List objects in a bucket
If there are any files at the bucket level, then this command will return the list of files. If there are only folders/prefixes under the bucket, then it will return the top level folder/prefix names of that bucket. Keep in mind, if you try to list objects that you do not have access to, you will get an access denied error.aws s3 ls s3://<bucketName>
