1.输入 dmidecode -t 列出关键字

dmidecode: option requires an argument – ‘t’
Type number or keyword expected
Valid type keywords are:

bios
system
baseboard
chassis
processor
memory
cache
connector
slot

然后在 dmidecode -t system 或 dmidecode -t 1 输出

# dmidecode 3.1
Getting SMBIOS data from sysfs.
SMBIOS 2.7 present.

Handle 0x0001, DMI type 1, 27 bytes
System Information

Product Name: 33661R8
Version: ThinkPad Edge E530c
Serial Number: MP43X9V
……

2.dmidecode -s

dmidecode: option requires an argument – ‘s’
String keyword expected
Valid string keywords are:
bios-vendor
bios-version
bios-release-date
system-manufacturer
system-product-name
system-version
system-serial-number
system-uuid
baseboard-manufacturer
baseboard-product-name
baseboard-version
baseboard-serial-number
baseboard-asset-tag
chassis-manufacturer
chassis-type
chassis-version
chassis-serial-number
chassis-asset-tag
processor-family
processor-manufacturer
processor-version
processor-frequency

dmidecode -s system-version 输出

lshw(Hardware Lister)

安装:apt-get install lshw
lshw 比较简单 lshw –help

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

1.把信息保存为HTML/XML格式文本

lshw -html > my.html
lshw -xml > my.html

2.显示设备列表，输出包括设备路径(path)、类别(class)以及简单描述 lshw -short

H/W path Device Class Description
……

3.显示指定类别的设备 lshw -C xxxx,其中 xxxx 就是 lshw -short 中的 Class 字段.如 lshw -C disk

*-disk
description: ATA Disk
product: WDC WD5000LPVT-0
vendor: Western Digital
……
*-cdrom
……

例如: lshw -C system|grep version 输出

version: ThinkPad Edge E530c
