Hi, thanks for your reply. I succeeded with below.Now, it's OK. 

$clean_total =~ s/^\s+|\s+$//g;
$spam_total =~ s/^\s+|\s+$//g;
$virus_total =~ s/^\s+|\s+$//g;
$banned_total =~ s/^\s+|\s+$//g;
$badheader_total =~ s/^\s+|\s+$//g;
$reject_total =~ s/^\s+|\s+$//g;

Anyway, I checked with chomp($clean_total) as well. It also worked. Anyway, what is better? Here's my code

my $str = qx(date);
print $str;

This works as expected. I would like to test your other perl code too.Since it is very very perl way. One more question is remaing. How can change font size of values on the top of the bar.
