I searched LQ for this, got 277 possibles (I didn't read them all, of course). Googling gave a lot of info, but I only discerned that /sbin/nologin is like a "fake" login, for root to see attempted break-ins -->

Where can I find good info on understanding what this shell is for? I'm going thru TLDP's Intro To Linux guide <<
http://www.tldp.org/guides.html>> and tried the cat /etc/shells command, saw the nologin thing and thought "I'm screwed / rooted already".
TIA
