Exports Terraform outputs into an environment file that can be sourced into shell

export.sh

# Exports Terraform outputs into an environment file that can be sourced into shell
# Supports Terraform 0.12+ (also works with Terragrunt 19+)
#
# It can be useful to export tf outputs into a .env file for use with serverless, jenkins, and node
# to use with tools that directly support dotenv, remove the "export " from the prefix
#
# Steps
# 1. Gets the terraform output
# 2. Add quotes to the right hand side of equals
# 3. Remove spaces around equal signs
# 4. Add a prefix for the env variables
# 5. Output to a dotenv file that can be loaded with source command or dotenv tools
