The Chown command and the chgrp (change group command) sounds like they are the same. They seem to have the same functions. Can they be used in either option??
They are not the same. Refer to the man pages, or the "Linux Commands" entry at top of this page in the navigation bar. https://www.howtoforge.com/linux-commands/#chgrp https://www.howtoforge.com/linux-commands/#chown
