Search and Destroy Script Direction Help
Being a beginner in scripting I am not sure the direction to take to accomplish the below task and would love suggestions.

GOAL
input file: domains.list
Read input file, search in named.conf and find domain and delete entry for the purpose of cleanup activity.

named.conf entry example
Code:
zone "hosangit.biz" {
                type slave;
                file "primary.dir/db.hosangit.biz";
                masters { 192.8.15.7; };
};

So the file somehow needs to read line by line the domains then look in the named.conf for exactly "hosangit.biz" (not na.hosangit.biz) and then remove everything from the word zone to the last }; prompt

Take into account the entry may be commented out like the following
Code:
//zone "hosangit.com" {
//        type slave;
//        file "primary.dir/db.hosangit.com"
//    masters { 192.8.15.8; };
//};

Would love to have a list of what was removed as well so I can validate everything is okay.

Suggestions on which route to take? Is this doable in korn scripting or awk scripting. I think someone said sed would be helpful with the searching portion. Again, I'm new and want to learn. Instead of altering 2000+ domains on 5 different servers manually (which I have been doing) it seems there should be a way to do this via a script.

Any help is appreciated.

Do you want the commented out zones to be removed as well?

Yes, that would be part of it as well. A complete clean up activity of the named.conf of anything that is in the domains.txt input file

Try this as a starter. domains.txt is not yet read, but ...
Code:
awk     '/{/            {CNT++}
         /}/            {CNT--}
         $0 ~ SRCH      {FN=SRCH".txt"}
         CNT && FN      {print $0 > FN; next}
         !CNT           {FN=""}
         1
        ' SRCH="\"hosangit.biz\"" file

Thanks, it worked pretty good.

It didn't remove the last };

Before snapshot
Code:
zone "djzah.com" {
      type master;
      file "trade.dir/db.djzah.com";
};

zone "hosangit.biz" {
        type slave;
        file "primary.dir/db.hosangit.biz";
        masters {20.10.3.5; };
};

AFTER script
Code:
zone "djzah.com" {
      type master;
      file "trade.dir/db.djzah.com";
};

};


So that trailing };

I also tested the commented out zone's
Before
Code:
zone "djzah.com" {
      type master;
      file "trade.dir/db.djzah.com";
};

//zone "hosangit.biz" {
//        type slave;
//        file "primary.dir/db.hosangit.biz";
//        masters {20.10.3.5; };
//};

After
Code:
zone "djzah.com" {
      type master;
      file "trade.dir/db.djzah.com";
};

//};

So you can see the extra or left behind is the //};

OK, try this one:
Code:
awk     'FNR==NR        {T[$1]++; next}
         /{|}/          {CNT += gsub (/{/,"&") - gsub (/}/,"&")}
         /zone/         {for (i in T) if ($0 ~ i) {FN=i".txt"}; gsub (/"/,"",FN)}
         FN             {print > FN; if (!CNT) {FN=""}; next}
         1
        ' domain.txt file

That code works great RudiC exporting the actual entire zone into its own text file. (Creating Backups of the domains). I'll admit the code is way advanced. I'm going to try and break down each of your steps so I can learn how you did it and see if I can apply it to the remove portion. Thank You for giving me that push.
