refresh.sh

#!/bin/bash

# This script helps make recovering from Salesforce Refreshes easier. It:
# 1. Updates Heroku env vars
# 2. Clears now-invalid user DBs on Heroku apps
# 3. Updates env vars for CircleCI

# To use this script:
#   1. Put the updated env vars in a file (.env generally)
#   2. If you don't already have it installed, run `brew install jq` to install the jq tool
#   3. Get a circleCI token by going to https://app.circleci.com/settings/user/tokens and adding a personal API token.
#   3. Run the script, passing your environment and circle ci token as arguments
