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.

None of the lines you posted has 8 fields, so the first
Code:
awk '{print $8}'
prints nothing. I would not use a similar chain of grep and multiple awk processes. You can do it all with a single call to awk. Please, post an example of the desired output, based on the input above, and we could give some better advice.

Reason: script corrected
you can modify { exit 1 } to print a message also if you want to do so:
{ print "THIS IS AN ERROR" > "/dev/stderr"; exit 1 }
