Been working on https://github.com/amterp/rad for almost a year now. It's a programming language designed for writing good CLI scripts, so it's aiming to replace Bash but is much more Python-like, and offers unique syntax and a bunch of in-built support for scripting.
Please check it out if it sounds at all interesting! Keen for feedback :) I've written some docs, including a "getting started" guide, linked in the GitHub page.
