Does apache2 have an equivalent to nginx -T?

Question

I accidentally deleted mysite.conf in /etc/apache2/sites-available (instead of the sym link in /etc/apache2/sites-enabled). The site is still enabled, because I did not reload nor restart apache2 yet. I need to retrieve that config. With nginx, I could simply put nginx -T, which would show me the contents of all loaded .conf files. What can I do with apache2?

Edit: When I try apachectl -S, I don't get all loaded configs. I am looking for the .conf that contains the VirtualHost with port 80. I only get the .conf, that contains the VirtualHost with port 8000.

the tile:warn and tile:notice seems to be in a loop. Every time I rerun apachectl -S the time stamp is of the actual second.

Here is the output of sudo lsof -i -P -n | grep LISTEN to show, that there is indeed a .conf, that contains a VirtualHost with a port of 80:

apache2    7720            root    4u  IPv6 1204364228      0t0  TCP *:80 (LISTEN)

ps -aux shows, that the commands of all the pIDs shown in the list above are: /usr/sbin/apache2 -k start

Also /var/lib/apache2/site/enabled_by_admin contains two empty files: mysite.conf and othersite.conf. However, only the configuration of othersite.conf is shown by apachectl -S

You can use the apachectl -S command or the httpd -S command (depending on your distribution) to print the current running configuration.

This will show you the virtual host configuration syntax for all of the virtual hosts that are currently configured in Apache.
