Im trying to run this program and they say I should not run it as root but as a diff user. My question is how to change from root to dif. user. I am using linux CentOS 5.5.
Is it a terminal command? How do i create a diff user and log in as it? Thanks!

Depending on the distribution, either `adduser` or `useradd` will be the command to create a user. To switch to another user, use `su`.

Read the man pages for both before using them.

what main pages?

I would recommend to read a beginners guide on linux, before going further. May this one: Getting started with Linux

man pages, i.e. "Manual Pages", otherwise known as "Help Documentation", is the first place to always look when you want to know how a command works, how to use it, or what it does. If you wanted to know about the `su` command, then open a terminal or console window or use a "Virtual Terminal" on your Linux machine, and at the prompt, enter:
Meanwhile, I agree with the above poster - you should start at the beginning, and read some beginner docs about getting familiar with the basics of using Linux. I didn't read the link given by TobiSGD above, but it sounds like it'd be a fine place to start.

Cheers!
