wp site list --field=url --path=/var/www/vhosts/example.com/httpdocs | xargs -r -I {} wp cache flush --url={} --path=/var/www/vhosts/example.com/httpdocs

Fetches the URLs of all sites and runs the given command for each one with --url=. Otherwise, many WP-CLI commands only affect the main site of a multisite. The risk depends on the command used.

Note: Test write operations with a single --url= first, otherwise mistakes end up on every site.
