My question is how do I iterate over the anonymous array?
That is not very hard. Iterating over an array in Perl is done
as follows:
foreach my $element (@array) { ... }
But, where ever we write
@array, we can replace
the
array with a block returning a reference to
an array - which can be anonymous as well.
So, in your case, $fileinfo{$md5hash}{path} is
a reference to an array. Hence, you can iterate over it like:
foreach my $element (@{$fileinfo{$md5hash}{path}}) {
print $element, "\n";
}
