a decade ago i probably would have done the same thing; i've since ditched perl
in favor of python and rarely think about perl now. i was shooting for something
that would mostly "just work" no matter where i tried it, so i figured i'd need
to use the base tools (awk/sed/whatever). but this solution definitely
worked across all the platforms i tested it on, as perl was already installed.
i suppose perl might be just about everywhere by default - and if that turns out
to be the case, this is a great solution.

thanks!
