A detailed introduction to the use of 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

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 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

10. 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.
