Reverting your default editor to vi

In their ongoing quest to destroy ubuntu, Team Shuttleworth have decided to change the default editor for visudo to the train wreck that is nano. To change it back we need to change our default editor back to vi.

#sudo update-alternatives --config editor
There are 3 choices for the alternative editor (providing /usr/bin/editor).

Selection Path Priority Status
------------------------------------------------------------
* 0 /bin/nano 40 auto mode
1 /bin/nano 40 manual mode
2 /usr/bin/vim.basic 30 manual mode
3 /usr/bin/vim.tiny 10 manual mode

Press enter to keep the current choice[*], or type selection number: 3
update-alternatives: using /usr/bin/vim.tiny to provide /usr/bin/editor (editor) in manual mode.


As shown in the code box above, you need to choose option 3
