Magento 2 CLI Command Syntax:

The basic syntax for running Magento 2 CLI commands is as follows:

bin/magento <command> [options] [arguments]
  • <command>: The name of the command you want to execute.
  • [options]: Optional flags or options that modify the behavior of the command.
  • [arguments]: Optional arguments that the command may require.

Steps to Create a Custom Magento 2 CLI Command:

To create a custom CLI command in Magento 2, follow these steps:

  1. Create a new module:

    • Create a new module or use an existing one to contain your custom command.

  2. Create a command class:

    • Create a PHP class that extends \Symfony\Component\Console\Command\Command. This class will define your custom command's behavior.

  3. Implement the required methods:

    • In your custom command class, implement the configure() and execute() methods. The configure() method is used to define the command's name, description, and any required options or arguments. The execute() method contains the logic for your command.

  4. Register the command:

    • Register your custom command class in your module's di.xml file to make it available as a CLI command.

  5. Run the command:

    • After registering your command, you can run it using the bin/magento command-line tool.

Here's a simplified example of what your custom command class might look like:

<?php

namespace YourNamespace\YourModule\Console\Command;

use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

class YourCustomCommand extends Command
{
protected function configure()
{
$this->setName('yourmodule:customcommand')
->setDescription('Description of your custom command');
}

protected function execute(InputInterface $input, OutputInterface $output)
{
// Your custom command logic goes here
$output->writeln('Your custom command executed.');
}
}

Remember to replace YourNamespace, YourModule, and customize the command name, description, and logic as needed.

By following these steps, you can create and execute custom CLI commands in Magento 2.
