Drupal - Bash shell script to fix Drupal 8 permissions where the PHP Handler is FastCGI.

fix-drupal8-permissions.sh

#!/bin/bash

path=${1%/}
user=${2}
group=${2}

help="\nHelp: This script is used to fix permissions of a Drupal 8 installation in which the PHP Handler is FastCGI\nYou need to provide the following arguments:\n\t 1) Path to your drupal installation\n\t 2) Username of the user that you want to give files/directories ownership\n\nNote: This script assumes that the group is the same as the username if your PHP is compiled to run as FastCGI. If this is different you need to modify it manually by editing this script or checking out forks on GitHub.\nUsage: bash ${0##*/} drupal_path user_name\n"

New lines "\n" and tabs "\t" in the original script had the \ stripped away. Had to also add \ before ;
It now works for me!

little error in line 29.
