Its a shell problem:

csh:
 awk '/[^#]/{ printf("%s IN A %s\n", $2, $1);}' /etc/hosts

bash:
 awk '!/^#/{printf("%s IN A %s\n", $2, $1);}' /etc/hosts

I think this kind of thing was the reason I gave up shell scripts for
anything 1x10-6 serious a long time ago!! Maybe when Linux takes over
the world we will only have to learn bash scripting. ;-)

 Have a good day y'all!

Regards,
Gareth.
