I came across this article that describes a few open source productivity/system-monitoring terminal applications. I thought they may be useful to some of us who love to use Terminal for Linux, Unix, or OSX.

I haven’t tried any of them myself but maybe those who do or have in the past can shed some light on them and share their thoughts.
