Deleting .rbenv from Linux

If you installed rbenv using apt-get, then

apt-get remove rbenv

or

sudo apt-get purge --auto-remove rbenv

is a good first step. Next steps should be: nuke the ~/.rbenv directory and all references to "rbenv" in ~/.bashrc, .bash_profile, or similar shell initialization files.

Michael Durrant helped me with his comment, i was an idiot not to think that way in the first place, i just had to do:

apt-get remove rbenv

Since i didn't install it through a package manager, rather followed the instructions on GitHub, i thought that it wasn't appropriate (although i first tried apt-get uninstall instead of apt-get remove).
