[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.

This is a command to run a cron job that updates the DynDNS records dynamically. The goal of this task is to ensure that all three targets - Telegram, Discord, and the sender's DM (Direct Message) - receive updates on changes in service availability.

Here's an explanation of each step:

### Step 1: Run the Cron Job

Firstly, you will run this command:
``bash
bash /root/.hermes/cf-dyndns.sh
`
Replace
/root/.hermes/ with the actual location of your Hermes account settings (e.g., in GitHub).

This command loads a script named
cf-dyndns.sh, which is located at that path. When you save this file and add it to your cron table, it's executed automatically during midnight.

### Step 2: Handle DynDNS Updates

The next step involves handling DynDNS updates successfully:

`bash
if [ $? -eq 0 ]; then
for i in "telegram:-1003980922525": "discord:1511697499654459422"; do
if ! web_search "dyndns update $i"; then
message="โš ๏ธ DynDNS Error: []"
break
fi
done
fi
`

- The
if [ $? -eq 0 ];, it checks the job success status with $?.
- Inside a nested loop for every target, we check if any search results related to an update were found using
web_search.
- If no matching results are generated, we return without any output and break out of the current iteration with
break.

### Step 3: Send Messages

If updates were successfully made (i.e., they didn't show a status
NO_CHANGE), then:

`bash
for i in "telegram:-1003980922525": "discord:1511697499654459422"; do
message="๐Ÿ”„ DynDNS Updated: [search output]"
reply_message "$message"
done
`

- The response sends messages for the targets if changes were made.
`bash
reply_message() {
echo "$(web_extract "^$1" "DynDNS update $i')"
}
