I'm trying to get the Network Manager dispatcher to run a script when the network interface comes up or goes down. I want to execute an espeak command when the connection goes up or goes down. I can get it to write to the file /tmp/log but I don't hear any sound from the espeak command even though I can type it directly on the terminal and it works.
The way I test it is by disconnecting my usb network card (this is the only network card I have in the machine)
I've place the executable file in /etc/NetworkManager/dispatcher.d
(it's called 02-ifupdowntest)

See contents of 02-ifupdowntest below:
#!/bin/bash -e
if [ "$2" = "up" ]; then
echo "`date`" > /tmp/log
echo "$1" >> /tmp/log
echo "$2" >> /tmp/log
echo "`/usr/bin/espeak "network up"`"
fi
if [ "$2" = "down" ]; then
echo "$2" >> /tmp/log
echo "`/usr/bin/espeak "network down"`"
fi
exit 0
I'm using Ubuntu 18.04 64bit Linux
espeakcommand seems wrong. – Panki Jan 24 '20 at 12:04/usr/bin/espeak "something"should do the job. You don't need to echo the command. – annahri Jan 27 '20 at 22:11
