Just browsed around through Linux blogs and I came across an interesting tool “htop” posted at Linux and Open Source Blog.

What is htop? It’s an interactive process viewer for Linux. It’s very similar to top, however htop enables you to scroll the list vertically or horizontally; as well as supporting mouse operation.

To install htop on Debian/Ubuntu distros, run this command:

$ sudo apt-get install htop

For openSUSE 10.2, you probably can install it with Yast, but I like smart:

$ sudo smart install htop
