Hmm you have a point but I don't think it's a problem since this is for the cli instead of the browser. Plus $ is pretty common in the shell to indicate the prompt.

    import { $ as sh } from "bun";

(if you're coming from old school client side javascript I can see the momentary confusion (and in fact I had to blink myself), but in a shell script $ making you think of a shell prompt nonetheless seems like a pretty reasonable default to me)
