I would like to extract specific information from lines in log files and 
perform math functions on them. Grep is ok for getting the lines I want and 
putting them where I want them. But I've reached a limit in what I can do 
because I lack the education.

Two things I need to learn:

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

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

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?
