In general, "exit 1" (newline shouldn't be needed unless the shell is buggy). bash allows a smaller variant: "! :" (again, newline optional).
I've seen somewhere a shell that lets you save an extra byte by using "let 1", but the ones I tested set an exit status of 0 for that (which is arguably more correct). (The shell in question predefined an "alias false='let 1'" IIRC.)
I don't know of any smaller versions. That doesn't mean they don't exist... someone somewhere may have a shell with a :-equivalent which returns a nonzero exit status.
