Re^3: How do I recursively process files through directories

[Aristotle]

You have to put them where you want them. In your example that would be

my @stuff;

sub wanted {
    push @stuff, $File::Find::name
        if -f && ! -d && m/\.mp3$/i;
}

find(\&wanted, $mp3_dir);

or better

my @stuff;

find(sub {
    push @stuff, $File::Find::name
        if -f && ! -d && m/\.mp3$/i;
}, $mp3_dir);

Except it isn't better, since all you're doing is to process them one by one. So do it right in the callback function:

find(\&wanted, $mp3_dir);
                                                                      
+          
sub wanted {
    return unless -f && ! -d && m/\.mp3$/i;

    print "$File::Find::name\n"

    my $mp3 = MP3::Mplib->new($item);
    my $v1tag = $mp3->get_v1tag;
    my $v2tag = $mp3->get_v2tag;
                                                                      
+          
    while (my ($key, $val) = each %$v1tag) {
        print "$key\: $val\n";
    }
    while (my ($key, $val) = each %$v2tag) {
        print "$key\: $val\n";
    }
}

Update: That should be push @stuff, $File::Find::name, not push @stuff, $_, otherwise you loose the path.

Thanks for the post. The first suggestion actually worked well. I want to do a lot more here (as you might be able to imagine) than just print the MP3 ID(v1|v2) tags. So it is *handy* to have the entire file list available as an entity.

Thanks, again.
