WP CLI saves WordPress archives every time you setup a new WordPress website. Mostly, actions performed within the WP admin will automatically clear the cache, but you might run into a situation where you need to manually clear it. In that case, you will need to manually clear the cache in 2 ways: WP-CLI command or direct OS bash command.
It basically could be clear with simple command:
$ wp cli cache clear
With showing an output:
Success: Cache cleared.
But sometimes object cache can’t be flushed. In this case you can remove those caches by the following command:
$ rm -rf /root/.wp-cli/cache/* $ rm -rf /home/*/.wp-cli/cache/*
