What is the purpose of the 'sudo' command?

• A. To run commands without administrator privileges
• B. To execute commands as another user
• C. To copy files across directories
• D. To install system updates

Answer: (B)

The 'sudo' command is primarily used to execute commands with the privileges of another user, typically the superuser or root. This capability is crucial in a multi-user environment, allowing users to perform administrative tasks without needing to switch accounts or log in as the superuser directly. This not only enhances security by limiting the number of users who have root access but also allows for better accountability, as actions performed with 'sudo' can be logged. Using 'sudo' enables a user to temporarily elevate their permissions to perform tasks that require higher privileges, such as modifying system files, managing user accounts, or installing software. This use of permissions is fundamental to maintaining the overall integrity and security of the system. While other options may sound plausible, they do not accurately capture the primary function of the 'sudo' command. The command is not for running commands without administrator privileges, copying files across directories, or specifically installing system updates, but rather to grant temporary elevated access as needed.
