in reply to File Locking

Hmm... Seems like you have empty @friends there. The loop should probably be something like:
while(<MYFILE>) { if (m/^$newfriend$/) { print "You are already on the list!\n"; exit; } push @friends, $_; }
...or one could of course concatenate to the file.

[choroba]: Perl to the rescue!
[Corion]: hippo: At least for the German translation, the wordplay is translated as well
[Discipulus]: always! but if i can ask choroba why you always use the inverted (to me) form 1 == $.?
[choroba]: To avoid accidental overwriting of the variable in if ($x = 3)
[karlgoethebier]: Corion: Auch in hessisch? Mer wasses net.
[Corion]: Hmm - I'm not sure, I haven't read the mundart/slang translations ;)
[Eily]: $F[1] =~ s/^0//r could be written as (0+$F[1]). It's less explicit though
