On the other hand, with Linux system info at your disposal, you will always be ready to perform system maintenance and troubleshooting effectively.
How to Use Commands to Get Linux System Info
Various commands are available in Linux to retrieve detailed information about the system. To learn the configuration of your system, hardware, and software, each command gives you a certain set of data. So let’s discuss a few of the most useful commands to find system info Linux:
Linux System Info Command: uname
The uname command is one of the oldest yet still informative commands on Linux system info. The output gives information about your kernel, system architecture, device, and more.

the latest updates directly in your inbox.
Usage:
uname -aThis command gives you detailed system information, such as:
- Kernel name (Linux)
- Kernel version
- Hostname
- System architecture (e.g., x86_64)
- Processor type (e.g., Intel)
- Operating system
How to Get Linux System Information with lsb_release
The lsb_release command shows release-specific details about the Linux distribution running on your system, including its version, codename, and release number. This is particularly useful if you’re not certain which distribution of Linux is installed.
Usage:
lsb_release -aYou will see the output of this command:
- Distributor ID (Ubuntu, Debian, etc.)
- Description (for example, Ubuntu 22.04 LTS)
- Release (e.g., 22.04)
- Codename (e.g., Jammy)
Using cat /etc/os-release
The cat /etc/os-release command is another easy method used to get Linux system info about your distribution. You will get detailed information about the OS read from the OS release file — the OS name, version, etc.
Usage:
cat /etc/os-releaseThe output will include:
- Operating System (OS) Name (e.g. Ubuntu, Fedora)
- Whatever OS version (e.g., 20.04 LTS)
- The ID (e.g., ubuntu)
- Build details
Check CPU Info with lscpu
Command to show your CPU architecture and performance: lscpu It shows information like the number of CPU cores, threads, architecture, model, etc.
Usage:
lscpuThe output includes:
- CPU architecture (e.g. x86_64)
- CPU Cores and Threads Count
- CPU model
- CPU speed
- Flags and features available on the CPU (virtualization support, etc.)
Use free for Memory Info
The free command displays statistics about memory usage for both RAM and swap memory. It is especially helpful to keep an eye on system performance and make sure that your machine is not running out of memory.
free -hThe argument -h makes the output human-friendly display memory in either megabytes (MB) or gigabytes (GB). The output will show:
- Total memory (RAM)
- Used and free memory
- Swap space (used/free)
Use lsblk To List Detailed Disk Information
The lsblk command is great for disk-related Linux system info. It can also provide information on all available block devices (even if they are not yet mounted) such as hard drives or SSDs with detailed information like size, type, and mount points.
Usage:
lsblkThe output will show:
- Device name (e.g., /dev/sda)
- Size of the devices
- Type (disk, partition)
- Mount points (e.g., /home)
System Uptime — uptime
The uptime command shows how long your system has been running since it was last rebooted. It also lists the load averages for the past 1, 5, and 15 minutes, which is useful for understanding your system’s performance.
Usage:
uptimeThis will show:
- System uptime (time since the system has been up and running)
- Current (1 min), 5 & 15 min Load Averages
