Yes, though it's a hack with some potential issues: like the error messages from "sh", if any will look like: ../this/dir: error... instead of: sh: error... > and then > > find . -type d -exec test -e '{}/file' \; -prune -o ... no, won't work with many "find"s and is not standard. {} has to be an argument to find on its own for it to be portably recognised by find. > You may also use > > find . -type d -exec [ -e '{}/file' ] \; -prune -o ...
