Knowing the exact version of your Linux system can be crucial for troubleshooting, managing software, or simply staying informed about your system's capabilities. There are several methods you can use to check the version and distribution of Linux you're running. This article will walk you through the most common ways to gather this information efficiently.
Step-by-Step Methods to Check Your Linux Version
1. Using
/etc/os-release
File
One of the most reliable ways to identify your Linux distribution and its version is by checking the
/etc/os-release
file.
- Open a terminal
- Run the following command:
cat /etc/os-release
This will display detailed information about the distribution, including its name, version, and codename. This method works across most Linux distributions, making it a versatile option.

2. Using
uname
Command
The
uname
command provides essential system information, including the Linux kernel version.
- Run the following command:
uname -a
This will return the kernel version, system architecture, and more. To focus only on the kernel version, use:
uname -r
The uname command is simple but provides valuable insights into your system.
3. Using
lsb_release
Command
If available on your system, the
lsb_release
command is another effective way to check your Linux version and distribution.
- Run the following command:
lsb_release -a
This command gives you details such as the distributor ID, release version, and codename, which can help determine the specific Linux distribution you are running. Learn more about lsb_release in detail.
4. Using
hostnamectl
The
hostnamectl
command offers comprehensive system information, including the Linux version and kernel.
- Run the following command:
hostnamectl
This will provide information like the operating system, kernel version, and machine architecture. This is a great tool for getting both kernel and distribution details.
5. Other Files in
/etc/
Directory
Some Linux distributions have specific files in the
/etc/
directory that contain version information. Depending on the type of system, you can find additional details:
-
/etc/debian_version
for Debian-based systems -
/etc/redhat-release
or/etc/centos-release
for Red Hat-based systems
Checking these files can provide useful insights into the version of the Linux system you are running.
Additional Clarifications
Each of the above methods offers different levels of detail. If you're looking for a basic overview, commands like
uname
might be enough. However, for more comprehensive details, combining multiple methods, such as
/etc/os-release
and
hostnamectl
, can give a fuller picture of your system's specifics.
