> For some people a one-hundred-line shell script is too long. For others, that’s a regular day. But most people would probably agree that a 10,000 line shell script should probably have been written in a more robust programming language. So why the contention?

I mean maybe. My big thing is single responsibility.

My suspicion is if you wrote 10,000 lines of shell script that should probably be like 20+ individual scripts and you've written something with way too many responsibilities.

A script should do a single thing.
