ip-link: Bring a network interface up or down.
$ ip link set ${ethN} ${select}
try on your machine
The command "ip link set ${ethN} ${select}" is used to modify the configuration of a network interface in Linux.
Here's a breakdown of the command:
- "ip link" is a command-line tool used to manipulate network devices or interfaces.
- "set" is the subcommand that specifies that we want to change the configuration of a network interface.
- "${ethN}" is a placeholder for a specific network interface (e.g., eth0, eth1) that you want to modify. The actual interface name should be provided in place of "${ethN}".
- "${select}" is a placeholder for the configuration you want to apply to the network interface. This can be one or more options such as enabling or disabling the interface, changing the speed, setting the MAC address, etc. The specific option(s) should be provided in place of "${select}".
To use this command, you need to replace "${ethN}" with the actual network interface name and "${select}" with the desired configuration option(s) for that interface.

never run a command you are not sure if it is safe.
