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;
It is the DNS server IP's that need to be obtained.
The following creates the resolv.conf
Again your help is much appreciated.
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
The above didnt work, this helped.
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.
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.
