title: Clear cache in Symfony: `cache:clear` or `rm -rf`?
body: <p>Which is the difference between <code>./bin/console cache:clear --env=prod</code> and <code>rm -rf var/cache/prod/*</code>? Console command is very slow. Bash command is fast. So, ... why use <code>cache:clear</code> instead of <code>rm</code>?</p>
