Hi,

under bash you can try

dns=( $(awk '/nameserver/{print $2}' /etc/resolv.conf ) )

This will give you the second field of all lines matching nameserver read into an array. You can access the data with: echo ${dns[0]}, ${dns[1]} etc.

Kind regards

Chris

ipa-dns-install(1)						 IPA Manual Pages						ipa-dns-install(1)

NAME

       ipa-dns-install - Add DNS as a service to an IPA server

SYNOPSIS

       ipa-dns-install [OPTION]...

DESCRIPTION

       Adds DNS as an IPA-managed service. This requires that the IPA server is already installed and configured.

OPTIONS

       -p DM_PASSWORD, --ds-password=DM_PASSWORD
	      The password to be used by the Directory Server for the Directory Manager user

       -d, --debug
	      Enable debug logging when more verbose output is needed

       --ip-address=IP_ADDRESS
	      The IP address of the IPA server. If not provided then this is determined based on the hostname of the server.

       --forwarder=FORWARDER
	      A  forwarder  is a DNS server where queries for a specific non-resolvable address can be directed. To define multiple forwarders use
	      multiple instances of --forwarder

       --no-forwarders
	      Do not add any DNS forwarders, send non-resolvable addresses to the DNS root servers.

       --reverse-zone=REVERSE_ZONE
	      The reverse DNS zone to use

       --no-reverse
	      Do not create new reverse DNS zone. If used on a replica and a reverse DNS zone already exists for the subnet, it will be used.

       --zonemgr
	      The e-mail address of the DNS zone manager. Defaults to hostmaster@DOMAIN

       -U, --unattended
	      An unattended installation that will never prompt for user input

EXIT STATUS

       0 if the installation was successful

       1 if an error occurred
