Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

You didn't say what system you are on, but those using SELinux recognize the difference between the real UID and effective UID. For normal DAC access, the effective UID is sufficient. But with SELinux active you also have to have the appropriate security label.
...and you're stuck because you're not trying to VIEW that file, you're trying to EXECUTE IT. It's a text file, not a program. Try running "cat /etc/resolv.conf", to display it to the screen, or "<whatever editor you want> /etc/resolv.conf" to edit the file.
Be aware that if you don't know how to view a text file, you probably shouldn't be editing system files, unless you are SURE you have backups, and are SURE of what you're doing.
TB0ne, thank you. What I have pasted here is from the command I ran. ..and yes, I want to edit the text file so how do I find my way there? I actually did "/etc/resolv.conf" as you put it but its not displaying the content....cat /etc/resolv.conf only gives me the nameserver, that is not what I want. I want the text file so that I be able to edit it. Yes I have been authorized to so.
