I love writing little tools and scripts that use pipes, I've accumulated a lot of them over the years and some are daily drivers.
It's a great learning tool for learning a new programming language as well as the interface between the boundaries of the program are very simple.
For example I wrote this recently https://github.com/djhworld/zipit - I'm fully aware you could probably whip up some awk script to do the same, or chain some existing commands together, or someone else has written the same thing, but I've enjoyed the process of writing it and it's something to throw in the tool box - even if it's just for me!
