hi hipowls, i pasted your codes into the following 
my $in_file = "$logfile";
open my $in_fh, '<', $in_file or die "Could not open file $in_file: $!
++";

my $out_file = 'output.txt';
open my $out_fh, '>', $out_file or die "Could not open file $out_file:
++ $!";

while ( my $line = <$in_fh> ) {
    print {$out_fh} $line if $line =~ /production/;
}
my %stats;
while ( my $line = <$file> ) {
    next unless $line =~ /TWO/;
    my ($time) = $line =~ /^(\d\d\d\d-\w\w\w-\d\d \d\d)/)/;
    ++$stats{$time};
}
close $in_fh  or die "Could not close file $in_file: $!";
close $out_fh or die "Could not close file $out_file: $!";
