When you're copying a file on a network share for example, it tends to be slow, you'd sometimes like to know where you are.
Well even if the basic idea is just to monitor the speed of writing to a pipe in shell, you can actually use it to copy a file and monitor it's progress. It's quite nice and will avoid me to start Midnight Commander just to be able to see the speed of a copy.
