Use AWS CLI and JQ to get a list of instances sorted by launch time

aws ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId,LaunchTime]' --output text | sort -n -k 2
You can do the filtering natively in the aws cli, without using jq (although jq is awesome!)
Sample Output
i-XXXXXXXX	2013-03-05T15:22:34.000Z
i-XXXXXXXX	2013-11-16T18:16:40.000Z
i-XXXXXXXX	2013-09-10T13:54:02.000Z

  • Use the AWS CLI tools to generate a list instances, then pipe them to JQ to show only their launch time and instance id. Finally use sort to bring them out in runtime order. Find all those instances you launched months ago and have forgotten about. Show Sample Output

    aws ec2 describe-instances | jq '.["Reservations"]|.[]|.Instances|.[]|.LaunchTime + " " + .InstanceId' | sort -n
