Get List of EC2 instances from All regions

ec2.sh

# install aws cli first

for region in `aws ec2 describe-regions --output text | cut -f3`
do
     echo -e "\nListing Instances in region:'$region'..."
     aws ec2 describe-instances --query "Reservations[*].Instances[*].{IP:PublicIpAddress,ID:InstanceId,Type:InstanceType,State:State.Name,Name:Tags[0].Value}" --output=table --region $region
done

it works!

It works as expected, but i had to execute first "aws configure" with empty values on everything except the region, because if you do not have any default region, the CLI complaints it does not know in which region work even when executing "aws ec2 describe-regions" alone.
I also tried to pass as argument --region eu-west-1 but it does not work, you have to do the aws configure thing first to stablish a default region.

@dgacias just export values before the loop

export AWS_PROFILE=<YOUR-PROFILE>
export AWS_DEFAULT_REGION=<SOME-REGION>

you're d man !
