Funny how a lot of us got into computers that way. For me, it was wanting to play Prince of Persia and other DOS games on my cousin's PC when he wasn't around. Figured out what CD and DIR did and how I could run different games by varying the commands. In a few years I was whipping up my own game launcher using AUTOEXEC.BAT, which got me into scripting. I learned to love DOS, and so the eventual transition to Linux was easy for me as I already a CLI fan and I was blown away with how much more powerful the Linux terminal was. It was basically love at first sight.
