Greg -- When you're looking for something in particular, it's easy to just look for that specific thing. As you say, Perl has different definitions of what "\n" actually translates to depending on platform and context. So rather than worry about "\n" just have Perl look for what you're actually looking for. :)
That is, a text file from platform X will have certain line-endings, so you can use the \n approach. For a binary file that's platform-independent, seek out dependable codes instead. E.g. $string =~ /([^\012]+)[\012]([^\012]*)/; Finds everything up to the first \012 and stuffs that into $1, then the \012, then everything (including nothing) after that first \012 gets stuffed into $2. Of course, this is Perl, so TMTOWTDI<http://en.wikipedia.org/wiki/There's_more_than_one_way_to_do_it> . Savvy?
