Fedora Linux

Hi.

I'm using Fedora KDE spin since last year, and have a need for the commands / a script to change power management and lock screen settings via the console (instead of manually going through the GUI). I tried googling the commands, but feel like I didn't even get into the right direction.

If anyone could point me into the correct direction, that'd be greatly appreciated. A ready solution is nice, but I'd also like to know how to find such things by myself in the future.

Sorry if I use the wrong terminology, I used Windows until switched last year.
