part of the code:

(new CronJob('0 0 */4 * * *', async function() {
  console.log('[every 4 hours] Job fired:', new Date() );

	await exec(` kill -9 $(jobs -p) ; time ./someScript.js --timeframe 240 `, (error, stdout, stderr) => {
		if ( error ){ console.log(error) }
		if ( stdout ){ console.log(stdout) }
		if ( stderr ){ console.log(stderr) }
	});

  // console.log('Job Completed:', new Date() );
})).start() ;
