How to upgrade via CLI

Hello,

We are in the process of migrating to AWS.

We will be using Hashicorp's Packer and Terraform to manage the entire process for us so I am needing to acheive everything from the CLI so the images can be placed in to the Auto Scaling Group.

We are using the CF2016 AMI on Ubuntu that is available in the market place. We have automated the installation (not a full install but can't remember it's name) but I need to have to boxes upgrade to the latest version of Coldfusion. I can obviously acheive this through the admin interface but I can not seem to find anywhere how to do thing from my Bash scripts.

Has any one else run in to this or solved it?

Thanks
