I always get asked how I know the things that I know in the UNIX/Linux world, and my reply is a very common one: RTFM. It has somewhat become a misnomer, or perhaps seen as brute way to send off newcomers to the UNIX world, but I think that this is misleading. There is an argument that it is more efficient to use a GUI browser to find the same information, and this is where I usually attempt to make my claim.
