linux - Why less when you can have more? (Pagers on *Nix)

Why do Linux people and most programs -- Ruby commands, for instance -- use less instead of more. Isn't more bigger, nicer, and better? What is the advantage to less?

Answer

Originally more only allowed forward motion in the file while less allowed you to move freely in the viewed file.

Modern version of more is more versatile.

I think the two wiki pages for more and less shows the current difference quite well.
