Here is the command that you can use to get the master username of your RDS:

    --region us-east-1
    --db-instance-identifier YOUR-RDS-IDENTIFIER-HERE
    --query 'DBInstances[*].MasterUsername'

Note: Replace the prod with your aws profile and YOUR-RDS-IDENTIFIER-HERE with your rds instance identifier
