Create a new vHost in Ubuntu Server
Assumes /etc/apache2/sites-available and /etc/apache2/sites-enabled setup used

    -d    DocumentRoot - i.e. /var/www/yoursite
    -h    Help - Show this menu.
    -s    ServerName - i.e. example.com or sub.example.com
    -a    ServerAlias - i.e. *.example.com or another domain altogether
    -p    File path to the SSL certificate. Directories only, no file name.
          If using an SSL Certificate, also creates a port :443 vhost as well.
          This *ASSUMES* a .crt and a .key file exists
            at file path /provided-file-path/your-server-or-cert-name.[crt|key].
          Otherwise you can except Apache errors when you reload Apache.
          Ensure Apache's mod_ssl is enabled via "sudo a2enmod ssl".
    -c    Certificate filename. "xip.io" becomes "xip.io.key" and "xip.io.crt".

    Example Usage. Serve files from /var/www/xip.io at http(s)://192.168.33.10.xip.io
                   using ssl files from /etc/ssl/xip.io/xip.io.[key|crt]
    sudo vhost -d /var/www/xip.io -s 192.168.33.10.xip.io -p /etc/ssl/xip.io -c xip.io

Updated, ty

Could you by any chances add ServerAlias as a option? That way in Vaprobash could add the ability to use the Vhost config option and the xip.io option as well.

yes this script misses out a very important step which is to add the server alias to the /etc/hosts file

echo ${Alias} >> /etc/hosts

add this line to the end of the script (before the last 'fi')

this is for ubuntu

sorry i meant add this:

echo 127.0.1.1 ${Alias} >> /etc/hosts

This rocks. In order to add the localhost information to the beginning of /etc/hosts, add this instead:

                    echo 127.0.0.1 ${Alias} | cat - /etc/hosts > /tmp/out && mv /tmp/out /etc/hosts

This generates a file with the new localhost information added to the top. Great scripts.
