most /env things haven't got newlines so wc -l /env/* generally gives 0.you also need to watch the binding in things like this:
ie, the env file might be created in the parent name space, because the > is done before the @,
and in the scope above the rfork e, compared to
term% @{rfork e; echo hi >/env/hi}
term% ls /env/hi
ls: /env/hi: '/env/hi' file does not exist
