How To Install

1. Upload the script to /root/bin directory and rename it to nvhost
2. Set the script as executable. chmod +x nvhost
3. Add your file to PATH
4. Now you can just type nvhost in your terminal ( with root excess (sudo) ).

The script will ask for domain name to input. Once you give it it will do the rest and create the vhost for you.

Enjoy! :)
