I can not find the directory to grabber

Hi. Sorry for the translation.
I have a tvheadend installed on an android that connects to xbmc.
I want to add the grabber xmltv but I do not have the usr / bin directory. Is there any way to know what that directory would be from the terminal?

By SSH I can run for example: stop tvheadend, start tvheadend and it works
I also added the picons with this route to the SD: file: ///storage/sdcard1/logos/%C.png

In the image tvheadend appears as a file.
