thanks iam going to check this module ..
i think you saw the code that posted before your post
#!/usr/bin/perl -w
use strict;
print " please enter the domain name: ";
my $targetdomain = <STDIN>;
chomp $targetdomain;
my $file = "/home/blackice/hello";
open HAN,$file || die "error opening file: $!";
my $comment = 0;
my $block = 0;
while (<HAN>) {
/^zone\s+"$targetdomain"/ and $comment++;
if($comment) {
$block += () = /(\{)/g; # add the number of { matches to $block
s!^!// ! if $comment && $block;
$block -= () = /(\})/g; # substract the number of } matches
$comment = 0 unless $block;
}
print;
}
and my question is how i can make the effects appear in file by commenting the lines without printing it to shell .
