw [-format] [-options ...]
       lshw -version

    -version        print program version (B.02.16)

format can be
    -html           output hardware tree as HTML
    -xml            output hardware tree as XML
    -short          output hardware paths
    -businfo        output bus information

options can be
    -class CLASS    only show a certain class of hardware
    -C CLASS        same as '-class CLASS'
    -c CLASS        same as '-class CLASS'
    -disable TEST   disable a test (like pci, isapnp, cpuid, etc. )
    -enable TEST    enable a test (like pci, isapnp, cpuid, etc. )
    -quiet          don't display status
    -sanitize       sanitize output (remove sensitive information like serial numbers, etc.)
    -numeric        output numeric IDs (for PCI, USB, etc.)
