Change Ruby version for single command with rbenv

You can switch Ruby version temporarily with rbenv local

But it'd need to be switched back after you're done. Specially for a single command it's kind of pain. In those cases, you can use RBENV_VERSION env variable.

RBENV_VERSION=2.6.3 ruby -v

This might be useful in a shell script or so.
