Hello All,
Ubuntu is a Linux based operating system and an alternative to Windows and Mac OSs.
Users of Ubuntu can choose their desktop environment and switch seamlessly from one to another at startup.
If the user only installs one desktop environment, he or she doesn't have to wonder which one is in use.
I use multiple environments and sometimes forget which one I am running.
Of course, I could restart my computer and pay attention to the one that I selected but there is a quicker, simpler solution.
Open the Terminal and type echo $XDG_CURRENT_DESKTOP
Doing so will reveal the name of the environment that you are currently running
