I want to ping a known MAC address, I tried to use nmap:
sudo nmap -sP 192.168.15.1/24 | grep 20:64:32:3F:B1:A9
But in this case its ping all
Here is another and rather simpler answer.
ping $(arp-scan --localnet | grep 80:1f:02:fa:90:b7 | awk ' { printf $1 } ')
Note that the mac address has to use lower case letters.
arp-scan seems to run much faster than arp.
