for my $key (keys %$hashref)

Use of uninitialized value $_ in concatenation (.) or string at kontakte-utube.pl line 52.
Wie frage ich & perlintro brian's Leitfaden für jedes Perl-Problem
2010-04-07T08:08:14 pqhm, da hat aber einer nicht getestet.
wenn man über die keys einer hashref iterieren will, schreibt man:

alles andere wäre voodoo (woher soll perl wissen, dass du hier die keys willst).
