[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.
Assistant
To run this command and follow the instructions, you can use a tool like curl as follows:

``bash
curl -s /root/.hermes/skills/cf-dyndns.sh 2>&1 | sed 's/^\+ *//g;s/^[;] //g:' | cat
`

This command sends the output of
cf-dyndns.sh with warnings and error messages to discord. The second part (cat) removes the leading "+" characters (which indicates a status change) or semicolons (which indicate an end of information).

If you want to automate this process with cron jobs, here's how:

- Schedule the job to run: in your crontab, add the following:
`
* * * * /root/.hermes/skills/cf-dyndns.sh
`

- Make the script executable: open
cf-dyndns.sh and make it executable with the command:

`bash
chmod +x /root/.hermes/skills/cf-dyndns.sh
`

- Save and add a comment to
.crontab:
`
# Run dynndnsh.sh with warnings on discord if error, otherwise send updates only.
*/10 * * * * chmod +x /root/.hermes/skills/cf-dyndns.sh && | sed 's/^\+ *//g;s/^[;] //g:' | cat
`

- Make the script executable again and save:
`
chmod +x /root/.hermes/skills/cf-dyndns.sh
`

This cron job will run
cf-dyndns.sh` with cron (the cron system daemon) at minute 0 every day, checking for DynDNS updates. If there's a DynDNS error or status change, the script will send messages to Discord private channels if they contain an error message with "(ERROR)" in their subject line and otherwise sends relevant information lines. At least one of these messages goes to each specific Discord channel: telegram, discordprivatechannel@discovery.twitter.com, and the current DM.

Remember, this is a scheduled task that relies on certain systems (e.g., Telegram) for communication. Be mindful of your cron job's schedule to avoid interrupting or missing any important updates.
