How To Get Linux Version : Command Line Version Check

by

Knowing which Linux version you are running is crucial for software compatibility, and a single terminal command will give you that information. If you’ve ever wondered how to get linux version details quickly, you are in the right place. This guide covers every method, from simple commands to checking graphical interfaces, so you never have to guess again.

Whether you are a beginner or a seasoned sysadmin, identifying your Linux distribution and kernel version helps with troubleshooting, installing packages, and ensuring security updates. Let’s jump right in.

Why You Need To Know Your Linux Version

Every Linux system is different. Ubuntu, Fedora, Debian, and Arch all have unique package managers and system tools. Running the wrong command or installing incompatible software can break your setup. Knowing your version prevents these issues.

Also, security patches are version-specific. If you don’t know your release number, you might miss critical updates. This is especially important for servers and production environments.

How To Get Linux Version Using The Terminal

The terminal is the fastest and most reliable way. Here are the top commands you can use.

Using The lsb_release Command

Most modern Linux distributions include the lsb_release tool. It shows distribution-specific information.

  1. Open your terminal (Ctrl+Alt+T on most systems).
  2. Type: lsb_release -a
  3. Press Enter. You’ll see output like this:

    4. Distributor ID: Ubuntu
    Description: Ubuntu 22.04.3 LTS
    Release: 22.04
    Codename: jammy

    If the command is not found, install it with sudo apt install lsb-release (Debian/Ubuntu) or sudo yum install redhat-lsb-core (RHEL/CentOS).

    Checking The /etc/os-release File

    Almost all Linux systems include this file. It’s a standard way to identify the OS.

    Run: cat /etc/os-release

    You’ll see variables like NAME, VERSION, and ID. For example:

    NAME="Ubuntu"
    VERSION="22.04.3 LTS (Jammy Jellyfish)"
    ID=ubuntu

    This method works even on minimal installations without extra tools.

    Using The hostnamectl Command

    On systems with systemd (most modern distros), hostnamectl gives you both OS and kernel info.

    Type: hostnamectl

    Output includes:

    Operating System: Ubuntu 22.04.3 LTS
    Kernel: Linux 5.15.0-91-generic

    This is one of the cleanest outputs for quick reference.

    How To Get Linux Version For Kernel Details

    Sometimes you need the kernel version, not just the distribution release. Here’s how.

    The uname Command

    The uname command is your go-to for kernel information.

    • uname -r shows the kernel release (e.g., 5.15.0-91-generic).
    • uname -a shows all system info, including architecture and hostname.

    This is universal across all Linux distributions.

    Checking /proc/version

    Another reliable source is the /proc/version file.

    Run: cat /proc/version

    You’ll see something like:

    Linux version 5.15.0-91-generic (buildd@lcy02-amd64-086) (gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0, GNU ld (GNU Binutils for Ubuntu) 2.38)

    This includes the compiler used to build the kernel, which can be useful for debugging.

    How To Get Linux Version Without The Terminal

    Not everyone likes the command line. Here are graphical methods.

    Using System Settings

    On Ubuntu and many GNOME-based distros:

    1. Open “Settings” from the application menu.
    2. Go to “About” or “System.”
    3. Look for “OS Name” and “Version.”

    On KDE Plasma, the information is under “System Settings” > “About This System.”

    Checking The Login Screen

    Some display managers show the version on the login screen. For example, GDM (GNOME Display Manager) often displays the distribution name and version at the bottom.

    Using Neofetch Or Screenfetch

    These are third-party tools that display system info in a visually appealing way. Install them with your package manager:

    • sudo apt install neofetch (Debian/Ubuntu)
    • sudo dnf install neofetch (Fedora)

    Then run neofetch. It shows the OS logo, kernel, uptime, and more.

    How To Get Linux Version On Servers

    Servers often lack a GUI. Use these commands for headless systems.

    Using cat /Etc/*release

    This wildcard command shows all release files in one go.

    Run: cat /etc/*release

    You’ll see content from /etc/os-release, /etc/redhat-release, /etc/debian_version, etc.

    Checking /etc/debian_version Or /etc/redhat-release

    Debian-based systems have /etc/debian_version. Red Hat-based systems have /etc/redhat-release.

    Example for Debian: cat /etc/debian_version might output “11.7.”

    Example for CentOS: cat /etc/redhat-release might output “CentOS Linux release 7.9.2009 (Core).”

    How To Get Linux Version On Older Systems

    Older distributions may not have modern tools. Try these fallbacks.

    Using cat /Etc/issue

    This file often contains a simple version string.

    Run: cat /etc/issue

    Output might be “Ubuntu 18.04.6 LTS \n \l.”

    Using cat /Etc/gentoo-release Or Similar

    Some distros have their own release files. For example, Gentoo uses /etc/gentoo-release, Slackware uses /etc/slackware-version.

    Check for any file in /etc ending with -release or -version.

    How To Get Linux Version For Docker Containers

    Inside a container, you might not have full system info. Use these methods.

    Checking The Host Kernel

    Containers share the host kernel. Run uname -r inside the container to see the host kernel version.

    Using cat /Etc/os-release Inside The Container

    If the container is based on a standard image, this file exists. For Alpine-based containers, use cat /etc/alpine-release.

    Common Mistakes When Checking Linux Version

    Avoid these pitfalls.

    • Confusing kernel version with distribution version. They are different.
    • Assuming all commands work on all distros. lsb_release may not be installed by default.
    • Relying on /etc/issue which can be modified by users.

    Always verify with multiple commands if you are unsure.

    How To Get Linux Version In Scripts

    Automate version checking in bash scripts.

    Using source /Etc/os-release

    You can source the file to get variables:

    source /etc/os-release
    echo $NAME $VERSION

    Parsing lsb_release Output

    Use lsb_release -rs to get just the release number (e.g., 22.04).

    How To Get Linux Version For Different Distributions

    Each family has its quirks.

    Debian And Ubuntu

    Use lsb_release -a or cat /etc/debian_version. Ubuntu also has /etc/upstream-release/lsb-release for LTS info.

    Red Hat, CentOS, Fedora

    Use cat /etc/redhat-release or rpm -q centos-release. Fedora has /etc/fedora-release.

    Arch Linux

    Arch is rolling release, so version is less relevant. Check /etc/arch-release (usually empty) or pacman -Qi filesystem.

    OpenSUSE

    Use cat /etc/SuSE-release or zypper --version.

    How To Get Linux Version On WSL

    Windows Subsystem for Linux has its own quirks.

    Run cat /etc/os-release inside WSL. The kernel version is shown with uname -r, but it’s a custom Microsoft kernel.

    You can also check the WSL version with wsl --version in PowerShell.

    How To Get Linux Version For Embedded Systems

    Embedded Linux (like Raspberry Pi OS) uses similar methods. Check /etc/os-release or cat /etc/rpi-issue for Raspberry Pi.

    For Yocto-based systems, look for /etc/build or /etc/version.
