bash script to create virtual host vhost with apache2 and Ubuntu

vhost.sh

#!/bin/bash
# This script was originally used for create virtual hosts on CentOs.
# Created by alexnogard from http://alexnogard.com
# Improved by mattmezza from http://you.canmakethat.com
# Adapted for Apache2 on Ubuntu by Stephen Downes at https://www.downes.ca
# Feel free to modify it
#   PARAMETERS
#
# $usr          - User
# $dir          - directory of web files
# $servn        - webserver address without www.
# $cname        - cname of webserver
# EXAMPLE
# Web directory = /var/www/
# ServerName    = domain.com
# cname            = devel
#
#
# Check if you execute the script as root user
#
# This will check if directory already exist then create it with path : /directory/you/choose/domain.com
# Set the ownership, permissions and create a test index.php file
# Create a vhost file domain in your /etc/httpd/conf.d/ directory.
# And add the new vhost to the hosts.
#
#
