Thanks Ahamed. Can you be a little more precise with adding extra parts to the echo/awk command? The current commands are very similar as they are. I am just being introduced to awk and sed so please forgive my lack of knowledge.
Here is some sample data;
Code:
Wed Dec 14 04:41:36 2011 SENT CONTROL [server]: 'PUSH_REQUEST' (status=1)
Wed Dec 14 04:41:36 2011 PUSH: Received control message: 'PUSH_REPLY,route-gateway 197.73.129.164,redirect-gateway def1,dhcp-option DNS 208.67.220.220,dhcp-option DNS 8.8.8.8,dhcp-option DNS 208.67.222.222,route-gateway 197.73.129.164,ping 10,ping-restart 30,ifconfig 197.73.129.170 255.255.255.240'

It is the DNS server IP's that need to be obtained.
It is part of a generic DD-WRT/openwrt script I am creating to allow users to more easily connect to an openvpn server.
The script is stored in the nvram of a DD-WRT router, and when extracted it is executed line by line. There is only one script area available in the http input area, but multiple are files needed, so I need to use echo to create those files, each in the form.
The script is executed everytime the openvpn client successfully connects or reconnects
However then I realised; the command after echo is still not working. Note that the ' marks have been taken away. to get around this "\'" must be used.
Code:
echo awk -F, \''/DNS/{for(i=NF;i>1;i--){if($i~"DNS"){gsub(".* ","nameserver ",$i);print $i}}}'\' l
og
Note that I changed the for loop to search backwards from the end.
Finally, although not as great an issue; Can awk stop after it gets a specific number of results? There are many lines like this containing DNS values, only the 3 are needed. The file may also get rather long so cutting on cpu time and stopping, once the information is obtained, is preferable.

Just add a count which you can check and call exit.
