I have a file:

pkgName           uuName      tid      status      date1         date2
---------------         ---------      -----      --------      -----------      -----------  
PWCT001584        ve00208      NULL      Closed      20040805      20040805
PWCT001585        ve00208      NULL      Closed      20040805      20040805
PWJR001942        ve00208      NULL      Closed      20040806      20040806
PWJR002109        ve00208      NULL      Closed      20040618      20040618
PWXX001942        ve00208      NULL      Closed      20040806      20040806
PWXX002109        ve00208      NULL      Closed      20040618      20040618
PWCT001584        ve00208      NULL      Closed      20040805      20040805
PWCT001585        ve00208      NULL      Closed      20040805      20040805
PWJR001942        ve00208      NULL      Closed      20040806      20040806
PWJR002109        ve00208      NULL      Closed      20040618      20040618
PWXX001942        ve00208      NULL      Closed      20040806      20040806
PWXX002109        ve00208      NULL      Closed      20040618      20040618
PWXX002110        ve00208      NULL      Pending      20040618      20040618
PWCT001584        au00208      NULL      Closed      20040805      20040805
PWCT001585        au00208      NULL      Closed      20040805      20040805
PWJR001942        au00208      NULL      Closed      20040806      20040806
PWJR002109        au00208      NULL      Closed      20040618      20040618
PWXX001942        au00208      NULL      Closed      20040806      20040806
PWXX002109        au00208      NULL      Closed      20040618      20040618
PWXX002110        au00208      NULL      Pending      20040618      20040618

I need to build a hash containing counts for each uuName, for each group of
packages (where $pkgGroup = substr($pkgName, 0, 4)) for each status, ie.
$pkgCounts{'ve00208'}{'PWCT'}{'Closed'} should return 2
$pkgCounts{au00208}{'PWXX'}{'Pending'} should return 1 ...

This is done in a subroutine. $pkgCounts  is then returned to main for referencing

Here's a script for you. It reads its input from the __DATA__ section. Its output looks like this:


$VAR1 = {
          'au00208' => {
                         'PWCT' => {
                                     'Closed' => 2
                                   },
                         'PWJR' => {
                                     'Closed' => 2
                                   },
                         'PWXX' => {
                                     'Pending' => 1,
                                     'Closed' => 2
                                   }
                       },
          've00208' => {
                         'PWCT' => {
                                     'Closed' => 4
                                   },
                         'PWJR' => {
                                     'Closed' => 4
                                   },
                         'PWXX' => {
                                     'Pending' => 1,
                                     'Closed' => 4
                                   }
                       }
        };




    #!/usr/bin/perl
    use Data::Dumper;

    $r = parse_file();

    print Dumper($r);


    sub parse_file {
        my %pkgCounts = ();

        ## skip first two lines;
        <DATA>, <DATA>;

        while(<DATA>) {

            my ($pkgName, $uuName, $tid, $status) = split ;
            $pkgCounts{$uuName}{substr($pkgName,0,4)}{$status}++;
        }

        \%pkgCounts;
    }
