Show me just the ip address

showip() { nmcli connection show $1|grep ipv4.addresses|awk '{print $2}' ; }
Sometimes it's useful to output just the ip address. Or some other information, changing the "ipv4.addresses" in command. The power of awk! Show all possible "greps" with nmcli connection show [yourInterfaceNameHere]
Sample Output
$ showip eth0
10.0.2.100/24
$ showip eth1
10.0.2.7/24
...

What Others Think

try awk '/ipv4.addresses/ {print $2}' to do the pattern match and field selection in one command.

Ah, @snegtul beat me. However, the command doesn't work on my version of nmcli (Fedora 21) nmcli --version nmcli tool, version 0.9.10.2-2.fc21 nmcli connection show eth0 ipv4.addresses: { ip = 192.168.0.100/24, gw = 192.168.0.1 } so the simplest solution for me is sed: ... | sed '/ipv4.addresses/s/.* \(.*\),.*/\1/' Search for something delimited by space (before) and comma (after).

I've just lernt that nmap --iflist is useful to show all ifaces, ip and routes. ..of course this doesn't work if we're looking for the ip to use it in a bash script.
