hi there, I am running fBSD 4.7 release. I need to extract my IP address which is dynamically assigned by my ISP and feed it into a serialmail command "maildirsmtp ~alias/pppdir alias-ppp- 1.2.3.4 `hostname` " which is executed from my ppp.linkup. I have to replace hostname with my dynamic IP. I know that my IP always starts with zzz.zzz and if I run "ifconfig | grep zzz.zzz" I get inet zzz.zzz.xxx.xxx --> yyy.yyy.yyy.yyy netmask nnnnnnnnnn Is there a command or something else that I can use in order to get only the IP starting with zzz.zzz up to the first space and how do I feed it into the above command? thanx dj boris
