title: Unable to exec() in gulp
body: <p>I want to be able to run this command </p>
  
  <pre><code>exec('devtool bin/www --watch -s');
  </code></pre>
  
  <p>inside of a gulp task</p>
  
  <pre><code>var gulp = require('gulp')
      , exec = require('child_process').exec
      , nodemon = require('gulp-nodemon');
  
  gulp.task('startCmd', function (cb) {
          console.info('running'); //running (aka it runs)
          exec('devtool '+ __dirname +'../../bin/www --watch -s');
  });
  </code></pre>
  
  <p>So why does this cmd not run?</p>
