From https://unix.stackexchange.com/a/94200/674If there are no positional parameters ($# is 0), then $@ expands to nothing (not an empty string, but a list with 0 elements)So how differently do an empty string and a list with 0 elements behave?Does a list with 0 elements mean an array with 0 elements? I don't see bash has the concept of list.Can nothing mean something which is not necessarily a list or array?
