Ask me a Unix question on Twitter

Hi everyone, it seems to be really long since my last technical post here – too much stuff happening at work, plus I'm studying for a CCNA exam.

If you're in need of quick help – drop me a message on Twitter – I'm UnixTutorial there. I can't promise a prompt reply, but at least this way you'll have some interactivity.

I see how many people leave questions in comments to my posts, and I don't always have the time to reply – so feel free to send me an email if you really need my help.
