What Others Think

Kudos for awk-ing this. :-) Just wondering if there is a shorter equivalent? < file.name xargs resolveip

resolveip seems to be a MySQL-installed command. For those that don't have MySQL on their systems, try this: dig +short -f filename dig +short +noshort -f filename dig +noall +question +answer -f filename and so on for various types and verbosities of responses You can also pipe stuff in and use "-" as the filename: dig [options] -f - < filename

Apologies for not mentioning it was a mysql utility; it's rare i bump up against a system that doesn't have at least a minimal mysql installed.
