The "--apache" flag is specifying that the Certbot tool should use the Apache plugin to automatically configure SSL settings for the web server.

The "--domain" flag is used to specify the domain or subdomain for which the SSL/TLS certificates should be generated and installed. In this case, the "${subdomain-example-com}" is a placeholder that should be replaced with the actual subdomain you want to generate the certificate for.

Overall, the command is executing Certbot with the Apache plugin to obtain an SSL/TLS certificate for a specific domain or subdomain, and if successful, configure Apache to use the certificate for secure HTTPS connections.
