Question

To change group ownership, which of the following command will be used?

• A. chown
• B. id
• C. chmod
• D. chgrp

Hint:

Use chgrp to change the group owner without affecting user ownership or permissions.

Answer 1

The Correct Option is D

The \texttt{chgrp} command in Linux/Unix is used to change the group ownership of a file or directory.

• \texttt{chown} changes the owner (user) of a file.
• \texttt{chmod} changes the permissions of a file.
• \texttt{id} displays the current user and group information.
• \texttt{chgrp} specifically modifies the group ownership.

Example usage: \[ \texttt{chgrp newgroup filename} \]
