add new entries one per line. then if one line fails due to an unresolvable name, your other lines won't be affected:
pfctl -t goodguys -T add host1.no-ip.org pfctl -t goodguys -T add host2.no-ip.org pfctl -t goodguys -T add no-such-name.xxx.yyy pfctl -t goodguys -T www.host3.nu in the above example, a failure of any one line (such as line 3) won't prevent your other lines from being attempted. -ken On Mon, Mar 9, 2015 at 12:16 PM, Leslie Jensen <jensen.les...@gmail.com> wrote: > Hello list. > > I have a problem with a simple script I've written to keep two tables up > to date.
