It's also worth pointing out that you haven't created a multidimensional array.
Therefore,
$url_info[$index][0] won't give you what you want.
While we're at it, go ahead and print out the error code if
the open() fails.
Try reading the INPUT filehandle like this:
open(INPUT, '< graduate.output.txt')
or die "Couldn't open the file for reading: $!";
while(<INPUT>) {
chomp;
my $@a = split /,/;
push(@url_info, \@a);
}
close(INPUT);
