The easiest way to remember which word to use is to remember that you're is a contraction of the words you are. You're = you are. Keep this in your mind if you get a little stuck. Whereas, your = belonging to a person.
I'm using Fedora34, there are no such thing as files on the desktop. After several hours, I finally found the CLI.
java -jar '/home/yourusername/Downloads/OSBot 2.6.32.jar'
Hopefully that helps someone.
Have a nice day!
