[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.

Assistant

To monitor the status of Dynamic DNS (DDNS) using a cron job, you can use the cf-dyndns.sh script as shown in the example response.

This command checks for DDNS updates and sends notifications to specific Telegram channels when something changes.

Here's how you can modify it to run in the background:

``bash
* * * * *
/root/.hermes/skills/cf-dyndns.sh 2>&1 | grep -vE 'STATUS NO_CHANGE'
`

This command will run the cf-dyndns.sh script at minute intervals. If any lines that start with "STATUS:NO_CHANGE" are found, it will send a notification to the specified channels.

Note: You need to make sure you have a .hermes configuration directory in your system for this setup to work properly.

Additionally, the -o 2>&1 option tells grep to capture both the stdout and stderr of the command it's searching. The | symbol is used to pipe that output into grep.

If you want to send an actual message instead of just a warning or no reply for successful updates:

`bash
* * * * *
/root/.hermes/skills/cf-dyndns.sh 2>&1 | grep -vE 'STATUS NO_CHANGE'
echo "DynDNS Updated: $\?" > /tmp/dynos_output.log
`

This will create a log file named dynos_output.log` to store the actual output of the DDNS update. The last line of the regular expression is where you send a notification, which logs information about each successful update.

Remember that sending status updates in real-time can be resource-intensive if there are many servers being updated, and it's also subject to timing issues without sufficient logging or error handling mechanisms around it.

To use this setup safely, make sure that the system has enough resources (CPU power, memory) to handle the cron job and its scheduled notifications.
