Sounds like the most straightforward way to me, and I prefer to KISS.
I made two such scripts that negate each other - each turns on
different DNS settings by commenting and de-commenting different
sections in resolv.conf.
Both are basically same:
- vi -w on /etc/resolv/conf
- %s/^nameserver/#&/
- /<header of desired DNS settings section
- j
- v}
- s/^#//

only the section header is different. However while one of them gets
the job done the other fails miserably. Since the script is in binary
and running to fast to follow I can't really troubleshoot why.

I think its time to call perl to the rescue :)
Thanks for the answers.
