In Pi we have the path of lease file is /var/lib/misc/dnsmasq.leases

In Ubuntu it is /var/lib/NetworkManager/*.lease in some cases (specially with dhcpd) it is
/var/lib/dhcp/dhcpd.leases

For pi we can display the IP address of named device by cat /var/lib/misc/dnsmasq.leases | grep "ClienDevName"|cut -d " " -f 3| awk '{print $1}'

in this command -d is for "delimiter" which is space by " " and -f 3 is to print the 3rd value after cutting with delimiter space i.e " ".
