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 employed to alter the group ownership of files or directories.

• \texttt{chown} modifies the owner (user) of a file.
• \texttt{chmod} alters the permissions of a file.
• \texttt{id} shows the current user and group details.
• \texttt{chgrp} exclusively adjusts the group ownership.

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