TS + Deno + dax is my favorite scripting environment. (Bun has a similar $ function built in.) For parsing CLI args, I like the builders from Cliffy (https://cliffy.io/) or Commander.js because you get typed options objects and beautiful help output for free.

If you want to script in Rust, xshell (https://docs.rs/xshell/latest/xshell/) is explicitly inspired by dax.
