new to os

[scott mcclellan]

I'm looking to try something different with my machine (or maybe I'm going through a midlife crisis).
 
Currently run Wimdows (point and click), and would like to gravitate back to DOS (this is a thing of the ancient past for me 30 years - on a TRS-80). I know remember extremely little of OS vernacular.
 
Am I biting off more than I can chew, or is there a OS commands for dummies out there, or does FreeBSD have such a critter that one can go through.
 
I'll pour through the FAQ and got hrough the online manuals for now. But it all seems greek. Can someone point me in a diresction to degreek this stuff for me.
 
Thanks,
 
Scott McClellan
