Anonymous Monk:

What am i doing wrong?
  1. When you're calling Dumper, you're giving it a hash as an argument. The hash expands to a list of key/value pairs, and each of those is being printed as a separate value. You want to pass it a reference to the hash, like:
    print Dumper(\%hash);

  2. You should put your print statement after the end of your loop. As it is now, you're printing the hash after adding each line to it, so you're getting far more output than you really want. (Unless, of course, you're really wanting to see the hash after each line is added.)
  3. If you're on a windows box, then chomp may not be removing all the whitespace at the end of the line. I generally avoid chomp and use something like:
     $line =~ s/\s+$//; # trim whitespace

If you're still not getting output, you may want to add: 

print "<$fields[0]>\n";

in the loop where you're searching for, so you can see what key is being looked for, and compare that against the keys displayed by Dumper previously.
