Thank you very much for this script! I would like to ask for some possible modifications. - I am not familiar with the open structure in this script. I would like to convert it to a familiar one (open(FILE1, "$ARGV[0]") etc.) but I could not do it. I tried the following: 
my $data1 = $ARGV[0];
my $data2 = $ARGV[1];
my $data3 = $ARGV[2];

- Second, I failed at printing out once again. I used this one: print Data::Dumper->Dump([\%data],['MERGED HASH']),"\n"; How can I print the merged hash into an output file? I though of, again, the familiar structure, but it did not work. 
open(FILE3, ">$ARGV[2]");

{print Data::Dumper->Dump([\%data],['MERGED HASH']),"\n";}

Is it the reference again?
