1 - How I can search for subnet matches in /var/log/messages, like I can in Ethereal.

Are you aware of the ability to do regex expressions in grep? This should do exactly what you want.

2 - How I can extract $omefield (columns?) and print $ame to $omefile after doin $ummath on $omefield.

If I was sticking to shell I'd use "cut" here.

I've been looking at man pages and am thinking awk sort uniq ... am I looking in the right direction? Are there any cautionary comments with shell tools as powerful as awk? What are '.po' files?

Shell tools tend to have a narrower focus than awk but each is very powerful in what it does.
