Linux How To Find MAC Address
Any of these commands will show you a list of interfaces on the system. The output will include the MAC address for each interface.
ifconfig -a ip addr ip a ip link
Show the info for a specific interface using either of these two commands:
ip addr show eno2 ifconfig eno2 ethtool eno2
You can use the “-p” parameter to grab the MAC address line like this:
ethtool -P eno2
Note that the ip command is newer than the ifconfig command and is more likely to be installed on newer systems.
