What paradigm to use when determining shell script vs a "proper" programming language?
I made a fairly significant edit to remove the "which language should I pick?" part of this question and focus on the core question.
Understanding how to decide when to move away from bash scripts is a question I think most programmers face and one where I believe there is a good, systematic approach towards understanding.
This got mod-clobbered right around when I edited it, for good reason, but this did not reflect the substantial edit I made.
