What can you do with the command su besides give yourself root privileges?

The su command, which stands for "substitute user," allows you to switch to a different user account in a Unix-like operating system. Besides granting root privileges, it can be used to run commands or scripts as another user, which is useful for testing permissions or executing user-specific applications. Additionally, it can help in troubleshooting by allowing access to user-specific configurations and environments without logging out.
