ip-link:tldr:741b1

This command is used to set an alias for a network interface on a Linux system.

Let me break down the command for you:

• ip link set: This is the command to modify the attributes of a network interface.
• ${ethN}: This is a placeholder for the name of the interface you want to modify. The 'N' represents a number or identifier of the interface, such as eth0, eth1, etc. You need to replace ${ethN} with the actual name of the interface you want to set an alias for.
• alias: This is the keyword used to specify that you want to set an alias for the interface.
• "${LAN Interface}": This is another placeholder representing the alias you want to set. You need to replace ${LAN Interface} with the desired name for the alias. The name should be enclosed in double quotes.

For example, if you want to set an alias for the interface eth0 with the name "LAN Connection", the command would look like:

ip link set eth0 alias "LAN Connection"

After executing this command, the specified network interface will have an alias associated with it.
