ip-link:tldr:cf808

The command "ip link set ${ethN} address ${ff:ff:ff:ff:ff:ff}" is used to modify the MAC address of a network interface.

Here's a breakdown of the command:

• "ip link set": This is the command to modify network interface settings in Linux.
• "${ethN}": This represents the name of the network interface you want to modify. "ethN" is a placeholder for the actual interface name (e.g., eth0, eth1, etc.). You need to replace ${ethN} with the appropriate interface name.
• "address": This keyword specifies that you want to modify the MAC address.
• "${ff:ff:ff:ff:ff:ff}": This represents the new MAC address you want to set. "ff:ff:ff:ff:ff:ff" is a placeholder for the actual address. You need to replace ${ff:ff:ff:ff:ff:ff} with the desired MAC address. MAC addresses consist of six pairs of hexadecimal digits, separated by colons.

The command, when executed with the correct arguments, will set the new MAC address for the specified network interface.
