How to detect if command run terminates

[dgramop]

Hi!
Just curious as to how I would detect if the command terminates. I tried setting the exec to a variable and doing variable.on(....) as I would to a normal async child process.

Is there any way I can do that?

Does this run the command asynchronously?

Thanks @BrainyBrian

To confirm, your command will be run asynchronously in another process.

Your callback will be called as soon as your command terminates:

sudo.exec('echo hello', options,
  function(error, stdout, stderr) {
    console.log('command terminated');
  }
);

sudo-prompt exec() is different to that of child-process since it needs to deal with permissions issues on different platforms. It does not return a child process instance.
