Oh, and I would strongly recommend using [[:space:]] instead of [\t ] in the sed expression, something like this: </usr/share/dns/root.ds sed -rne "s/^([.a-ZA-Z0-9]+)([[:space:]]+[0-9]+)*([[:space:]]+IN)*[[:space:]]+DS[[:space:]]+/--trust-anchor=\1,/;s/[[:space:]]+/,/gp" | tr "\n" " " This should work with any DS resource record, not just the root zone.
