What Others Think

The awk bit also catches the summary line at the end as it stands. If you just want the hosts, try this: nmap -sP your network/submask | awk "/^Host/"'{ print $2 }'

Command exists in here several times. Do try a grep of the archive before posting. In your defense, I got this same message for my first post. Ironically, for this same command :-/ Also, on networks that allow named hosts (like mine), the line reads #Host aveil (192.168.0.144) appears to be up. and so you would print out the machine name, not the network. Machines that don't have names, will then cause both ips and names to print out, which would look odd. lan|grep Host |grep -oE '[0-9]+\.[0-9\.]+' will filter out only IP addresses from such networks.

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
