Ok, awesome, I got it to work.
(disconnected was spelled wrong and there wasn't some needed spaces in the
code, but it work fine now)
Now to get it to play a file of my choice.
#!/bin/bash
IFACE="ttyUSB0"
SLEEP_TIME="1s"
while true; do
[ "$(nmcli dev status | grep $IFACE | awk '{print $3'})" == "disconnected" ] &&
vlc '/home/grant/Desktop/warningredalert.mp3' || echo "STILL CONNECTED"
sleep $SLEEP_TIME
done
Seems to work great, now to clean up the code a bit (using your example)
#!/bin/bash
IFACE="ttyUSB0"
SLEEP_TIME="1s"
SOUND_FILE='/home/grant/Desktop/warningredalert.mp3'
while true; do
[ "$(nmcli dev status | grep $IFACE | awk '{print $3'})" == "disconnected" ] &&
vlc $SOUND_FILE || echo "STILL CONNECTED"
sleep $SLEEP_TIME
done
And it works great. Since I use VLC for just about everything, it would be nice
if I had a different player to run it in loop.
So since I have gnome mediaplayer already instaled. I replace vlc with
gnome-mplayer and set it to loop (settings menu)
The player just keep the settings so when it's done, it loops again.
Thanks a million guys!
