Unix certification

Hi,

I'm working with Unix about 2 years now. and I'm wondering if there is any kind of certification program what is reconized by company's.
The only certification program that I know is from The Open Group.

You can read this thread for some info about which certification you might find useful. Remember that each vendor provides their own certification, so you can go to, say, hp.com or sun.com and search for 'certification'.
