Is it possible to use
find to only return a result is 3 file names are present in that directory?
of course at the end we can use
wc -l to tally them up...
but starting with some sort of a project root directory and then within just those subfolders that match name / regex pattern try to list ones that have within them:
and then only count the directly with
wc -l if all those files are present within it?
