This leads to possibly ugly output as there will be an extra comma in the output Also will a value appear more than once, and should the values be sorted as well? Im thinking a HoH might be overkill, but another (better?) way to do it. `my %all; while (<>) { s/\s+//g; my($k, $v) = split /,/; next unless defined $k and defined $v; $all{$k}{$v}++; } for ( sort keys %all ) { print "$_, ", join(', ', sort keys %{ $all{$_} }), "\n"; }` [download] use perl;	[reply] [d/l]
