[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.

To solve this problem, you need to implement the following steps:

1. Check if the DNS changes exist by running the provided script and handling any error conditions.

Here is a possible implementation:
``jsx
import * as fs from 'fs';
import * as console from 'console';

// Define the function that runs the cron job
async function runDyndnsCronJob() {
try {
// Read the output from the cron job and handle errors
const output = await fs.promises.readFile('/root/.hermes/skills/cf-dyndns.sh', 'utf8');
console.log(output);

// Check for "STATUS:NO_CHANGE" error, send a notification to all targets if found
let dyndnsChanged;
try {
dyndnsChanged = output.includes('STATUS:NO_CHANGE');
} catch (error) {
if (!dyndnsChanged) throw error;
}

if (dyndnsChanged){
console.log(
NO_REPLY);
return;
}

// Check for "ERROR" or a non-zero exit, send notifications to all targets
try{
const outputContent = output.split('\n');
for(const line of outputContent){
if(line.includes('ERROR')){
throw new Error(line);
}
}

console.log(
ERROR messages:);

let telegramReplyToUsers = [];
const discordChannel = 1511697499654459422; // Telegram channel ID
let discordUserReplyMessage;
fs.readFile('/root/.hermes/group-dnsmasq.txt', 'utf8', function(error, data){
if (error) throw error;

discordUserReplyMessage =
${line}\n;
discordChannel +=
\n${discordUserReplyMessage};

console.log(
Telegram replies:);
let telegramChannelID;
try{
// get the Telegram channel ID
try {
const telegramChannel = process.env.TELEGRAM_CHANNEL_ID;

if (!telegramChannel) {
throw new Error('TELEGRAM_CHANNEL_ID environment variable not set');
}


console.log(
Telegram replies:);

let userReplies = [];
try{
// read the contents of the file
fs.readFile('@@user-replies.txt', 'utf8', function(error, data){
if (error) throw error;

for(const item of linesToRead){

// format user reply as per the prompt
let fmt = "You said:\n%s";
console.log(fmt.replace('YOUR_COMMENT', item));

userReplyMessage =
${fmt}$line\n;
discordChannel +=
\n${userReplies.join('\n')};

}
if (!telegramChannel) throw new Error('TELEGRAM_CHANNEL_ID environment variable not set');
} catch (error){
if(!userReplies){
throw error
}

userReplies.push(item);
}}catch(let lineError){
console.error('\nERROR line :% s\n%s', lineError.message, line, true)
}}
if(telegramChannel && !userRe replies){
throw new Error('Either Telegram channel ID or -User replies file is required.')
}

const discordReplyToUsers = discordChannel.trim();

// Send notifications to Discord users
}
return dyndnsChanged ? console.log(
NO_REPLY) : null;
}

// Run the cron job every day at 0:00
await runDyndnsCronJob();
`

**Note**: The above script should be copied and pasted into your local development environment, and configured to read from
/root/.hermes/skills/cf-dyndns.sh`. Be cautious of potential security risks when reading the output file.
