Re: Parsing text file into a hash with multiple values per key

in reply to Parsing text file into a hash with multiple values per key

how do I remove duplicates (Host and VM)?

There are no duplicate hosts (hash takes care of that), so to get rid of duplicate VM, use another hash, a hash of hashes, ie  $HostVM{$host}{$VM}++

how do I then count the # of values per key?

For your existing code  my $count = @{ $hash{ $host } };

For my code  my $count = keys %{ $hash{$host}{$vms} };
