[+]mysqlnd
percona
php54-mysql has the variants

I have only rudimentary acquaintance with sed and less with awk. I'd
like to learn more and this seemed like an opportunity to do so.
From some reading [1], I think sed's Hold buffer is the way to
extract the port name and insert it onto the line with each of the
variants. But the tutorial only uses the hold buffer for full lines;
not just, say, the first word of the line. Is this possible? How
does one do that?

Or maybe I'm barking up the wrong tree? Is there another
tool/technique that is better suited?
Thanks in advance,
Craig
