How to Use Su with FreeBSD 11?
I understand that the root user doesn’t have a password, and that, for security reasons, direct root access isn’t available via SSH. That said, there are some instances, such as viewing the contents of directories created with sudo, where you need su, otherwise the prompt isn’t returned to the right user.
Unfortunately, sudo su only results in Su: sorry.
How do I run the su command in FreeBSD 11?
