How to remove rvm (ruby version manager) from my system?
How can I uninstall (or reinstall) RVM on Ubuntu 9.10? I messed up my current installation.

It’s easy; just do the following:
rvm implode
or
rm -rf ~/.rvm
And don’t forget to remove the script calls in the following files:
~/.bashrc~/.bash_profile~/.profile
And maybe others depending on whatever shell you’re using.
