Whenever I run a screen session I always used to have top running in screen 0 by default.
This was till recently when a friend recommended `htop` to me which is a great enhancement on top and I now use this by default.
Just the other day I found another alternative to using `top` which is `nmon` although its not as customisable as `htop` it still has some good features, so I thought I would do a quick post on both and also share my configs which I think work well.
