Re: I don't get map. How would I use map here?

Neither realy needs to be a map. However you could make the second one a map like the following:

map { print "$_\t=>$byFile{$_}\n"; } keys %byFile;

map in void context still rankles me for some reason (even though I understand that perl now has an optimization for it). So I'd write that as one of these: `print map { "$_\t=>$byFile{$_}\n" } keys %byFile;` [download] or `print "$_\t=>$byFile{$_}\n" for keys %byFile; # look Ma! no map! :-)` [download] duff	[reply] [d/l] [select]
