  return exec('ls build') // terminal => 'bar'
})
.then(function () {
  // mute stdout by passing truthy second argument
  return exec('cat build/bar', true) // terminal => nothing

i hate execSync:

// simple deploy
co(function *() {
  yield exec('gulp build')
  yield exec('rsync -rptv --delete server user@host:project')
  yield exec('ssh user@host "cd project; pm2 startOrRestart app.json"')
})
