Nodejs: Childprocess exec kill is not a function

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I'm trying to kill a childprocess opened with exec. I can't use spawn since then, the childprocess doesn't seem to work.

Am I missing something? Are childprocesses unkillable?

Thanks in advance

*EDIT: Code

    const child = exec(

     __dirname +

     "/ffmpeg/bin/ffmpeg -i " + url + " -acodec copy -vcodec copy " + savePath,

     function(error, stdout, stderr) {

      console.log("stdout: " + stdout);

      console.log("stderr: " + stderr);

      if (error !== null) {

        console.log("exec error: " + error);

      }

    }

  );

How are you trying to kill the process ?

exec opens up a shell to execute the command you pass. Some programs may end up being run independent of the shell. Why are you not using spawn?

@TGrif: I tried to use the process.kill() and process.stdin.write("q") (which should close the command) but both don't work.
