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
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
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.
What is a good way to find an entry in a .conf file and then remove all lines associated with that entry?

resolvconf.conf
RESOLVCONF.CONF(5) System Manager's Manual RESOLVCONF.CONF(5)NAME
resolvconf.conf -- resolvconf configuration file
DESCRIPTION
resolvconf.conf is the configuration file for resolvconf(8). The resolvconf.conf file is a shell script that is sourced by resolvconf(8),
meaning that resolvconf.conf must contain valid shell commands. Listed below are the standard resolvconf.conf variables that may be set.
After updating this file, you may wish to run resolvconf -u to apply the new configuration.
RESOLVCONF OPTIONS
interface_order
These interfaces will always be processed first. If unset, defaults to the following:-
lo lo[0-9]*
dynamic_order
These interfaces will be processed next, unless they have a metric. If unset, defaults to the following:-
tap[0-9]* tun[0-9]* vpn vpn[0-9]* ppp[0-9]* ippp[0-9]*
search_domains
Prepend search domains to the dynamically generated list.
search_domains_append
Append search domains to the dynamically generated list.
domain_blacklist
A list of domains to be removed from consideration. To remove a domain, you can use foo.* To remove a sub domain, you can use *.bar
name_servers
Prepend name servers to the dynamically generated list. You should set this to 127.0.0.1 if you use a local name server other than
libc.
name_servers_append
Append name servers to the dynamically generated list.
name_server_blacklist
A list of name servers to be removed from consideration. The default is 0.0.0.0 as some faulty routers send it via DHCP. To remove
a block, you can use 192.168.*
private_interfaces
These interfaces name servers will only be queried for the domains listed in their resolv.conf. Useful for VPN domains. This is
equivalent to the resolvconf -p option.
state_dir
Override the default state directory of /run/resolvconf. This should not be changed once resolvconf is in use unless the old direc-
tory is copied to the new one.
LIBC OPTIONS
The following variables affect resolv.conf(5) directly:-
resolv_conf
Defaults to /etc/resolv.conf if not set.
resolv_conf_options
A list of libc resolver options, as specified in resolv.conf(5).
resolv_conf_passthrough
When set to YES the latest resolv.conf is written to resolv_conf without any alteration.
resolv_conf_sortlist
A libc resolver sortlist, as specified in resolv.conf(5).
resolv_conf_local_only
If a local nameserver is configured then the default is just to specify that and ignore all other entries as they will be configured
for the local nameserver. Set this to YES to list them instead, if you need working DNS and the local nameserver stops functioning
at the expense of duplicated server queries.
SUBSCRIBER OPTIONS
openresolv ships with subscribers for the name servers dnsmasq(8), named(8), pdnsd(8) and unbound(8). Each subscriber can create configura-
tion files which should be included in in the subscribers main configuration file.
dnsmasq_conf
This file tells dnsmasq which nameservers to use for specific domains.
dnsmasq_resolv
This file tells dnsmasq which nameservers to use for global lookups.
Example resolvconf.conf for dnsmasq:
nameservers=127.0.0.1
dnsmasq_conf=/etc/dnsmasq-conf.conf
dnsmasq_resolv=/etc/dnsmasq-resolv.conf
Example dnsmasq.conf:
listen-address=127.0.0.1
conf-file=/etc/dnsmasq-conf.conf
resolv-file=/etc/dnsmasq-resolv.conf
named_options
Include this file in the named options block. This file tells named which nameservers to use for global lookups.
named_zones
Include this file in the named global scope, after the options block. This file tells named which nameservers to use for specific
domains.
Example resolvconf.conf for named:
nameservers=127.0.0.1
named_options=/etc/named-options.conf
named_zones=/etc/named-zones.conf
Example named.conf:
options {
listen-on { 127.0.0.1; };
include /etc/named-options.conf;
};
include /etc/named-zones.conf;
pdnsd_conf
This is the main pdnsd configuration file which we modify to add our forward domains to. If this variable is not set then we rely on
the pdnsd configuration file setup to read pdnsd_resolv as documented below.
pdnsd_resolv
This file tells pdnsd about global nameservers. If this variable is not set then it's written to pdnsd_conf.
Example resolvconf.conf for pdnsd:
nameservers=127.0.0.1
pdnsd_conf=/etc/pdnsd.conf
# pdnsd_resolv=/etc/pdnsd-resolv.conf
Example pdnsd.conf:
global {
server_ip = 127.0.0.1;
status_ctl = on;
}
server {
# A server definition is required, even if emtpy.
label="empty";
proxy_only=on;
# file="/etc/pdnsd-resolv.conf";
}
unbound_conf
This file tells unbound about specific and global nameservers.
Example resolvconf.conf for unbound:
nameservers=127.0.0.1
unbound_conf=/etc/unbound-resolvconf.conf
Example unbound.conf:
include: /etc/unbound-resolvconf.conf
