WordPress command line is a must-to-have if you are running a WordPress site or multisite.
If you know a bit about crontab and bash scripting, you can easily make an automated job that will upgrade all your plugins and themes on a regular basis.
But be aware, some plugins and themes might break, so you might want to have some testing and checking after an upgrade.
We installed it on our server, and it makes our job much easier:
In order to upgrade all plugins:
wp plugin update-all
Upgrade a specific theme:
wp theme update themename
To get more information about a command:
wp help theme status

It’s impressive how WP CLI can streamline backend tasks, especially for managing updates across numerous sites. I’ve found that with very large multisite setups, sometimes a staged rollout of plugin updates per site is safer than a blanket `update-all`, just to catch any unexpected cascading issues. On a related note for managing assets, I’ve found a simple visual tool to be invaluable for quickly organizing and preparing media assets before bulk operations. Slightly off topic, but if you ever deal with AI movie maker, a simple visual tool is what I ended up settling on and it has saved me a fair bit of time.
