"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.

top command wills how you how many cpu you got
there is another one

i will give you the name 5 min
cat /proc/cpuinfo | grep processor | awk '{count++} END {print count}'

This will give the CPU count but it will list dual core type processors as '2' as that is sort of what they are inside.
