# NOTE: Originally taken and modified from: https://gist.github.com/mansurali901/ca7e02c520d494948c58
# modified to use region name as parameter
# (For use when you mistakenly commit your .env to github and your AWS gets flooded with 50k$/day bitcoin mining instances, like me)
# May be best to install: https://github.com/awslabs/git-secrets

# BUG(kit) - for some reason it only does 10 instances at a time.  There is probably an option to do it

# USAGE:
# bash terminate-ec2-instances.sh <REGION>

region=$1

cat instances-list |awk '{print $1}' >instances-list2
