To add a command-line interface (CLI) and command-line arguments (args) to PhantomJS when using Selenium WebDriver in Node.js, you can modify your existing code as follows. I’ll provide you with a step-by-step guide and also explain the changes made:

const webdriver = require('selenium-webdriver');
const { Builder } = webdriver;
const phantomjs = require('phantomjs-prebuilt');

// Define your PhantomJS command-line arguments here
const phantomjsArgs = [
  '--load-images=false',
  // Add any other arguments you need here
];

// Set up capabilities with the CLI arguments
const capabilities = webdriver.Capabilities.phantomjs();
capabilities.set('phantomjs.cli.args', phantomjsArgs);

// Set the path to the PhantomJS executable
const phantomjsPath = phantomjs.path;
capabilities.set('phantomjs.binary.path', phantomjsPath);

// Create a WebDriver instance with the configured capabilities
const driver = new Builder()
  .withCapabilities(capabilities)
  .build();

// Example usage: navigate to a webpage
driver.get('https://example.com')
  .then(() => {
    console.log('Page title:', driver.getTitle());
  })
  .catch(error => {
    console.error('Error:', error);
  });

// Don't forget to quit the driver when done
driver.quit();

Here are the changes made to your original code:

Thank you for providing the information and the modified Bash script. Below, I’ll provide a breakdown of the script’s functionality and highlight the changes made for clarity. This will be presented in Markdown format as requested.

Bash Script: Check WiFi Connection and Send Email

This Bash script checks whether the WiFi connection is active and sends an email when it reconnects. Here’s an overview of the script’s key points and improvements:

In order to change the default sender name when sending an email using the mail or mailx command, you can follow these steps. This will allow you to replace the default “root” with your desired name. Please note that these instructions are typically applicable to Unix-like systems such as Linux.

1. Change the Full Name:

   To change the full name associated with your user account, you can use the chfn (change finger) command. Open your terminal and run the following command, replacing "Your Full Name" with the name you want to use as the sender:

Certainly! To update a cron task and customize the email sent from it, you can use the following command with the <CRON COMMAND> replaced by your actual command:

1

<CRON COMMAND> | mail -E -s "Subject" -r "CUSTOM FORM NAME <[email protected]>"

This command will execute <CRON COMMAND> and send the output as an email with the specified subject and sender address.

Here’s a breakdown of the command:

• <CRON COMMAND>: Replace this with the actual command you want to run on a schedule using cron.

When you want to silence the result of a command in a Unix-like shell environment, you can use the > /dev/null or 2> /dev/null redirection techniques, depending on whether you want to suppress standard output (stdout) or standard error (stderr) respectively. Here’s how you can use them:

• To silence standard output (stdout) of a command, use > /dev/null:

  1	command > /dev/null

  This will discard the normal output of the command.

You want to configure for Fail2ban to block SSH public key connection attempts using a custom filter and jail configuration. This setup is designed to identify and block IP addresses that attempt to make SSH key-based connections and fail authentication multiple times. Let’s break down your configuration step by step.

Jail Configuration (jail.local)

In your jail.local configuration, you have defined a custom jail section for SSH key-based authentication:
