How to Check the Linux OS Version
In the world of Linux, knowing your operating system’s version is crucial for a variety of reasons. Whether you’re troubleshooting an issue, looking for compatibility with software, or simply curious about the specifics of your system, understanding the Linux OS version is essential. This article will guide you through the process of checking the Linux OS version on different distributions, including Ubuntu, CentOS, and Fedora.
Checking the Linux OS Version on Ubuntu
For Ubuntu users, the process is straightforward. Open a terminal window and type the following command:
“`
lsb_release -a
“`
This command will display detailed information about your Ubuntu distribution, including the version number. The output will include the release identifier, codename, description, and other relevant details.
Checking the Linux OS Version on CentOS
CentOS users can also check their OS version using the `lsb_release` command. Open a terminal and enter:
“`
lsb_release -a
“`
This will provide you with the same information as in Ubuntu, including the CentOS version number.
Checking the Linux OS Version on Fedora
For Fedora users, the process is slightly different. Open a terminal and type:
“`
cat /etc/fedora-release
“`
This command will display the Fedora version number and other relevant information, such as the release identifier and codename.
Alternative Methods for Checking the Linux OS Version
If you prefer not to use the `lsb_release` command, there are alternative methods to check your Linux OS version. One such method is to examine the contents of the `/etc/os-release` file. Open a terminal and type:
“`
cat /etc/os-release
“`
This command will display a summary of your OS version, including the ID, version, codename, and other details.
Conclusion
Checking the Linux OS version is a fundamental skill for any Linux user. By following the steps outlined in this article, you can easily determine the version of your Linux distribution, whether you’re using Ubuntu, CentOS, or Fedora.
