Su and Sudo are both used in Linux, but they have some differences that you should know to gain a better understanding of how each should be applied. These are used to gain root privileges. You will use “Su” when you would like to be the superuser.

This can be used to different user accounts that you please. For example, you can type in “Su Sue,” and you will be switched to Sue’s account. Sudo will require the password of the account, and when you input it, you will gain access to the account for about 15 minutes before you will be required to place the password again.

With these details, you can decide which one is the better option for you to use.

The terms SU and SUDO are often seen on Linux. They are used to run different commands with root permissions to do anything to the system. SU or Super User is where the user executes with no additional options where all you have to do is type in the root account’s password. You can also switch accounts as long as you know the password of the account you are switching in then you could enter it.

When you are done running commands, you should key in exit to leave the root shell. On the other hand, SUDO only runs in a single command with little root privileges. The system prompts you for the current user password before running commands. You can run commands for 15 minutes before Ubuntu will require you to type in again the password.
