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 Ethereal.

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

While you can do everything you want with various shell tools you'll probably find it much easier to use a higher-level (?) scripting language; perl or whatever alternative you prefer. -- Fraser Campbell <fraser-Txk5XLRqZ6CsTnJN9+BGXg at public.gmane.org> http://www.wehave.net/ Georgetown, Ontario, Canada Debian GNU/Linux -- The Toronto Linux Users Group.
