How to Check Ubuntu Version Using Terminal
Checking your Ubuntu version is an essential step when you are troubleshooting or looking for specific software compatibility. Ubuntu, being a popular Linux distribution, offers a variety of versions, each with its own set of features and support periods. In this article, we will guide you through the process of checking your Ubuntu version using the terminal, the command-line interface of your Ubuntu system.
Using the ‘lsb_release’ Command
One of the simplest ways to check your Ubuntu version is by using the ‘lsb_release’ command. This command provides detailed information about the Linux distribution, including the version number. Here’s how to use it:
1. Open your terminal. You can do this by pressing Ctrl + Alt + T or searching for “Terminal” in the Ubuntu Dash.
2. Type the following command and press Enter:
“`bash
lsb_release -a
“`
3. The terminal will display a list of information about your Ubuntu system, including the release identifier, codename, description, and version number.
Using the ‘cat’ Command
Another method to check your Ubuntu version is by using the ‘cat’ command to read the contents of the ‘/etc/os-release’ file. This file contains various information about your operating system, including the version. Here’s how to do it:
1. Open your terminal.
2. Type the following command and press Enter:
“`bash
cat /etc/os-release
“`
3. Look for the “VERSION” line in the output. This line will display your Ubuntu version.
Using the ‘uname’ Command
The ‘uname’ command is a more general command that can be used to display information about your system, including the kernel version. While it doesn’t directly show the Ubuntu version, you can use it to cross-reference the version with the Ubuntu release history. Here’s how to use it:
1. Open your terminal.
2. Type the following command and press Enter:
“`bash
uname -r
“`
3. The terminal will display the kernel version. You can then compare this version with the Ubuntu release history to determine your Ubuntu version.
Conclusion
Checking your Ubuntu version using the terminal is a straightforward process that can help you with various tasks, such as troubleshooting or finding compatible software. By using the ‘lsb_release’, ‘cat’, and ‘uname’ commands, you can easily determine your Ubuntu version and ensure that you are using the correct software and updates for your system.
