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)); }'



 Any pointers would be much appreciated.

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

and this too:

 tail -f /var/log/apache2/access.log |awk ' /192.168.1.100/ { system
(mail -s \This works\ m...@email.address)}'

but this below, does not work

 tail -f /var/log/apache2/access.log |awk ' /192.168.1.100/ {  print

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