[Exim] Shell trick help

Message #69816 of 85778 |

OK - I'm running tail on exim logs and extracting IP addresses that
match a specific criteria. So I have a stream of raw IP addresses coming
in that I want to pipe into a program that takes each IP address and
runs a command with the IP address as the parameter.

How do I do that?
