I want to add new user and have/grant that new user to have all the root access, how can I do that ?

First, create a normal user account.
Then select one of the following:
The Right Way
Or for "modern" versions:
Then add the user to the
Note that some distributions use different administrative accounts. Wheel is a "traditional" approach to this, but you may encounter

Create a sudo entry for the user account in question and give then complete access. Again, you create the entry in

You may study the way suid (http://en.wikipedia.org/wiki/Setuid) works if you want to grant him root access for just a few of the commands.
