The line: 
    print (OUTFILE);

[download]

prints $_ to the filehandle. But what is $_? It's set by the while loop, so it has the value of the last time the while was checked. Which was at the end of the file, and hence $_ is undefined.

That's why you get your warning, and that's why the file is empty - undef stringified gives you the empty string.
