[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.

You need to create a script that runs cf-dyndns.sh with the arguments 2>&1, which redirects the standard error and pipe to standard out for better error handling.

``bash
#!/bin/bash
echo "[SILENT]" > /root/.hermes/cf-dyndns.sh # Send NO_REPLY message to all three targets in case of errors.
./cf-dyndns.sh 2>&1
if [ $? -eq 0 ]; then
echo "OK: DynDNS Updated"
else
echo "ERROR:"
echo "$(awk -v RS="^STATUS" 'NR>1 {print "\$$1"}}' <<< "$1)"
fi
`

This script checks the output of
cf-dyndns.sh and sends a corresponding message to all three targets based on its error code.

To create the schedule and run this script, you can use CRON. Here's how:

1. Open crontab in edit mode (e.g.,
crontab -e).
2. Add the following line:
*/5 * * * /root/.hermes/cf-dyndns.sh 2>&1
3. Save and exit crontab.

Once this script is running, it will automatically send a message to all three targets when it successfully updates DynDNS for each target within every 5 minutes.

Alternatively, you can modify the existing script with
cf-dyndns to directly run with error handling in case of issues:
`bash
#!/bin/bash

result=$(./cf-dyndns.sh 2>&1)
if [ $? -eq 0 ]; then
echo "OK: DynDNS Updated"
else
echo "ERROR:"
echo "$(awk -v RS="^_STATUS" '$0 ~ /^FAILED$/ || $0 !~ /^SUCCESSFUL$/')" <<< "$result"
fi
`
This script uses the same logic as before but now checks for success/difference in the output of
cf-dyndns` directly inside the variable assignment.
