Why does visudo lock the sudoers file?
Since the sudoers file determines which users can run administrative tasks, those requiring superuser privileges, it is a good idea to take some precautions when editing it, and that’s what visudo does. It locks the sudoers file so it cannot be edited by anyone else simultaneously.
How can I change the default editor in visudo?
Visudo has a built in list of supported editors that can be used, and you can change which it will use by setting the “EDITOR” environment variable on the command line like this: This will set nano as the default editor. To save this permanently add the same line to the .bashrc file in your home directory.
How do I Save changes to visudo in nano?
In nano: press Ctrl+X, then y to confirm you want to save changes. Then press Enter without changing the default filename ( visudo will know what to do). Once your text editor session finishes, the control will be back to visudo which will do the checks and flag any issues.
