When using the -d option I find it frustrating that arbitrary whitespace ruins the field count.
witness this script:
dig -x $addr +noall +answer | grep -v '^;' | grep -v '$^' | expand | cut -d' ' -f5 -z
With the new option in this patch, you can rely on the behavior to
produce a hostname if there is one. Otherwise you cant.
How about filtering the output through tr -s ' ' just before cut? Then your script won't have to rely on less-portable features.
Thanks for your feedback and for the tip.
