I am a huge fan of using `make` for this sort of ad hoc data pipeline. The workflow is very natural, as you can play around with each step on the command line and then drop it into the makefile once you get it right..better for reproducibility than search up through terminal history to replay individual lines!

In your example, I would drop the shell and python scripts and simply run:

    watch -n 2 -d "touch a && make"
