Have you ever searched where the virtual host of a website is defined in the apache config files? There is a handy option of the apache2ctl script which might help then. When you run the command:

apache2ctl -S

on the shell, you will get a list of all virtual hosts and default servers incl. the line number where it is defined. Example:

~# apache2ctl -S
VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:8080                 is a NameVirtualHost
default server ispconfig.local (/etc/apache2/sites-enabled/000-ispconfig.vhost:10)
port 8080 namevhost ispconfig.local (/etc/apache2/sites-enabled/000-ispconfig.vhost:10)
*:8081                 is a NameVirtualHost
default server ispconfig.local (/etc/apache2/sites-enabled/000-apps.vhost:10)
port 8081 namevhost ispconfig.local (/etc/apache2/sites-enabled/000-apps.vhost:10)
*:80                   is a NameVirtualHost
default server ispconfig.local (/etc/apache2/sites-enabled/000-default:1)
port 80 namevhost ispconfig.local (/etc/apache2/sites-enabled/000-default:1)
port 80 namevhost example.com (/etc/apache2/sites-enabled/example.com.vhost:7)
Syntax OK

Thanks to Planetfox for this tipp.

   If only you could pipe the output from httpd -S. It’s unpipable
   “httpd -S | grep something” would be soooo useful when running a ton of sites but the output just goes to console anyway.

   Charles,

   It’s using standard error, instead of standard out. You can redirect standard error as follows:

   apachectl -S 2> allhosts.txt

   Then you can grep or whatever you need to do with allhosts.txt

   Or if you want to pipe it you can redirect stderr to stdout.

   apachectl -S 2>&1 | grep something

   It saves the step of sending the output to a file.
