Recently I've been reading up some, and in certain communities Linux and particularly Unix are very well accepted. I want to switch over to Linux or Unix or possibly have both on my system. Any suggestions on which versions to run? So far, I think I may settle on Red Hat because some of my friends have a copy of it, but have no idea on how to use it. Also, Im quite certain that I will have to read up a lot of material to use Linux effectively. Any ideas on which books I should buy?
