This page describes various GNU/Linux commands and shows the BSD equivelant commands. I am writing this because one of my biggest problems in switching to BSD was learning how to do the same thing that I already new how to do in Linux.
Note: At the moment, this is just a very rough draft. I plan to add much more detail later, but I do not have the time right now. there may also be errors in the BSD commands, particulaly NetBSD and OpenBSD as I am much less familiar with them. Any suggestions, patches, critiques are welcome.
