Running `lsof -i` (with no arguments to -i) "selects the listing of all Internet and x.25 (HP-UX) network files." I'm looking for a reliable way to do the inverse: show a listing of everything EXCEPT Internet files. By reliable, I mean a way that would only require lsof to be run *once*. Two subsequent runs (i.e., a normal `lsof` followed by a `lsof -i` in order to compare) is not reliable because of the strong possibility of churn.

Thanks in advance!
