how to set micro as default for sudo?

[lockcher4]

Ubuntu 20.04
Shell: bash

export VISUAL=micro
export EDITOR=micro
export SUDO_EDITOR=micro

it doesn't work for sudo

From Stack Overflow:

To make use of the editor in visudo actually, we need to handle that sudo does not keep the environment variables by normally. > The option -E changes that.

sudo -E visudo

Without the -E here, you would end up with a default of nano again.

After executing sudo -E visudo, try executing visudo /etc/some-file-that-needs-sudo.

I added the line:
Defaults env_keep += "EDITOR VISUAL"
to the sudoers.tmp file and it started working) thanks
