Tanktalus provided excellent directions on how to achieve your goal. With just a little more work, the script I've shown you can accomplish these items. For example:

while ( my $row = $csv->getline($csvfh) ) {
    next if $row->[6] eq 'Outbound';
    push @csvLines, $row;
}
[download]

will skip all lines containing 'Outbound' in your shown data set. You can manipulate the row data right after next, to get what you need before pushing the line onto @csvLines.

How do you want to separate Call Start Time and which three columns do you want to delete?
