If you are writing shell scripts that manipulate big amounts of data it is helpful to the person running the script to know what is going on.

The easies way is to just print out a status line every now and then. The problem is when we have a lot of status updates with just a small change we end up with a full screen of status updates but with very little useful data.

For example, we have a list of cities that we are updating and we would like to know how far along are we.

We could print a bunch of lines like this

Updating cities: loaded 10000
Updating cities: loaded 20000
