>From perlop:
In scalar context, evaluating a filehandle in angle brackets yields
the next line from that file (the newline, if any, included), or
"undef" at end-of-file or on error. When "$/" is set to "undef"
(sometimes known as file-slurp mode) and the file is empty, it returns
"''" the first time, followed by "undef" subsequently.
so something like
$lines = <INFO> or last;
should do the trick. That will stop the loop at end of file.
