Would it be possible to wrapper everything in a script that uses a single ping (ping -c 1) to pull the resulting IP address from the output? For example: ping -c 1 google.com PING google.com (74.125.47.103): 56 data bytes 64 bytes from 74.125.47.103: icmp_seq=0 ttl=53 time=111.391 ms --- google.com ping statistics --- 1 packets transmitted, 1 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 111.391/111.391/111.391/0.000 ms seeing how that's the standard output for ping, couldn't you use grep and a regex to grab the IP either from the parenthesis or that first line? Of course there might be an easier way and/or better tool than ping to do this. CCing the list to get a discussion going as I imagine such a script could have other uses. -- Yours In Christ, PIT Emails are not formal business letters, whatever businesses may want.
