Linux is an astounding service and concept. Yes! I heard of Linux many years ago but it never made it into the mainstream home users. In the late 1960s I learned to go into does, fix or change commands. When MSW finally invaded the scene, over time I became a MSW dunce-- point, click, guess, and default kept me going all these years and fear.
Now at age 73, I'm learning linux almost solo except for a younger friend who dumped all things MSW, and like me, we are going all Linux OS & programs. Fear has been replaced with caution, and caution fuels learning, hours of it. Learning my way around the forums and huge support I'm confident this will be one of the most rewarding things I will do in my senior years.
Will be back many times I'm certain but I will make search attempt as suggested by Marc Deop.
