heroku-export.js

/** 
  steps: (for ubuntu. most shells should be similar)
  
  1) install heroku cli (eg, `npm i -g heroku`) 
  2) log in (`heroku login`)
  3) list apps: `heroku apps > apps.txt`
  4) run this script: `node heroku-export.js | bash`
  
  you may want to run step 4 and verify the commands before piping it into bash
