Re: Context of "if" statements?

The problem IS with the next line. As the split has been skipped, $server, $dir, $type, all three of them are undef, and in the print statement, you are trying to concatenate undef's. This is easy to prove, it will be fine, if you change your print statement to:

print "$server $dir $type\n" if defined($server);

So just put those two lines into one if block.
