ubuntu 에디터 잘못 선택 했을 시 초기화 방법(크론탭도 해당)

On Ubuntu the configuration file is called ~/.selected_editor

With the following command you can select the default editor again:

$ select-editor

Removing the file in your home directory also works.

$ rm ~/.selected_editor

Only setting the variables $VISUAL or $EDITOR will work but is only persistent if you write it to a script which is executed in your environment.

Add to your rc file

$ echo "export VISUAL=/usr/bin/vi" >> ~/.bashrc

But i wouldn't recommend to use the last solution.
