SOLVED dispatcher script (disable wifi on ethernet) doesnt do anything

Hi guys,

there is a example script in the Arch wiki but it isn't very handy when using a laptop which connects to different docking stations / ethernet dongles which change the name of the "LAN_Interface" frequently.

So here is a better approach I found online but it doesn't do anything for me?

#!/bin/bash

enable_disable_wifi ()
{
    result=$(nmcli dev | grep "ethernet" | grep -w "connected")
    if [ -n "$result" ]; then
        nmcli radio wifi off
#	echo "off"	
    else
        nmcli radio wifi on
#	echo "on"
    fi
}

if [ "$2" = "up" ]; then
    enable_disable_wifi
fi

if [ "$2" = "down" ]; then
    enable_disable_wifi
fi

Output of "nmcli dev | grep "ethernet" | grep -w "connected":

enp52s0f3u1u3u4  ethernet  connected               My Ethernet

The script is in:

/etc/NetworkManager/dispatcher.d/
-rwxr-xr-x 1 root root  342  5. Jun 08:17 70-wifi-wired-exclusive.sh

Any ideas? :S

https://wiki.archlinux.org/title/Networ … plugged_in

Note: You can get a list of interfaces using nmcli. The Ethernet (LAN) interfaces start with en, e.g. enp0s5

[[ "enp0s5" = "en"* ]] || [[ "eth1" = "eth"* ]] && echo foo
[[ "ep0s5" = "en"* ]] || [[ "et1" = "eth"* ]] && echo foo

Thanks but I managed to fix it simply by not running it manually.
It seems the script only triggers/works when the ethernet cable is plugged in or unplugged but not when running the script manually (and changing the status manually as well).

Yes, that's the point of the test inside the script.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
