What is the difference between SU and SUDO?

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.

SU and SUDO are different commands in Linux system. SU stands for “superuser” or “root user”. SU enables a user to switch user and also run a command under other user ID. To run the SU command, you need a root password to open up a root shell. After this is done, you now have access as the root user. Whatever you do during the session is acknowledge and run as root.

SUDO stands for “Super User Do”. This command allows a user to run as root from the current user. To use SUDO, you will be required to use your password again for security purposes. The advantage of SUDO is that you do not have to change your identity to run root. The SUDO command does not require activation of the root shell. Hope you find this information helpful.

Sudo and Su are terms that are used in Linux. SU means superuser. This will make sure that the Linux system is executed properly without the need to have any other additional options. The only requirement is that you have a password for this. SUDO will be able to run a single command with root permissions.

If you are going to use this, you need to place your user account password and make sure that you will run it with root permissions. One thing to remember is that su will require you to share your password to other users while sudo will not activate the root shell. 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.
