Just paste the shell command you want to run in the first parameter, it can take both absoule path and relative path.

Note that the current working directory will stay unchange after the function is called

var execout = require('execout').execout;

// calling a system shell command
execout("ls");

execout("ls -la", function(err, output, retcode)
{
	if(err) {
		console.log("stderr length: " + output.length);
		return;
	}
	
	console.log("Done. The command print " + output.length + "characters, and return code " + retcode);
});

// execute a binary file using relative path
execout('./node_module/.bin/mocha test --color --recursive');

The first one is err (if have one), the second one is the content was printed on stdout (or stderr if there is error), the last one is the return code of the command.
