Need Linux help on what to input in terminal for steps below.

Create a Directory Administration notified you that Dustin needs a directory right away. The /var directory is a good place for this directory. By the way, Dustin should be a part of the Administration group. Make sure the user and group permissions are all set accordingly.

Also only the owner and group should be able to do everything. Everyone else should be banned from using that directory.

Create a directory on the server named Sa3De in to the /var directory. Owner: dustin Group: administration Permissions: owner and group can read, write and execute; others have no permissions.
