Yep, this works really well, so I will be able to start coding. Thanks to everyone that offered suggestions. I didn't want to use an external program unless there was no other way. I'll post a snippet when I have something finished.
There is a small typo though -

for my $f (@interfaces) {
[download]

should be:

for my $if (@interfaces) {
[download]

otherwise nothing prints out..
