Same way you return a string, or a number, or anything else: you don't. Functions in bash aren't actually functions. They're user-definable commands (procedures). Asking how to return a list from a function is exactly like asking how to return a list of filenames from "ls" or "find". > * hashes, lists, but syntax is wired (IMHO) > => can you return lists? Hell, you can't even pass a list IN as a value, let alone RETURN one. > ... -> so for anything complex use a real language, please.
