I use Centos $9.$ Please help step by step and all the command need for this Lab $7\mathrm{.}1$

$1.$ Set up a shared group environment. If you haven't created these directories in a previous

exercise yet, create two directories: $/$data$/$account and $/$data$/$sales$.$ Make the group sales the

owner of the directory sales, and make the group account the owner of the directory account.

$2.$ Configure the permissions so that the user owner $($which must be root$)$ and group owner have

full access to the directory. There should be no permissions assigned to the others entity.

$3.$ Ensure that all new files in both directories inherit the group owner of their respective

directory. This means that all files that will be created in $/$data$/$sales will be owned by the group

sales, and all files in $/$data$/$account will be owned by the group account.

$4.$ Ensure that users are only allowed to remove files of which they are the owner.
