This gist is to get all Network ACLs for your AWS account from all regions to review. Make sure you have aws cli setup

getAllNetworkACLS.sh

#!/bin/bash
NOW=$(date +"%m-%d-%Y")
for region in $(aws ec2 describe-regions | jq '.[] | .[] | .RegionName' | cut -d\" -f2)
do
    aws ec2 describe-network-acls --region=$region >> aws-all-network-acls-$NOW.txt
done
