Download and install drupal using drush (by no means should this be used in an unsafe environment)

cdrupal.sh

#!/bin/bash

drupal_version=$1
site_name=$2
db_user=$3
db_pass=$4
db_name=$5

function print_usage() {
	echo -e "Usage: $0 drupal_version site_name db_user db_pass db_name"
}

if [[ ( $1 == "--help") ||  ( $1 == "-h" )  ]]; then
	print_usage
	exit 0
elif [[ "$#" -eq 0 ]]; then
	print_usage
	exit 1 
fi

#cd /var/www/$contextRoot/web

drupal=drupal-${drupal_version}

echo "Downloading ${drupal}..."
drush dl $drupal


echo "Changing drupal folder to the site name: ${site_name}"
sudo mv $drupal $site_name

echo "Entering $site_name folder..."
cd $site_name

echo "Installing drupal..."
drush -y site-install standard --account-name=admin --account-pass=admin \
