[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 handle the output from the cf-dyndns.sh command, you can create a script that captures and processes the output. Here's an example of how you might do this:
``bash
#!/bin/bash

echo "Delivering..."

while read -r line; do
case $line in
":")
echo "status: NO_CHANGE"
;;
NO_changes)
echo "receiving..."
break
;;
*)
echo "Updating DynDNS: ${line]"
;;
esac
done < /dev/stdin | tr -d '' < <(cat /root/.hermes/skills/cf-dyndns.sh)

echo "Sending outputs:"
echo "Telegram private channel: $(cut -d';' -f2 < <(tail -n1 /root/.hermes/skills/cf-dyndns.sh | tr ',' '\n'))"
echo "Discord private channel: $(cut -d';' -f3 < <(tail -n1 /root/.hermes/skills/cf-dyndns.sh | tr ',' '\n'))"
echo "Text message to the sender in this DM: $(cut -d';' -f4 < <(tail -n1 /root/.hermes/skills/cf-dyndns.sh | tr ',' '\n'))
`
This script captures each line of output from the
cf-dyndns.sh command and processes it accordingly. If it encounters a line starting with :, it logs the message as "no change". If it encounters an error message, it sends a warning to all three recipients. Otherwise, if it finds a line indicating that the DynDNS updates were successful (-> or OK:), it sends an update notice.

Note that this script assumes that the output from
cf-dyndns.sh is piped into /dev/stdin`. If you want to capture the output of your cron job differently, you'll need to modify the shebang line and the way you pass input to the script.
