set the default device to interact with
usage: fx set-device DEVICE[:SSH_PORT] fx set-device is used to specify the default device to target for fx commands that communicate with a Fuchsia device. A device is set within the scope of a build directory (i.e. out/arm64 may have a different default device than out/x64). If no device name is given, set-device will attempt to discover devices. If one device is found, that device is set as the default for the current build directory. If more than one device is found, the user must select one and provide it to a subsequent invocation of the command. If specified, DEVICE may be a Fuchsia device name that will be resolved using ffx or an IP address. An IPv4 address must be specified directly, while IPv6 need to be surrounded by brackets. SSH_PORT, if specified, will be used for all commands that rely on SSH to connect to the device, instead of the default SSH port (22). Examples: fx set-device strut-wind-ahead-turf fx set-device strut-wind-ahead-turf:222 fx set-device 192.168.1.2 fx set-device 192.168.3.1:8022 fx set-device [fe80::7:8%eth0] fx set-device [fe80::7:8%eth0]:5222 fx set-device To unset, use `fx unset-device`.
