Tvheadend

Hi,

I try this command (in my nas asustor with tvheadend 4.0.8-15~gaa68090) to have EPG program :

cat tvguide.xml | /volume1/.@plugins/AppCentral/tvheadend/config/epggrab/xmltv.sock
and I have :
nc: bad address '/volume1/.@plugins/AppCentral/tvheadend/config/epggrab/xmltv.sock'

the nc command give me in my system :
BusyBox v1.19.3 (2016-12-14 11:44:12 CST) multi-call binary.

Usage: nc [-iN] [-wN] [-l] [-p PORT] [-f FILE|IPADDR PORT] [-e PROG]

Open a pipe to IP:PORT or FILE

-e PROG    Run PROG after connect
    -l    Listen mode, for inbound connects
        (use -l twice with -e for persistent server)
    -p PORT    Local port
    -w SEC    Timeout for connect
    -i SEC    Delay interval for lines sent
    -f FILE    Use file (ala /dev/ttyS0) instead of network

I try all parameters but nothing is good.
If any person can me help ?
Im' french man, my english not very well; sorry.
