Actually, sorry to disappoint you, but it won't. That " grep ' " in
there is probably meant to be lo0 for this to work on Linux. And at
the end of the command, the quotes around sed's expression are probably
the other way around, as in
"sed -e 's/.*://'`", instead of
"sed -e 's/.*://`'".
^^ see here
One way to get the IP address of an interface in BSD is by using netstat
and a few pipes to do the filtering of netstat's output.
% netstat -in | grep lo0 | grep -iv link | awk '{print $4}'

No need to, ipfw works fine with dynamic IP addresses too :-)
