Linux hardware configuration revealed, do you really understand it?

Understanding and mastering hardware configuration is crucial for daily use of Linux operating systems. Because different hardware choices will directly affect the performance and stability of the system. Therefore, you need to learn to accurately detect and compare hardware combinations. The following shows you in detail how to view hardware information under a Linux system and evaluates and compares various common industry practices.

1. lshw command

I would like to recommend this excellent tool LSHW to everyoneHow to check the hardware configuration of the Linux system, it can display all the characteristics of the computer hardware in detail, such as the CPU, memory, hard disk and network card mentioned above etc. are included. You may wish to try this small command in the terminal!

```

sudo lshw -short

You can display brief information about all hardware devices in the system.

2. dmidecode command

Want to know the computer hardware configuration? We have prepared a useful little tool called dmidecode for you. Just run this command to easily get detailed information about core components such as the motherboard, BIOS, and memory. For example, the following command format can be used with slight adjustments:

sudo dmidecode

can display detailed hardware information on all aspects of the system.

3. lscpu command

Dear friends, as we all know, you can use the lscpu command to quickly view the detailed information of the processor (i.e. CPU), including its model, number of cores, number of threads, and even cache capacity. By simply operating this command, you can quickly understand and optimize the performance of your system's CPU. It's duplicity, just like entering the following prompt:

lscpu

will display the detailed information of the CPU in the system.

4. lsusb command

Use the lsusb commandHow to check the hardware configuration in Linux system, you can easily obtain the detailed information of the USB device! It can help you view various related parameters of connected USB devices in the system, such as manufacturer ID, product ID, etc. For example, just enter the following simple command:

lsusb

will display information about the USB devices connected to the system.

5. lspci command

"lspci" is really a powerful assistant for revealing PCI device information in detail! Simply enter this command to quickly learn all the PCI devices included in your system, their detailed classification and manufacturer identification numbers. For example, you can do this:

lspci

You can display information about the PCI devices installed in the system.

6. hwinfo command

hwinfo is a powerful and easy-to-use hardware diagnostic tool. It can help you easily obtain various hardware configuration information, including detailed information on core elements such as processors, memory, hard disks, and network interfaces. For example, to query processor information, you only need to enter the following command to get the result immediately:

sudo hwinfo --short

7./proc file system

Dear readers, please allow me to briefly introduce to you a unique setting in the Linux system-/proc file system. This is a collection of virtual files that stores a large amount of system status and hardware information. You can easily browse and gain insights into the details of multiple areas such as CPU, memory, and hard disk. Taking the instance as an example, you can complete the query action through the following corresponding instructions:

cat /proc/cpuinfo

Can display detailed information of the CPU.

8. GUI Tools

In addition to the command line tools and the linux command tar, we also have many simple and visual graphical interface tools to help you explore hardware configuration information in depth. For example, you can easily check the detailed information of each hardware device by tapping the "Details" tab in the GNOME system settings! In addition, for 64-bit Linux, some third-party applications such as HardInfo and lshw-gtk can also assist you in system checking of hardware configuration in an intuitive and clear way ~ It is really convenient!
