This article describes, under Linux to view the hardware information commands and methods, including the motherboard serial number, CPU information, memory information, hard disk information, network card information.
1, motherboard information. View the motherboard serial number
#使用命令
Dmidecode | Grep-i ' Serial number '
#查看板卡信息
Cat/proc/pci
2,CPU Information
#通过/proc File system
1) Cat/proc/cpuinfo
#通过查看开机信息
2) DMESG | Grep-i ' CPU '

2) DMESG | grep mem
3) free-m
4) Vmstat
5) Dmidecode | Grep-i Mem
5, network card information
1) DMESG | Grep-i ' ETH '
2) cat/etc/sysconfig/hwconf | Grep-i ETH
3) Lspci | Grep-i ' ETH '
6, mouse keyboard and USB information
View keyboard and mouse: Cat/proc/bus/input/devices
Viewing USB devices: Cat/proc/bus/usb/devices
To view interrupt requests (IRQ) for each device: cat/proc/interrupts
7, Graphics information
1) lspci |grep-i ' VGA '
2) DMESG | Grep-i ' VGA '
8, sound card information
1) lspci |grep-i ' VGA '
2) DMESG | Grep-i ' VGA '
9, other orders
Detection of new hardware using hardware detection program Kuduz: Service kudzu start (or restart)
. DMESG (View all hardware information that was detected at startup)
. LSPCI (Display peripheral information, such as USB, NIC, etc.)
. cat/etc/sysconfig/hwconf
. mpstat
10, need to manually install the tool
Lshw,hwinfo,hal-device-manager
