nano getawsinstances.sh

!/bin/bash echo “Grabbing instances in all regions, please wait..” for region in aws ec2 describe-regions --output text | cut -f4; do echo “Listing Instances in region:’$region’…” aws ec2 describe-instances –region $region \ –output table \ –query “Reservations[].Instances[].{ InstanceId:InstanceId, Type:InstanceType, AZ:Placement.AvailabilityZone, KeyName:KeyName, Name:Tags[?Key==`Name`]|[0].Value, Project:Tags[?Key==`project`]|[0].Value, IP:PublicIpAddress, State:State.Name, CPUcores:CpuOptions.CoreCount, CPUThreads:CpuOptions.ThreadsPerCore }” done
