Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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.
