            // But it varies. We need to be careful.
            // The original code used:
            // const realmac = arraystdout[4];
            // const ip_address = arraystdout[0];
            // const actualstatus = arraystdout[5];

            // Let's try to map it based on the split.
            // Example: 192.168.1.154 dev br0 lladdr 04:d9:f5:x:x:x STALE
            // split(" "): ["192.168.1.154", "dev", "br0", "lladdr", "04:d9:f5:...", "STALE"]
            // Indices: 0=ip, 4=mac, 5=status.

            // If there are extra spaces and we use split(" "), we get empty strings.
            // If we use split(/\s+/), we get clean tokens.

            // We will return the raw array so the main logic can pick what it needs,
            // or we can normalize it here.
            // To keep changes minimal in main.js, let's just return the structure expected or let main.js handle the array.
            // But main.js expects `arraystdout` to be the split array.
            // So let's just return the split array and the mac.

            devices.push({
                mac: mac,
                tokens: arraystdout,
