I followed that link, and understand that the awk is reading the filename as a variable declaration.
But I was wondering if there is some way to trick awk into using an expression such as not=working as a filename, as my files have equal signs in the names. I couldn't see that information in the link.
A simple escape character not\=working does not work.
