you need to provide the following arguments:

1) Path to your Drupal installation.
2) Username of the user that you want to give files/directories ownership.
3) HTTPD group name (defaults to www-data for Apache).

Usage: (sudo) bash ${0##*/} --drupal_path=PATH --drupal_user=USER --httpd_group=GROUP

Example: (sudo) bash ${0##*/} --drupal_path=/usr/local/apache2/htdocs --drupal_user=john --httpd_group=www-data
