This approach also counts hidden files while the original did not include those in the count. That said, to avoid the inefficiency of searching the subtrees, all you had to do was reverse -type and -maxdepth: find . -maxdepth 1 -type f | wc -l And this should be more efficient than descending into each subtree and then pruning it as your first action.
