Ask HN: Show me all the shell code you've over engineered

I wanted to make this post because a few years ago I was running a very low powered laptop and wanted to cut some time off searching Google and YouTube for things. So I wrote [this script](https://github.com/0x3444ac53/ellies-bash-scripts/blob/master/modules/search.sh) that can search a variety of sites for a string. It has support for the encyclopedia of philosophy and will let you select the article you want and output it as a PDF file.

Anyone have anything similarly over engineered for a specific use?
