wol: Send a WoL packet to a device in another subnet based on its hostname.

$ wol --host=${hostname} ${mac_address}

try on your machine

The given command is used to send a Wake-on-LAN (WoL) signal to wake up a remote device on a local network. Here's what each part of the command does:

wol: This is the command to trigger a Wake-on-LAN signal. It is typically part of a network utility or package installed on a computer or server.
--host=${hostname}: This is an argument passed to the wol command. ${hostname} is likely a placeholder for a variable that should be replaced with the specific hostname or IP address of the target device that you want to wake up. For example, this could be --host=192.168.0.100 or --host=mydevice.local.
${mac_address}: This is another argument passed to the wol command. ${mac_address} is likely another placeholder for a variable that should be replaced with the MAC address of the target device. The MAC address is a unique identifier assigned to network interfaces, and it is used to identify the specific device you want to wake up.

When executed, the wol command with the given arguments sends a specially crafted network packet, containing the MAC address of the target device, to the local network. This packet is broadcasted to all devices on the network, and the device with the matching MAC address should listen for it and initiate a wake-up procedure, often by powering on from a sleep or hibernation state.
