How to check my hardware information in Linux?

Jun 29, 2025 am 12:34 AM

To view hardware information in Linux systems, you can use the following tools: 1. Use lscpu or /proc/cpuinfo to check CPU details; 2. Get memory information through free or vmstat; 3. Use lshw to get a complete hardware overview; 4. Use lsblk and df to view disk and storage information. Specifically, lscpu displays architecture, core count and threads, etc. /proc/cpuinfo provides underlying details such as virtualization support; free -h displays easy-to-read memory usage, vmstat -s provides advanced memory statistics; installing and running lshw can list all hardware components, and can generate easy-to-read formats through -short or -html; lsblk displays block devices, df -h view file system space usage, so as to fully grasp the system hardware configuration.

How to check my hardware information in Linux?

If you're using Linux and want to know what hardware is in your system, there are several straightforward tools that can give you detailed information. Whether you're troubleshooting, upgrading, or just curious, knowing how to check your hardware info is a useful skill.

How to check my hardware information in Linux?

Check CPU Info with lscpu or /proc/cpuinfo

One of the easiest ways to see your CPU details is by using the lscpu command. Open a terminal and type:

How to check my hardware information in Linux?
 lscpu

It shows you the architecture, number of cores, threads, model name, and more — all in a clean layout.

Alternatively, you can look directly at /proc/cpuinfo , which gives a bit more low-level detail:

How to check my hardware information in Linux?
 cat /proc/cpuinfo

This includes per-core information, cache sizes, and CPU flags. It's especially helpful if you're checking for specific features like virtualization support ( vmx for Intel or svm for AMD).

Get Memory (RAM) Details via free or vmstat

To check how much RAM your system has and how it's being used, the free command is quick and simple:

 free -h

The -h flag makes the output human-readable, showing memory in GB or MB as appropriate.

For more advanced memory stats, including swap usage and page activity, try:

 vmstat -s

These tools help you understand not just total RAM, but also how much is free, cached, or used by applications.

Use lshw for a Full Hardware Overview

If you want a comprehensive list of all major hardware components — from CPU and RAM to network cards and storage — lshw is your go-to tool.

Install it if it's not already available:

 sudo apt install lshw # On Debian/Ubuntu

Then run:

 sudo lshw

You can make the output easier to read by adding -short :

 sudo lshw -short

Or generate an HTML report by using:

  • sudo lshw -html > hardware.html
    Then open the file in a browser for a nicely formatted view.

This is especially handy when documenting a machine's specs or preparing for hardware upgrades.

See Disk and Storage Info with lsblk and df

To get a clear picture of your storage setup, lsblk shows all block devices — hard drives, SSDs, and partitions:

 lsblk

If you want to see disk space usage on mounted filesystems, use df :

 df -h

This helps identify how much space is used or left on each drive. For even more detail, including disk model and health status, smartctl (from the smartmontools package) is worth installing.


That's most of what you need to know about checking hardware in Linux — these commands cover the essentials without needing any third-party software.

How to troubleshoot DNS issues on a Linux machine? How to troubleshoot DNS issues on a Linux machine? Jul 07, 2025 am 12:35 AM

When encountering DNS problems, first check the /etc/resolv.conf file to see if the correct nameserver is configured; secondly, you can manually add public DNS such as 8.8.8.8 for testing; then use nslookup and dig commands to verify whether DNS resolution is normal. If these tools are not installed, you can first install the dnsutils or bind-utils package; then check the systemd-resolved service status and configuration file /etc/systemd/resolved.conf, and set DNS and FallbackDNS as needed and restart the service; finally check the network interface status and firewall rules, confirm that port 53 is not

In Linux systems, 1. Use ipa or hostname-I command to view private IP; 2. Use curlifconfig.me or curlipinfo.io/ip to obtain public IP; 3. The desktop version can view private IP through system settings, and the browser can access specific websites to view public IP; 4. Common commands can be set as aliases for quick call. These methods are simple and practical, suitable for IP viewing needs in different scenarios.
