Welcome to Linux. The best way I can recommend is to get a (redundant/second hand) PC (at home if possible) and ... install CentOS on it. Configure it as a server and play with it. Link it in a network, try your hand at the firewall, telnetting, remote admin, web server, ftp server, anyhting you can get your hands on...
Bottom line: CentOS is ... Linux. So, if you know the console commands (found on several sites
) you'll be fine. The GUI (the icons, the mouse and stuff) really is secondary to that. Linux is not the pretty desktop, but the stuff underneath, the stuff that manifests itself as ... text.
This line does encourage me:
i have learnt the commands and all and now what step should i be taking?
...so, what you're saying is: "I know how to fine-tune the Lambo's engine, what's next...the paint job?
