title: Interview question: Are you familiar with linux?
body: <p>I've ran into this question a couple times where people ask me if I am familiar with linux.  What does this usually imply?  I know how to navigate a command prompt in Ubuntu, edit files, compile c programs, but I feel like I am only scratching the surface.  Any tips on how one becomes a guru in linux?  Thanks for any advice.  Hope this question isn't too subjective. </p>
