Linux is an open-source operating system kernel. It’s used in various distributions (distros) like Ubuntu, Fedora, Debian, and more. Identifying your specific Linux distribution and version requires using the command line.
Using the `uname` Command
The uname command is a fundamental utility in Linux for retrieving system information.
Open a terminal window. Type uname -a and press Enter. The command will display detailed information about your system, including the kernel name, hostname, kernel release, kernel version, and hardware architecture.
This command can be daunting for new users, as it provides a lot of raw information.
Using the `/etc/os-release` File
Most modern Linux distributions include a file called /etc/os-release that contains information about the operating system.
Open a terminal window. Type cat /etc/os-release and press Enter. The cat command will display the contents of the file, which include the distribution name, version, and other relevant details. The NAME variable indicates the distribution name (e.g., Ubuntu, Fedora, Debian), and the VERSION variable indicates the version number.
This method is generally considered more reliable and user-friendly than uname.
Using Distribution-Specific Commands
Some Linux distributions have specific commands for displaying the OS version. For example:
- For Debian-based systems (including Ubuntu):
lsb_release -a - For Red Hat-based systems (including Fedora and CentOS):
cat /etc/redhat-release
These commands provide a more user-friendly output with clearer information about the distribution name and version.
Identifying Your Operating System on Mobile Devices
Mobile devices, such as smartphones and tablets, also run operating systems. The two dominant mobile operating systems are Android and iOS.
Identifying Your Android Version

Open the Settings app on your Android device. Scroll down to “About phone” or “About tablet” (the exact wording may vary depending on the device manufacturer). Tap on “About phone” or “About tablet”. Look for the “Android version” entry. This will display the Android version number (e.g., Android 10, Android 11, Android 12).
You may also find information about the security patch level and kernel version on this page.
Identifying Your iOS Version
iOS is the operating system developed by Apple for its iPhone, iPad, and iPod Touch devices.
Open the Settings app on your iOS device. Tap on “General”. Tap on “About”. Look for the “Version” entry. This will display the iOS version number (e.g., iOS 15, iOS 16, iOS 17). This page also provides other useful information, such as the device name, model name, serial number, and available storage space.
Considerations for Virtual Machines
If you are using a virtual machine (VM), the process of identifying the operating system is the same as if you were using a physical machine. The operating system running inside the VM is independent of the host operating system. You’ll need to use the methods described above for Windows, macOS, or Linux, depending on the OS installed within the VM.
Why Use The Right Method
Using the right method for your operating system ensures you get accurate information. Trying to use a Windows method on macOS, or vice versa, won’t work. It’s like trying to use a screwdriver to hammer a nail – the tools are not compatible. Knowing the correct method helps you avoid confusion and frustration.
Additional Tips
Pay attention to the specific wording used by each operating system when displaying the version information. For example, Windows uses terms like “Edition” and “Version,” while macOS uses the term “macOS” followed by the version name. These subtle differences can help you quickly identify the OS.
If you’re still unsure about your operating system, consider searching online for images or screenshots of the “About” page or System Information window for different OS versions. This can help you visually compare your system to known examples.
