To edit the /etc/sudoers file in the vi text editor without risking any change conflicts from other users on the system, use the visudo command:

sudo visudo

To learn more about how to configure the the /etc/sudoers file, see Adding User Authorizations in the sudoers File and the visudo(8) manual page.

Administrators can also use the visudo command to manage permission files for individual users in the /etc/sudoers.d/ directory. For more information, see Adding User Authorizations in the sudoers.d Directory.
