Realtime streaming aws cloudwatch on terminal

Sometime when we deploy our app on ElasticBeanstalk or testing our lambda function, we want to check the log for debugging. Using AWS CloudWatch, we can download and see the logs from various AWS Service. However, sometime we want to check the logs realtime on our terminal. Luckily, there is a CLI app for that.
