As an alternative to (npm -g)'ing here some potentially useful coreutils one-liners I've been using for a similar purpose:

- Dump all .py files into out.txt (for copy/paste into a LLM)

> find . -name "*.py" -exec cat {} + > out.txt

- Sort all .py files by number of lines

> find . -name '*.py' -exec wc -l {} + | sort -n
