nmap is useful, but an overkill.

You can use prips instead. Saves you the hassle of grepping out the extra output from nmap and using awk.

Calling prips 192.168.0.0/23 will print what you need.

I use the following to skip the network address and broadcast: prips "$subnet" | sed -e '1d; $d'

Prips also has other useful options, e.g. being able to sample every n-th IP.

It's available via apt,brew,rpm and as tar.gz.
