Filtering IP address from ifconfig usefule in scripts

print ${$(ifconfig wlan0)[6]}
A method for aquiring the ip address using zsh. If you prefer the use of iproute2 (which, frankly, you should) then the following should provide the same (ip outputs CIDR addresses): print ${$(ip -o -4 a s eth0)[4]} we could also pass a qualifier to take only the IP and not the (CIDR) mask print ${$(ip -o -4 a s eth0)[4]:h} or, similarly, for the MAC address: print ${$(ip l l eth0)[15]}
