[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 dyn DNS status and notify the targets directly when there is an error or a successful update, you can use the following command:

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

This will run the
cf-dyndns.sh script whenever it receives output. The script checks for certain conditions and sends messages to specific targets if it finds an error or a successful update.

Here's how it works:

-
/root/.hermes/skills/cf-dyndns.sh is where you should put your script that runs the dyn DNS service.
-
2>&1 redirects any output of the script (which may be different from the return values) onto the standard error stream (stderr).
-
!/shell ... makes cf-dyndns.sh a single shell command, which is equivalent to /root/.hermes/skills/cf-dyndns.sh.

To receive notifications when dyn DNS status has changed, you can modify the script like so:

`bash
#!/bin/bash

# Define the channels for sending notifications
TARGETS=(0telegram 1discord telegram:1812605657)

# ... rest of your script ...
`

When your
cf-dyndns.sh script finds an error or a successful update, it will add this to the TARGETS array.

Then you don't need to run any commands outside of your script. The
tf-notify utility can handle sending notifications for you:

`bash
tfnotify -c /root/.hermes/skills/cf-dyndns.sh -t telegram:1003889822515 -t discord:151169749965446,1234567890 2>&1
`

This will send NO_REPLY if the output only shows "STATUS:NO_CHANGE", but it will send an error message if any other text is in the
stdout` and not NULL. It also will send a message every time you run it.
