Questo esempio concede full control a due AWS utenti (user1@example.com e user2@example.com) read l'autorizzazione a tutti:

aws s3api put-bucket-acl --bucket MyBucket --grant-full-control emailaddress=user1@example.com,emailaddress=user2@example.com --grant-read uri=http://acs.amazonaws.com/groups/global/AllUsers
