[OT] perl regex problem

[Hunter Marshall <hmarshall@viasat.com>]

I am a long time debian and perl user. But obviously long enough!
Forgive the slight misuse of the list, but can anyone shed light
on what I'm doing wrong in this attempt to find \n\n in a text file 
with perl? I'm sure I've done this before.

Thanks
