How to Check Linux OS Version
In the vast world of Linux, knowing your operating system’s version is crucial for several reasons. Whether you are a seasoned Linux user or just starting out, understanding your OS version can help you identify compatible software, troubleshoot issues, and keep your system up-to-date. In this article, we will explore various methods to check the Linux OS version on different distributions.
Using the `lsb_release` Command
One of the most common and straightforward methods to check the Linux OS version is by using the `lsb_release` command. This command is available on most Linux distributions and provides detailed information about the system’s version, release, and distribution.
To use the `lsb_release` command, open your terminal and type:
“`
lsb_release -a
“`
This will display a wealth of information, including the distribution name, release number, codename, and other details. If you only want to check the release number, you can use the `-r` option:
“`
lsb_release -r
“`
Using the `cat` Command with `/etc/os-release` File
Another method to check the Linux OS version is by examining the `/etc/os-release` file. This file contains various pieces of information about the system, including the version and distribution name.
To view the contents of this file, use the `cat` command:
“`
cat /etc/os-release
“`
This will display a list of key-value pairs, such as `PRETTY_NAME`, `VERSION`, and `ID`. The `VERSION` field will show the release number of your Linux distribution.
Using the `uname` Command
The `uname` command is a versatile tool that provides system information, including the kernel version. While it does not provide the complete OS version, it can be helpful in identifying the kernel version, which is often closely related to the distribution’s release.
To check the kernel version, open your terminal and type:
“`
uname -r
“`
This will display the kernel release number.
Using the `hostnamectl` Command
The `hostnamectl` command is a more user-friendly alternative to `lsb_release` and `uname`. It provides a summary of the system’s hostname, operating system, and kernel version.
To use the `hostnamectl` command, simply type:
“`
hostnamectl
“`
This will display a brief overview of your system, including the OS version and kernel version.
Conclusion
Checking the Linux OS version is an essential task for every Linux user. By using the methods outlined in this article, you can easily determine the version of your Linux distribution, kernel, and other important system details. Whether you are troubleshooting, upgrading, or simply curious about your system, knowing your OS version is a valuable piece of information.
