GNOME is a desktop environment – in plain terms, it is an operating system’s graphical interface (many OSes use GNOME as their graphical interface). GNOME has many components, including support libraries, window/display managers and one composer, and various GNOME applications.
GNOME is free and open-source software. It is mostly aimed towards Linux computers but may be run on BSD. We will be discussing multiple ways to check your Ubuntu version, both by CLI (Command Line Interface) and GUI (Graphical User Interface). Let’s begin!
What
is Command-Line?
Earlier, when GUI was not introduced, commands were typed into the command-line interface to communicate with the system’s OS.
In the command-line interface, the user interacts with the operating system in text commands. The commands are then executed by the kernel of the operating system for further processing. Using a command-line interface is preferred over GUI as it adds more efficiency and speed to the execution of the instructions. Besides, while working with virtual machines, one needs to interact with the machine using CLI instead of GUI.
Checking Version of Ubuntu Using the Standard cat Command
cat command in Linux is used to display the content of one or more files present in your machine. It can also be used to create new files and add content to them at creation. To view a file content using the cat command, use the below syntax:
Type following command on the terminal:
Checking Version Using lsb_release Utility
The lsb_release utility displays the LSB (Linux Standard Base) information about the Linux distribution.
A lsb_release tool that provides LSB (Linux Standard Basis) information for the Linux distribution is the best technique for checking your Ubuntu release.
Checking Version Using hostnamectl Command
Another way to check the Ubuntu version is by the following command:
You may search and modify the hostname and associated parameters with the hostnamectl command. One can also display the distribution name and kernel version of their Linux.
Checking the Ubuntu Version Using GUI
Go to the settings and click on the About button. The following tab will get displayed. You may check the GNOME version as highlighted in the sample image.
Conclusion
We have seen multiple ways to check the version of your Ubuntu OS. It is good to verify the version of Ubuntu to fix and implement for security and performance reasons. Many packages are not compatible with your current OS. Checking the status of the OS version will thus assist you in upgrading your OS and install the required packages to another version. Using Command Line Interface to check the version of your OS is quite helpful when working with virtual machines where you have most of the access to the command line interface and not the GUI.
