Execute code over all AWS regions

aws-regions-cmd.sh

#!/bin/bash

## oneline : for r in $(aws ec2 describe-regions --query "Regions[].{Name:RegionName}" --output text --region ca-central-1); do echo "---------- AWS Region : $r ----------" ; echo "hello world"; done

for r in $(aws ec2 describe-regions --query "Regions[].{Name:RegionName}" --output text --region ca-central-1); 
do 
    echo "---------- AWS Region : $r ----------" ; 
    echo "hello world"; 
done
    

Notes :
the --region ca-central-1 is not necessary if you defined a default region in your AWS cli configuration; adding it makes it generic.
