Honestly, if all you've ever experienced in regards to terminals is windows CMD, then you really haven't seen much. I mean that possitively. Actually, it will give you a far worse impression on what using a Linux / Unix terminal can be like (speaking as someone who spent what feel's like years in terminals, of which the least amount in windows CMD).

I suggest to simply play around with a Linux terminal (e.g. install VirtualBox,.then use it to install e.g. Ubuntu, then follow some simple random "Linux terminal beginner tutorial" you can find online).
