  • 0

The WordPress Command Line Interface (WP-CLI) is a powerful tool that allows you to manage WordPress sites directly from the command line, bypassing the need for a graphical interface. It simplifies routine tasks, enhances efficiency, and is especially useful for developers and advanced users managing multiple sites.

This guide will help you understand WP-CLI, its benefits, and how to use it effectively with your hosting plan.


What is WP-CLI?

WP-CLI is an open-source tool that provides a command-line interface for managing WordPress installations. With WP-CLI, you can perform various tasks such as updating plugins, configuring themes, creating posts, and more—directly from your terminal.


Benefits of Using WP-CLI

  • Time-Saving: Automate repetitive tasks like updates, backups, and configurations.
  • Simplified Management: Manage multiple WordPress installations from a single terminal.
  • Efficiency: Perform bulk operations (e.g., activating plugins across all sites in a Multisite setup).
  • Enhanced Control: Access advanced WordPress functionalities without a browser.

Prerequisites for Using WP-CLI

  1. Access to SSH: Ensure your hosting plan supports SSH access.
  2. WP-CLI Installed: Many hosting providers pre-install WP-CLI. If not, you can install it manually.
  3. Basic Command Line Knowledge: Familiarity with terminal commands is beneficial.

Getting Started with WP-CLI

1. Check WP-CLI Installation

After accessing your server via SSH, check if WP-CLI is installed:

wp --info

If installed, this command will display details about WP-CLI, PHP, and the server.

2. Navigate to Your WordPress Directory
Use the `cd` command to move to the directory where your WordPress files are located:
cd /path/to/wordpress
