My coworker introduced me to htop today ( http://teom.wordpress.com/2012/05/04/color-your-shell/ ). htop is like top, a command line tool to explore processes, but it’s much more cool. It’s got Mouse integration, Kill process menu, Bar graphs for the processors, memory and swap. It’s overall a slick console based app that works great over ssh too!
You can see in my screen shots (htop above, and top below) the differences between the two. I’m really liking htop now.
