title: Running a shell command from gulp
body: <p>I would like to run a shell command from gulp, using <code>gulp-shell</code>. I see the following idiom being used the gulpfile.</p>
  
  <p>Is this the idiomatic way to run a command from a gulp task?</p>
  
  <pre><code>var cmd = 'ls';
  gulp.src('', {read: false})
      .pipe(shell(cmd, {quiet: true}))
      .on('error', function (err) {
         gutil.log(err);
  });
  </code></pre>
