You should be able to get similar results with
$ cd /usr/share/games/fortune
$ awk 'BEGIN{RS="\n%\n"} {f=FILENAME ":#" FNR; if ($0 in a) {print f "="
a[$0];print} else a[$0]=f}' fortunes fortunes2 # ...
which just does an equality-check rather than checking cryptographic
hashes (and requiring disk-space for the temporary files). It emits
record-numbers rather than line-numbers, but if you use vim/neovim[1],
you should be able to do
1953/^%$
to land at record 1953.

would have expected
