I thought I had done something right because it was working, then I looked at the code and realized it wasn't supposed to be working. I'm actually glad, but a bit bewildered!
# all my tmp dirs
@dirs = GetDirs('/tmp');
print "@dirs\n";

sub GetDirs {
    
    my $startdir = $_[0];
    
    foreach $leaf (glob("$startdir/*")) {
        if (-d $leaf) {
            @dirs = GetDirs($leaf);
            push(@dirs,$leaf);
        }
    }
    
    return (@dirs);
}

If at every $leaf I am re-defining @dirs (since it isn't my @dirs), how can it return all of my sub-dirs? Shouldn't it return only the last directories in my last leaf?
I'm happy, but a bit confused...

Anyone care to enlighten?
