168. What is a Superuser in Unix?
Superuser is a special user account. It is used for Unix system administration. This user can access all files on the file system. Also Superuser can
also run any command on a system.
Generally Superuser permission is given to root user.
Most of the users work on their own user accounts. But when they need to run some additional commands, they can use su to switch to Superuser
account.
It is a best practice to not use Superuser account for regular operations.
