How to Find the Linux OS Version

Identifying Your Linux Distribution

The first step in finding the Linux OS version is to identify your operating system. Here’s how to do it:

• Check your system’s system identification information. This can be done by typing cat /etc/os-release or cat /etc/Release in your terminal. This will display a list of installed distributions, their versions, and other relevant information.
• Alternatively, you can check your system’s package manager configuration. Most Linux distributions have a package manager that stores metadata about installed packages, including their versions. You can check the package manager configuration by typing ls /etc/apt/sources.lst or ls /etc/filelist.lst.
• You can also check your system’s system logs for more information. The system logs often include version information about installed packages.
