I would suggest to keep the system() approach:
tail -f /var/log/apache2/access.log | awk '/192.168.1.100/ {
system(sprintf("echo %s | mail m...@email.address", $0)); }'

It should work, but I'm sure someonle else will soon show you
some more elegant way. :-)

You might want to look at ``swatch'' which is designed to do
this, and monitors multiple log files simultaneously.

Capitalism works primarily because most of the ways that a company can be
scum end up being extremely bad for business when there's working
