Hi,
I have added following condition but its not working:
MYDEV='eth0'
if [ "$ACTION" = "pressed" -a "$BUTTON" = "BUT_2" ] && {
devstatus "$MYDEV" | grep '"up": true' && {
echo "255" >
/sys/devices/platform/leds-gpio/leds/db120:green:status/brightness
}
}
fi
Am i doing any mistake or need to change anything
Regards,
John
