Node version (or tell us if you're using electron or some other framework):

6.x.x

ShellJS version (the most recent version/Github branch you see the bug on):

Newest

Operating system:

Ubuntu 16.04 Linux 64 bit

Description of the bug:

No bug...just a question.

Example ShellJS command to reproduce the error:

shell.exec('rsync -avP ' + inputPath1 + ' ' + inputPath2, function(code, stdout, stderr){
    console.log(code);
    console.log(stdout);
    console.log(stderr);
});

I know this is running, I can see it in the terminal, but I want to give feedback through the GUI that it's running. Is there some way to know it's running. I don't see any feedback in the console until the entire operation is complete, and depending on the size of a directory this could take a while.
