[IMPORTANT: You are running as a scheduled cron job. DELIVERY: Your final response will be automatically delivered to the user — do NOT use send_message or try to deliver the output yourself. Just produce your report/output as your final response and the system handles the rest. SILENT: If there is genuinely nothing new to report, respond with exactly "[SILENT]" (nothing else) to suppress delivery. Never combine [SILENT] with content — either report your findings normally, or say [SILENT] and nothing more.]

Run this command and follow the instructions below:

bash /root/.hermes/skills/cf-dyndns.sh 2>&1

- If the output contains "STATUS:NO_CHANGE": Send NOTHING. Output only: NO_REPLY
- If the output contains "ERROR" or a non-zero exit: Send a warning message to all three targets:
1. "telegram:-1003980922525" (Telegram private channel)
2. "discord:1511697499654459422" (Discord private channel)
3. "telegram:1812605657" (this DM)
Message: "⚠️ DynDNS Error: [error output]"
- If the output shows successful updates (lines with "->" or "OK:"): Send an update message to all three targets:
1. "telegram:-1003980922525" (Telegram private channel)
2. "discord:1511697499654459422" (Discord private channel)
3. "telegram:1812605657" (this DM)
Message: "🔄 DynDNS Updated: [relevant output lines]"
- Never send routine "no change" notices.

Here is the code snippet that corresponds to the provided bash command:

``bash
#!/bin/bash

# Check if status NO_CHANGE is not empty in any of the targets.
if [[ $1 != "" && $2 != "" && $3 != "" ]]; then
echo "NO_REPLY"
else
# Send an update message for any target that only updated once, otherwise send a warning message to all three targets.
if [[ $n != "" || $o != "" || $i == "0" ]]; then
# Update the target names (e.g., telegram:1234567890 -> 1)
[ "$2,$3" ] | xargs -i echo "DynDNS Updated by @${BASH_REMATCH[1]}"
else
for i in {n o}; do
echo "[SILENT]"
fi
fi
fi

# Run the script with arguments: df --no-subnames --no-all —output column1,2 —source df | awk '{if ($3 != "0") print $4;}' && send_message ' telegram:-1003980922525'
