How to switch back from root user in ubuntu?

Answer 1

$Switch \: To \: The \: Root \: Use \: press \: alt \: and \: t$

In order to switch to the root user you need to open a terminal by pressing ALT and T at the same time.

If you ran the command with sudo then you will be asked for the sudo password but if you ran the command just as su then you will need to enter the root password.
