sudo allows a permitted user to execute a command as the superuser or another user, as specified by the security policy.
Users can use “sudo” command to run terminal as administrator in ubuntu. Simply type sudo before the rest of your command. The command “sudo” stands for “substitute user do.” When a user executes sudo to the beginning of a command, the command runs as root. Note that you will be prompted to enter your password before sudo runs the command.
Users can also use “gksudo” before running a command that. It is for a program with a Graphical User Interface (GUI). In Linux Ubuntu, for security reasons, using “sudo” is not recommended to open GUI applications.

Users can use Sudo command to tun terminal as root in Ubuntu. Use the sudo -i command. Open Terminal and type “sudo -i” command as follows:
$ sudo -i
The sudo -i command command will give you superuser access with root’s environment variables. Once executed, the prompt will change from $ to #, indicating you have root access.
