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

I don't know of a way to have rvm just install the latest version automatically, but here's three simple commands using just rvm:

rvm reload
rvm list known # This will show all the available versions, including the latest
rvm install  # Replace  with the latest shown by the last command
