Edit a server command

Can you provide the path to extcommands.xml in the "database subdirectory inside your storage directory" for raspberry pi image?

/var/lib/Repetier-Server/database contains the file on a pi.

Ok found it. Thanks. I was expecting to find whats happening when I press autolevel. I was looking for server command @buttoncommand autolevel.

Where do I find @buttoncommand autolevel?

Button commands are in printer settings->G-Codes->Button Commands and can be edited inside the gui.
