Stops your AWS instance. Check out my post about usage of this script: http://navoshta.com/aws-tensorflow/

aws_stop.sh

#!/bin/bash

# Checks current AWS instance state and stops it if it's running.

AWS_INSTANCE_ID="<Your instance ID here>"

AWS_STATE=$(aws ec2 describe-instances --instance-ids $AWS_INSTANCE_ID --query "Reservations[*].Instances[*].State.Name" --output text)
if [ "$AWS_STATE" == "running" ]; then
	aws ec2 stop-instances --instance-ids $AWS_INSTANCE_ID >/dev/null
	echo -n "The AWS instance is now stopping. It usually takes a while, so feel free to CTRL+C if you don't want to wait till the instance has fully stopped."
	echo "Stopping instance"
	# Wait till the instance has actually stopped.
	while AWS_STATE=$(aws ec2 describe-instances --instance-ids $AWS_INSTANCE_ID --query "Reservations[*].Instances[*].State.Name" --output text); test "$AWS_STATE" != "stopped"; do
		sleep 5; echo -n '.'
	done
	echo " AWS instance stopped. "
else
	echo "AWS instance is not running."
