I see bash scripts that are 1000’s of line of code at work and its a maintenance nightmare.

Knowing when to make the move from “handy bash script” to “this is a production application” and needs to be python is what I see people miss.

After a certain point in complexity the python code wins on maintenance.
Personally i set a low bar to move from bash to python.
