If you’re a WordPress user or developer, you may have heard about WP-CLI, a powerful command-line interface for managing WordPress sites. But you might not know what it is or how to use it.
In this blog post, we’ll introduce you to WP-CLI, explain why it’s important, and show you how to use it to manage your WordPress site more efficiently.
What is WP-CLI?
WP-CLI is a command-line interface for WordPress, which allows you to manage your WordPress site using the command line rather than the WordPress dashboard. With WP-CLI, you can perform a variety of tasks, such as installing and updating plugins, creating and managing users, importing and exporting data, and much more.
Why use WP-CLI?
There are several reasons why you might want to use WP-CLI. First, it can save you time and effort when managing your WordPress site. With WP-CLI, you can perform tasks more quickly than you could using the WordPress dashboard, especially if you’re working with multiple sites.
Second, WP-CLI allows you to automate certain tasks, which can save you even more time and effort. For example, you can use WP-CLI to update all of the plugins on your site with a single command, rather than having to update each plugin individually through the WordPress dashboard.
Third, WP-CLI is great for developers who prefer working with the command line. If you’re comfortable with the command line, you can use WP-CLI to perform tasks more efficiently than you could using the WordPress dashboard.
How to install WP-CLI
Before you can start using WP-CLI, you’ll need to install it on your system. Fortunately, installing WP-CLI is relatively straightforward. Here’s how to do it:
- First, you’ll need to open a terminal or command prompt on your system. If you’re using a Mac or Linux system, you can open a terminal by pressing Command+Space to open Spotlight, typing “terminal”, and pressing Enter. If you’re using a Windows system, you can open a command prompt by pressing Windows+R to open the Run dialog, typing “cmd”, and pressing Enter.
- Once you have a terminal or command prompt open, you’ll need to install WP-CLI. The easiest way to do this is by using the official WP-CLI installer. To do this, run the following command:
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
This will download the WP-CLI installer to your system.
- Next, you’ll need to make the WP-CLI installer executable. To do this, run the following command:
chmod +x wp-cli.phar
- Finally, you’ll need to move the WP-CLI installer to a directory in your system’s PATH, so that you can run it from anywhere. To do this, run the following command:
sudo mv wp-cli.phar /usr/local/bin/wp
This will move the WP-CLI installer to the /usr/local/bin directory, which is in your system’s PATH.
Congratulations, you’ve now installed WP-CLI on your system!
