Using an unquoted string with ! -z, or even just the unquoted string alone within test bracket normally works, however, this is an unsafe practice. Always quote a tested string." And indeed: $ unset FOOBAR $ [ -n $FOOBAR ] || echo nope $ [ -n "$FOOBAR" ] || echo nope nope Ran into this on a box w/o the attr program installed, and passed _require_attrs. Quoting the string fixes this; fix it there and other occurrences in common/* as well.
