Unix, Minix and Linux. I think it is something how they all came about.

1953 was the first true OS according to book by Peter Salus, "A quarter
century of Unix". 54 years of the computer OS.

Yea I was programming in'basic' language back in the 70's.
If I remember correctly, I think that it took me about thirty mins back
then just to write the code to make a ball bounce accross a black
screen.LOL

Did it ever seem like magic to ya? My first computer was an old Radio
Shack Color Two. I liked playing with the Fractals. I remember the first
time from going along with the book I could change the color of the
screen. All of them old commands were something. I screwed up my first
set of DOS 6 floppies by using the AutoExecBat on the first
floppy. I took Linux at College. They called it DOS 2. I bet
Linus Torvalds would have blew a gasket if he heard them at the College
calling Linux DOS 2. My professor had to help me with Linux.
Another professor actually took an old computer using Linux to make a
physical firewall. That did it. I tried to learn Linux. Then I found out
what a memory hog the Windows kernel is. Then the cooperation different
users could add to the kernel. That is why I call DOS dumb. You have to
learn as you go to understand Linux so Linux is not dumb. Just as you
learn the programming from scratch you can learn Linux but DOS and
Windows it is so much about being user friendly. I screwed up Windows
3.1 the first time I used it by using the command line.
