How can I kill all my EC2 instances from the command line?

Question

How can I kill all my instances from the command line? Is there a command for this or must I script it?

Answer 1

This is an old question but thought I'd share a solution for AWS CLI:

aws ec2 terminate-instances --instance-ids $(aws ec2 describe-instances --filters  "Name=instance-state-name,Values=pending,running,stopped,stopping" --query "Reservations[].Instances[].[InstanceId]" --output text | tr '\n' ' ')

If hackers have disabled accidental instance termination, first run this command:

aws ec2 describe-instances --filters  "Name=instance-state-name,Values=pending,running,stopped,stopping" --query "Reservations[].Instances[].[InstanceId]" --output text  |  xargs --delimiter '\n' --max-args=1 aws ec2   modify-instance-attribute  --no-disable-api-termination --instance-id

Answer 2

AWS Console and Elasticfox make it pretty easy.

A command-line solution can be achieved in one-line using the EC2 API tools:

for i in `ec2din | grep running | cut -f2`; do ec2kill $i; done
