Wow, thank you so much Radoulov!

That AWK code is just beautiful, and it works perfectly.

The only minor issue is that not all the blocks of text are separated by the same number of new lines.

Sometime $newpage is preceded (or followed) by different numbers of newlines. In those cases, the code does not delete the duplicate block.

But I can clean up the texts beforehand with some regex.

I will to study your code, to improve my tiny awk skills.

Thank you so much once again.
