Use WP-CLI to Update WordPress core

WP-CLI is an open-source command-line tool that allows you to manage your WordPress website directly from the terminal. With it, you can easily update WordPress to the latest release or to a specific version.

Steps to update WordPress with WP-CLI

SSH to your server, and use this command to check if you have WP-CLI installed:

wp --info

If WP-CLI is not installed, follow this tutorial to install it.

Then use cd command to navigate to the WordPress installation directory, for example:

cd /var/wwww/public/wordpress

Use this command to check for latest update:

wp core check-update

Use this command to update to the latest version:

wp core update

Or if you want to update to the specific version instead of the latest one, use this command (input the version after the --version= parameter):

wp core update --version=6.8.1

The terminal will download and install the WordPress update for you. Once the update is complete, run the following command to update the database:

wp core update-db

And another command to flush the cache:

wp cache flush

Done.
