I see where you're creating hash: 
$hash{$vars[2]} = join(' ', @vars[0,1,3]);

How would I print that out? 
foreach $var2 (keys %hash){
  print "value: $hash{$var2}\n";
}

...doesn't work too well.

    What do you mean "doesn't work too well"? That should work.
    Is an error occuring, is there not output, or is it not the way you want it to look?

      It's not printing unique values. However, it is printing "key ' ' already exists in hash" after each line.

      So basically it's printing all the rows even those with $var2 that aren't unique.
