Find memory consumed by currently running processes on Linux?

I always had the question (when I am running plenty of scripts on a linux box as to what is eating up all the memory? Finding memory consumed by current running processes in your favorite linux distro. Luckily, I found a great Python utility (scriplet to be exact).

First download the script

wget http://www.pixelbeat.org/scripts/ps_mem.py

Chmod it to be executed from command line

chmod +x ./ps_mem.py

Then run this script from shell (Putty / SSH)

./ps_mem.py

The output will be similar to the one below (this output is from Ubuntu Server)
