Use of Centos command to View hardware information

In windows, we can easily obtain computer hardware information. in Linux, what commands can be used to obtain system hardware information, the following describes the Linux hardware information commands: 1. check the serial number of the motherboard ---------------------------------------------- # use the command dmidecode | grep-I & #39

In windows, we can easily obtain computer hardware information. in Linux, what commands can be used to obtain system hardware information, the following describes Linux hardware information commands:

1. motherboard information　

View the serial number of the motherboard
--------------------------------------------------
# Use commands
Dmidecode | grep-I 'serial number'
# View board information
Cat/proc/pci
--------------------------------------------------

2. cpu information

--------------------------------------------------
# Use the/proc file system
1) cat/proc/cpuinfo
# View The Boot Information
2) dmesg | grep-I 'CPU'
#
3) dmidecode-t processor
--------------------------------------------------

3. hard disk information

--------------------------------------------------
# View partition information
Fdisk-l
# View the size
Df-h
# View usage
Du-h
#
Hdparm-I/dev/sda
#
Dmesg | grep sda
--------------------------------------------------

4. memory information

--------------------------------------------------
1) cat/proc/meminfo
2) dmesg | grep mem
3) free-m
4) vmstat
5) dmidecode | grep-I mem
--------------------------------------------------

5. Nic 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 the keyboard and mouse: cat/proc/bus/input/devices
View USB devices: cat/proc/bus/usb/devices
View interrupt requests of each device (IRQ): cat/proc/interrupts

7. video card information

--------------------------------------------------

--------------------------------------------------

8. sound card information

--------------------------------------------------
1) lspci | grep-I 'vga'
2) dmesg | grep-I 'vga'
--------------------------------------------------

7. Other Linux hardware information commands

Use the hardware detection program kuduz to detect the new hardware: service kudzu start (or restart)
. Dmesg (view all hardware information detected at startup)
. Lspci (display peripheral information, such as usb and NIC)
. Cat/etc/sysconfig/hwconf
. Mpstat

8. tools to be manually installed

Lshw, hwinfo, hal-device-manager

The above are some Linux hardware information commands that can view the hardware information of machines under characters.
