使用lshw读取硬件信息

lshw是一个读取硬件信息的命令行工具。

安装lshw

archlinux默认并没有安装 lshw,你需要手工安装

sudo pacman -S lshw

使用lshw

注意: 由于lshw需要读取硬件信息,因此需要使用root权限

列出硬件信息

直接运行lshw就能列出本机上的硬件信息了:

sudo lshw

结果为:

若你觉得输出很乱,其实 lshw 也提供了一个GUI界面给你使用。

lshw -X

让lshw现实SCSI,USB,IDE和PCI设备的信息

通过 -businfo 可以获取主线信息

sudo lshw -businfo

结果为:

这样就很容易用 jq 之类的信息从中抽取信息了。

让lshw显示出敏感信息

默认情况下,lshw会隐藏IP地址、serial number之类的敏感信息,若你希望把这类信息也显示出来,则可以执行

sudo lshw -sanitize

获取帮助

lshw -help

会在stderr中显示简单的参数说明:

Hardware Lister (lshw) - unknown
usage: lshw [-format] [-options ...]
       lshw -version

        -version        print program version (unknown)

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

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.)
        -notime         exclude volatile attributes (timestamps) from output
