Can't figure out how to run command only once inside Nodejs nested callbacks

I'm executing a child_process exec command, and it will be running several times, but I want to be able to then run a function ONLY AFTER all of the child_process iterations have finished. Is there a way to do this without libraries and just with callbacks? Right now, I can call it inside the child_process.exec body, but then the inner function would execute multiple times....child_process.exec('some command', function(err, data) {// run someCommand() after child_process.exec finishes // But ONLY once});
