networkctl:tldr:8caaa
The command "networkctl down ${interface1 interface2 ---}" is not a valid command. It seems like there is a mistake in the syntax. However, assuming that "interface1" and "interface2" are placeholders for the actual names of network interfaces, the command could be an attempt to bring down multiple network interfaces simultaneously using the networkctl utility. The "networkctl" command is used to control and inspect the systemd-networkd network manager, which is responsible for managing network interfaces and connections on a Linux system. The "down" option is used to disable the specified network interfaces, effectively bringing them offline. By providing multiple interface names as arguments separated by spaces, it suggests that the intention is to bring down multiple interfaces at once. Here's an example of how the command could be constructed correctly, assuming "eth0" and "wlan0" are the interface names to be brought down simultaneously: networkctl down eth0 wlan0
