Hello `wc -q` is listed as a rejected feature request [1] because "redirecting file to stdin is sufficient". However, I don't think this is sufficient because it only works when handling a single file.
A feature request in the mailing list after the above [2], suggests to me that the feature was thought about. I don't mind sending a patch that implements it, but please let me know if I should bother. Many thanks David [1] https://www.gnu.org/software/coreutils/rejected_requests.html#wc [2] https://lists.gnu.org/archive/html/coreutils/2015-11/msg00066.html
