This article introduces the relevant knowledge of "the method of Linux viewing hardware information". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
1. Lshw
The lshw command displays detailed hardware information. If you want to display it in summary mode, you can add the short parameter: lshw-short
To display the specified hardware information, add the class (or C) parameter: lshw-class memory
2. Sysstat
3. Check out the PCI information: lspci-v (more intuitive than cat / proc/pci). Lspci reads the hwdata database, and hwdata is provided by the software package hwdata.
4. View the system architecture: uname-a
5. Dmidecode views hardware information, including bios, cpu, memory, etc.
6. Dmesg is a tool for displaying kernel buffer system control information; for example, the system information at startup is written to / var/log/.
Note: the dmesg tool is not specifically used to view the hardware chipset identification, but through this tool we can know some parameters of the hardware in the machine, because the system will write some hardware-related logs to the / var/log/message* or / var/log/boot* file when booting.
7. Lshal and hal-device-manager
8. View / proc
Files in "/ proc" can be browsed using the file view command, which contains system-specific information:
Cpuinfo host CPU information
Dma host DMA tunnel information
Filesystems file system information
Interrupts host interrupt information
Ioprots host IZP O port number information
Meninfo host memory information
Version Linux memory version information
View CPU information: cat / proc/cpuinfo
View board information: cat / proc/pci
View memory information: cat / proc/meminfo
View USB devices: cat / proc/bus/usb/devices
View keyboard and mouse: cat / proc/bus/input/devices
View interrupt requests (IRQ) for each device: cat / proc/interrupts
