Linux display system information

How to Display System Details and Hardware Information on Linux

A master craftsman is deeply familiar with the tools he or she works with, and you need to be familiar with your Linux system and the hardware it runs on if you want to call yourself an advanced user.

Knowing how to display system details and hardware information on Linux is guaranteed to come in handy when troubleshooting all kinds of problems, from hardware devices not showing up to software applications not installing or running correctly.

As is usually the case, Linux gives you multiple ways to display system details and hardware information, some requiring more technical knowledge than others.

Method 1: CPU-X

If you’re familiar with CPU-Z, a freeware system profiling and monitoring application for Microsoft Windows, then you’ll love CPU-X, its free and open-source alternative.

CPU-X runs on Linux and FreeBSD, and it has a graphical user interface designed after the application that inspired it. There’s also a text-based user interface created using the ncurses library, plus a special dump mode that’s useful for outputting all collected information into a text file.

You can download CPU-X from the official repositories of most major Linux distributions, including Ubuntu, Fedora, and Solos, or you can build it yourself following the step-by-step guide on the Wiki.

Method 2: Hardware Lister (lshw)

Hardware Lister is a tool for gathering detailed hardware information. The tool comes with an optional graphical user interface that displays the gathered information in a more user-friendly manner, but most users rely only on the lshw command.

If you’re using a major Linux distribution like Ubuntu, the lshw command (but not the GUI, called lshw-gui) will likely already be installed on your system. To use it, all you need to do is enter the following command in the terminal:

Hardware Lister will then display a long list of information about your Linux machine, including its name, CPU, connected USB devices, memory, and more.

Method 3: Neofetch

This command-line system information tool written in bash is loved by aesthetically-oriented Linux users for its ability to display basic OS, software, and hardware information in a visually pleasing manner. To use Neofetch with its default settings, simply install the tool and invoke it in your favorite terminal emulator:

By default, Neofetch will display your operating system’s logo on the left (more than 150 operating systems are supported) and system information on the right. You can also configure Neofetch to use an image, a custom ASCII file, the current wallpaper, or nothing at all.

Method 4: inxi

inxi (never capitalized) is a command line system information tool that started as infobash, developed by locsmif.

“That was a buggy, impossible to update or maintain piece of software, so the fork fixed those core issues, and made it flexible enough to expand the utility of the original ideas,” explains the project’s GitHub page.

So, what can inxi tell you about your system and the hardware it runs on? Just about anything you could possibly need for basic troubleshooting and more.

To tell inxi to display full output with extra details, use the following command:

If you want to share the collected information with strangers on the internet, you can also include the -z flag, which masks out personally identifying information like your MAC and IP address.

Method #5: ls* Commands

To display system details and hardware information on Linux, you actually don’t need to download any third-party software. Instead, you can take advantage of the so-called ls* commands to display information gathered from places like /proc.

Here are the ls* commands you should know about:

  • lscpu: used to display information about the CPU.
  • lsusb: used to display information about USB buses in the system and the devices connected to them.
  • lspci: used to display information about PCI buses and devices in the system.
  • lssci: used to display information about scsi/sata devices.

Each of these commands supports a variety of flags, so we recommend you study their man pages to for more information about them.

Summary

In this article, we’ve described five ways to display system details and hardware information on Linux to help you quickly collect the information you need to troubleshoot any problem. Now, it’s up to you to pick the method you like the most and put it to good use.

Get Linux System and Hardware Details on the Command Line

Sysinfo Linux - Get Linux System Information

Get Linux System Information

If you are using Linux, you may need to know details about the system or the hardware specifications you are using. As a regular Linux user or software developer, it is important that you check the compatibility of any software or hardware system that you want to install. The Linux command line contains several built-in commands that help you become familiar with the software and hardware platform you are working on. This tutorial will teach you how to use these commands to get the sysinfo Linux details.

The commands and examples to get hardware specs from Linux in this tutorial have been tested on Ubuntu 22.04 and Debian 11.

Displaying Basic System Information on Linux Shell

To know the basic information about your system, you need to be familiar with the command-line utility called uname-short for unix name.

The uname Command

The uname command comes with multiple switches. The basic command as described below only returns the Kernel name:

Result of uname command

As you can see, the uname command when used without any switches only returns the kernel name i.e., Linux for my system.

Get the Linux Kernel Name

When you precisely want the command to print the kernel name, you will use the following command:

Kernel name displayed with uname command

The above output has displayed Linux as my kernel name.

Get the Linux Kernel Release

In order to print the release information of your kernel, use the following command:

Get Linux Kernel release information

The above command has displayed the release number of my Linux

Get the Linux Kernel Version

To fetch the version of your kernel, use the following command:

Linux Kernel version

The above output shows the version number of my kernel.

Get Network Node Hostname

You can use the following command to print the network hostname of your node:

You can also use the following command for the same purpose as it is more user-friendly:

Get system hostname

Both commands will display the same output. Please note that the host and node names might not be the same for non-Linux systems.

Get Machine Hardware Architecture (i386, x86_64, sysinfo Linux)

In order to know the hardware architecture of the system you are working on, please use the following command:

Get Linux architecture x86_64

The output x86_64 signifies that I am using a 64-bit architecture. The output i686 means that a user is on a 32-bit system.
