Maybe. I don't know how to reverse a scalar. I could convert it to an array and reverse that, which is my current (slow) method. My end goal is to avoid having to manipulate this giant scalar as much as possible, and I was hoping with with the proper regex I could extract the data I want with as little handling of the large file as possible.

Sadly, because of the way I'm retrieving this file I can't just read it from the filehandle, it has to be a single scalar, so elegant solutions like File::ReadBackwards don't work in my case either.
