There are many solutions to this problem, but which ones are best will depend on how you are displaying the information.

If you're doing a web page, what you should do is fork off processes and background them, then return a web page and have ajax requests return and poll for the data. (It is up to you to figure out a way to communicate between the forked processes and the web page.)

If you're doing a GUI you can use a similar approach with polling for data. Alternately you can explore the world of asynchronous programming. Which will lead you to modules like POE. Or you can explore the complications of multi-threaded programming (which in this case is going to be similar to the fork approach, except that you've got threads rather than programs).

If you've got a command line or a batch program, treat it like the GUI.
