Came over from Windows and to be able to use a simple command to do something that had taken many steps was like the heavens opening and Angels singing. I've since explored all the switches and ways to modify the command to make life even easier.
I'm sure I use more, but when I first took over our Red Hat environment and started learning Linux this was easily the most impactful to me.
