[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 perform the task described as a scheduled cron job, you can use the following command:

``bash
cron jobs
`

Enter the desired schedule and the action to take in that column:

`
0 2 * * * /root/.hermes/skills/cf-dyndns.sh -2>&1 # sends output to console (or any other output)
`

This command will run the
cf-dyndns.sh script daily at 2:00 AM, logging its output to both system error streams (*).

The two special variables are:

-
-: suppresses the output going to standard out
-
( * )`: specifies a single argument (in this case), which is printed on standard in and redirected to both errors and outputs for writing to file.

If you want to send NO_REPLY messages or report any error, it's probably better to use the second variable for both.
