@jredville the reason I only mention vi is because I'm yet to see a unix box where it's not there. The same does not apply to other editors, so that's why I believe it's essential to know the minimum of vi in case you get to a machine without install privileges.

tmux - I think you should add this as well. It's so very handy when working on multiple servers and multiple tasks.
