...also you should be:
1) Using the three arg form of open().
2) You should NOT be using a bareword filehandle.
This is the modern way to open a file:
open my $F1, '<', $file1
or die "Cannot open file $file1 \n";
while (my $line = <$F1>) {
...
}
And this:
while (defined(my $f1 = <F1>) && defined(my $f2 = <F2>)) {
...
}
should be more like:
while (
defined(my $line1 = <$F1>)
and defined(my $line2 = <$F2>)
)
{
...
}
