For Unix, if you're not working in Unix environment, you can't say you can learn it well at home, cause you have no chance to pratise the corporate backup, volumn management. What you can do at home is only learn some basic unix commands, like "ls", "cp" and so on, which is far away from the job requirements.
Anyway, good luck my friend! Hope to see you in next year!
