User privileges refer to the permissions and rights granted to users within a system, application, or network. These privileges determine what actions a user can perform, such as accessing files, modifying data, or executing specific commands. They are essential for maintaining security and ensuring that users can only perform tasks relevant to their roles. Proper management of user privileges helps prevent unauthorized access and protects sensitive information.

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.
