rvm determine and install latest version of ruby

Question

So far I only know how to do commands like

rvm 2.0.0

Fortunately Google tells me

The current stable version is 2.0.0-p2

Answer 1

it is enough to:

rvm get stable
rvm use ruby --install --default 

it will update rvm, check for latest ruby - install it if missing - and set as default
