Hi, I have two files FILE-1 & FILE-2 in given format.

FILE-1

CLAYCOUNTY;Wood;statecode=FL
CLAYCOUNTY;Wood;statecode=FL
SUWANNEECOUNTY;Wood;statecode=FL
SUWANNEECOUNTY;Wood;statecode=TX
SUWANNEECOUNTY;Wood;statecode=TX
SUWANNEECOUNTY;Wood;statecode=TX
NASSAUCOUNTY;Wood;statecode=UT

Step 1: Parse file FILE-1 with search key "Wood" and store the file columns into hash. I want to use 2nd and 3rd column and put it into a hash. with the 2nd column being the keys and 1st column being the distinct values.

e.g. for Key "Wood" values are
CLAYCOUNTY,
SUWANNEECOUNTY,
NASSAUCOUNTY

open (my $fh, "<", $file) or die "Can't open the file $file: ";

while (<$fh>)
{
    my $line = $_ if /\bWood\b/;
    chomp ($line);
    last if !$line;

    %hash2 = (%hash2 , (split(/;/, $line)),[1,0]);
}
print Dumper \%hash2;

FILE-2 Format as below

119736;Residential;CLAYCOUNTY
448094;Residential;CLAYCOUNTY
206893;Residential;CLAYCOUNTY
333743;Residential;CLAYCOUNTY
172534;Residential;CLAYCOUNTY
785275;Residential;CLAYCOUNTY
995932;Residential;CLAYCOUNTY
223488;Residential;CLAYCOUNTY
433512;Residential;CLAYCOUNTY
640802;Residential;SUWANNEECOUNTY
403866;Residential;SUWANNEECOUNTY
828788;Residential;SUWANNEECOUNTY
751490;Residential;SUWANNEECOUNTY
972562;Residential;SUWANNEECOUNTY
367541;Residential;SUWANNEECOUNTY
481360;Residential;SUWANNEECOUNTY
920232;Residential;NASSAUCOUNTY
727659;Residential;NASSAUCOUNTY
471817;Residential;NASSAUCOUNTY
983043;Residential;NASSAUCOUNTY
578286;Residential;NASSAUCOUNTY

Step 2: From above step take the column 1 distict value if FILE-1 and find all the values in column 1 of my FILE-2 and write them to output file.
In FILE-2 I want to use the 3rd and 1st column, with the 3rd column being key and 1st column being the values.

e.g. For key
CLAYCOUNTY values are 119736, 448094, 206893, 333743, 172534, 785275, 995932, 223488, 433512
SUWANNEECOUNTY are 640802,403866,828788,751490,972562,367541,481360
NASSAUCOUNTY are 920232,727659, 471817, 983043, 578286

Please provide suggestions to move ahead on this. Thanks.
