So, the concept is to get a summary of the size of each S3 bucket - almost like the du command on Linux.

The code concept from below is still untested, but I will soon test it and hopefulle have a modified general purpose utility for wider use.

Basic code from stackexchange.com:

#!/bin/bash
aws_profile=('profile1' 'profile2' 'profile3');

#loop AWS profiles

Context

I often need to play and experiment and using different environments help. In the era of virtualisation we have many options. For this exercise, I'm using Ubuntu Multipass which allow you to vey quickly create virtual machines.

The steps described here will not only install the latest version of Node.js but will also setup the environment to install any global packages in ~/.npm-packages.

Starting a new Multipass Ubuntu Instance

$ multipass launch -n nodejs
