[PD] restart bash script

[michael strohmann]

Hi !

thanks to Jack and Roman this bash script successfully restarts pd:

#!/bin/bash
sudo puredata /path/to/patch.pd & 
PID1=$!

while true 
do
	if [ ! -d /proc/$PID1 ]
	then
	sudo puredata  /path/to/patch.pd &
	PID1=$!
	fi
sleep 1
done


what i don’t yet get is: what happens if pd is still running but hanging in limbo, frozen in the watchdog loop.
i mean sometimes pd is still running but does not output sound or react to input…
is there a solution to kill and restart pd in such a case?

Thanks !
Michael
