Where should I start?

Hi All,
I'm working for a software consultancy ,where I'm working on Oracle. But I'm more interested towards open systems. I would like to start with Unix.
I know Unix to some extent, but unable to understand where to start. :confused:
Please suggest me where I can get very good material, and where I should basically start from.
I feel great if any of you could help me in getting to know and of course to master any s/w language/tool/os one should have good practice on the same.
So, please let know where I should start from?

Regards
RK

From the FAQ section: Unix & Programming tutorials

This might not be exactly what you're looking for but honestly it's what got me started down the *NIX road.

Grab an free *NIX OS and start playing around :slight_smile:
Have fun,
