Create some vhosts domain structure in ruby script

A guide of my own script that creates a directory structure for a new project.
I have my Apache web server set up to look for .conf (configuration files) in certain directory. Which in this case on
/var/www/_conf/enabled.

require "pty"
require "expect"

command line

To use this:

ruby createdomain.rb <yourdomain.com>

For example:

ruby createdomain.rb mdstn.com

That will create:

/var/www/vhosts/
  mdstn.com/
    httpdocs/
    subdomains/

create an Apache configuration in:

/var/www/_conf/available

and a linkage in:

/var/www/_conf/enabled

The enabled directory is where Apache will look for the configurations.

Also this script will prompt if you want to restart the Apache web server.
