Running a shell command from gulp

gulp-shell has been blacklisted. You should use gulp-exec instead, which has also a better documentation.

For your case it actually states:

Note: If you just want to run a command, just run the command, don’t use this plugin:

var exec = require('child_process').exec;

gulp.task('task', function (cb) {
  exec('ping localhost', function (err, stdout, stderr) {
    console.log(stdout);
    console.log(stderr);
    cb(err);
  });
})
