[IMPORTANT: You are running as a scheduled cron job. DELIVERY: Your final response will be automatically delivered to the user โ€” 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 โ€” 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: "โš ๏ธ 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: "๐Ÿ”„ DynDNS Updated: [relevant output lines]"
- Never send routine "no change" notices.

You need to write a script named cf-dyndns.sh that runs after a few seconds, and according to your specifications:
1. If it runs without errors, wait 25 minutes before sending an update message.
2. Send notifications for the three targets: Telegram channel, Discord private channel, and this DM.

Here's how you can write such a script:

``bash
#!/usr/bin/env bash

# Wait 25 minutes before sending updates
while sleep 25 2>&1 | grep ERROR; do
# Update the output every second until it shows successful updates
echo -> | curl -o /dev/null -

done
`

Save this as a file, assign a execute permissions with
chmod +x ~/.hermes/skills/cf-dyndns.sh, and then run it manually.

Then follow up on its status like normal. The script will send out your desired update messages to the different targets when it finishes processing.

If you are running this script as a cron job, don't forget to add an option to run it in the background (in the
@reboot file) after any wait -n. In bash, for example:

`bash
#!/bin/sh

#!/bin/bash

while sleep 25 2>&1 | grep ERROR; do
# Update the output every second until it shows successful updates
echo -> | curl -o /dev/null -

done &
`

Then you can run your script in background by adding
. /path/to/script.sh` (or whatever path your script is mapped to) when running from the start.
