Oracle Cloud Infrastructure - Linux Status Script

This script is a customized login banner or dashboard utility specifically designed for an Oracle Cloud Infrastructure (OCI) instance. It is likely intended to be placed in a .bashrc or .bash_profile file to greet a user with hardware specs upon logging in via SSH.

Ensure jq is installed to parse JSON response from metadata service.
