"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

echo QUAD | awk -F\. ' (NF == 4  { print $1"\n"$2"\n"$3"\n"$4"\n" } '

NF is the equal to the number of elements. If there are not the four octets, there will be no output.

. ' " , etc. have to be escaped (\) when those are the delimeter.
Do you have to use awk?

If not, easier to do
