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.

pass -f to the shell (for csh or tcsh)

Just a few links to aid you to gaining some understanding;
thanks for the reply I made a mistake by chown from root to admin on /etc/* . this caused it to happen I changed the owner back to root via disc boot and rescue, but that made no diffrence. I was able to sudo but I did not want the hassle of sorting it all out so I upgraded to 12 from 11 and it now works fine, I used my backup drives to back the data up first.
