title: Run and execute a file in Ubuntu Virtualbox
body: <p>I'm using Ubuntu on Virtualbox. When I double-click the .sh file, the option to execute it doesn't come up? I'm very new to Ubuntu and I don't know any of the other ways to get a file to execute. I've tried to use the terminal, but I'm not exactly sure if i did it right. Can anyone tell me how to execute the file?</p>
