CLI
AWS CLI

Este exemplo concede full control para dois usuários da AWS (user1@example.com e user2@example.com) e permissão read para todos:

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

Consulte http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketPUTacl.html para obter detalhes sobre ACLs personalizadas (os comandos da ACL s3api, como put-bucket-acl, usam a mesma notação abreviada de argumentos).
