Last day I was trying to edit the crontab task but the default editor or the setup editor drove me crazy, I didn't know how to save, how to insert, how to exit ... Here I present a way to change the crontab editor:

- The only thing you have to do is to change the environment variable VISUAL. So, we can use the editor we want:

export VISUAL='pico -w' -> to use pico editor
export VISUAL='vim' -> to use vim editor

If you want to aply this variable to all user console, include the export in the .bashrc file located in the user home.
