# Retrieve EC2 instance type info such as vCPU, clock speed, memory, network
# This queries your default AWS region
# Results are saved to the user-defined file name: $TSV and also to the MacOS clipboard
# Note: the 'RAM in GB' column is rounded to the nearest whole number
# 
# You should use aws cli version 2
# This was created with:
# aws-cli/2.0.36
#
# You must have 'jq' installed from:
# https://stedolan.github.io/jq/
