You can use WP-CLI to automate a lot of WordPress related jobs.
Here's a video explanation of this post.
If you run it as root user you'll get this warning.
Error: YIKES! It looks like you're running this as root. You probably meant to run this as the user that your WordPress installation exists under.
If you REALLY mean to run this as root, we won't stop you, but just bear in mind that any code on this site will then have full control of your server, making it quite DANGEROUS.
If you'd like to continue as root, please run this again, adding this flag: --allow-root
If you'd like to run it as the user that this site is under, you can run the following to become the respective user:
sudo -u USER -i -- wp <command>
Even though it's super annoying it is a legit attempt to protect you and your server if you run the tool as root.
The reason is if there's a poorly written plugin it can and possibly damage your system because the root user doesn't have any restrictions at all. If you really know what you're doing you can pass --allow-root parameter but I don't recommend this.
It turns out that you can get the WP-CLI info as root though.

WP-CLI shows you how to run it as a given Linux user but I prefer to use this command instead which I think is more clear.
sudo -H -u YOUR_LINUX_USER bash -c 'wp option get home --path=/var/www/html --skip-plugins --skip-themes'
How do you run wp-cli? Do you switch to that user first and then run WP-CLI commands?
