Description of the bug:

I'm trying to execute a shell script from node js file. When I'm executing this script from terminal I'm getting different result from what it returns when executed from nodejs using shelljs

Example ShellJS command to reproduce the error:

var shell = require('shelljs');
shell.exec('./alphanet.sh status', function(code, stdout, stderr) {
  console.log('Exit code:', code);
  console.log('Program output:', stdout);
  console.log('Program stderr:', stderr);
});

here's the link for the script https://github.com/tezos/tezos/blob/alphanet/scripts/alphanet.sh
