 It is roughly equivalent to the following one-liner (included as `dups.sh`):
 ```sh
-find . -type f -print0 | xargs -0 -P 6 -I % md5sum % | awk '{digest = $1;  sub("^" $1 " +", ""); path = $0; paths[digest, ++cnt[digest]] = path} END {for (digest in cnt) {n = cnt[digest]; if (n > 1) {print(digest, n); for (i=1; i<=n; i++) {printf "    %s\n", paths[digest, i]} } } }'
+find . -type f -print0 | xargs -0 -P $(nproc) -I % md5sum % | awk '{digest = $1;  sub("^" $1 " +", ""); path = $0; paths[digest, ++cnt[digest]] = path} END {for (digest in cnt) {n = cnt[digest]; if (n > 1) {print(digest, n); for (i=1; i<=n; i++) {printf "    %s\n", paths[digest, i]} } } }'
