QNAP TVHeadend_0.9.8.0_x86_64.qpkg - Fritz Box 6490 cable - where to configure satipdesc.xml (solved)

I read in a few other forum entries like here https://tvheadend.org/d/7733-tvheadend-fritzbox-6660-cable?r=46662#message-46662 that I have open file /etc/init.d/TVHeadend.sh and find a string like ARGS="-f" in order to add the String --satip_xml http://10.0.0.1:49000/satipdesc.xml

The problem is that within TVHeadend.sh on my qnap there is no such string ARGS="-f"!

Where should I add the satipdesc.xml that the tuners can be found?

Thanks in advance!

Solved - now I understood the hint in the other froum entry:

>For me it did not show the tuners in TVHeadend. But after doing this from the QNAP NAS command line:

>vi ./TVHeadend.sh cmdline
I had to type in ./TVHeadend.sh cmdline without vi.
cmd line file gets saved at:

/share/CACHEDEVxyz/.qpkg/TVHeadend/tvh_cmdline

> And put this in the first cmdline:
>--satip_xml http://10.238.238.1:49000/satipdesc.xml > Saved with ESC
