What command changes the Group setting for a directory?
chmod
does not change owner. It changes permissions. chown
changes owner (and group if need be) and chgrp
changes group.
You can use
chown {-R} [user]{:group} [file|directory]
to set user and group ownership where -R
does everything that is inside directory
.
So sudo chown -R rinzwind:rinzwind /tmp/
would set /tmp/
and everything in it to user rinzwind and group rinzwind.
There is also
chgrp {-R} [group] [file|directory]
if you do not need to touch the user permissions and only need to set the group.
Oh and you can check what group a user belongs to with groups {username}
.
In addition to Rinzwind's answer, you might also use chown :group [file|directory]
to change the group only and leave the owner intact.
