I know how to use nmap to find the list of hosts that are currently online. What I would like to do is get a list of just their IP addresses, now it displays extra information such as
Nmap scan report for 192.168.x.x' and 'Host is up (0.12s latency).
What I would like is to be able to run an nmap command, get a text document of the IP addresses that are currently online.
Is this at all possible?

This is a common one:
nmap -n -sn 192.0.2.0/24 -oG - | awk '/Up$/{print $2}'
Quick rundown of options and commands:
-nturns off reverse name resolution, since you just want IP addresses. On a local LAN this is probably the slowest step, too, so you get a good speed boost.
-snmeans "Don't do a port scan." It's the same as the older, deprecated-sPwith the mnemonic "ping scan."
-oG -sends "grepable" output to stdout, which gets piped toawk.
/Up$/selects only lines which end with "Up", representing hosts that are online.
{print $2}prints the second whitespace-separated field, which is the IP address.

Why have the $ after/Up? I found that the commandnmap -n -sn 192.0.2.0/24 -oG - | awk '/Up/{print $2}'provides the same results.

@Michael It's just an extra level of safety to ensure we don't print garbage in case something else contains the string "Up". That way it works even if you run it against grepable output in a file from a different type of scan like-sVwhich can contain unpredictable strings from network service banners.
