If you have several instances of Pd, it is also doable to do something like :
pd -open yourpatch1.pd & PID1=$! pd -open yourpatch2.pd & PID2=$!
while true do if [ ! -d /proc/$PID1 ] then pd -open yourpatch1.pd & PID1=$! fi if [ ! -d /proc/$PID2 ] then pd -open yourpatch2.pd & PID2=$! fi done

Hello, i wonder if it is possible to setup something on raspberry, so that the puredata-watchdog will restart pd-0.48.0 automatically? where could i look up the mechanics of this, unfortunatly i am not a unix crack…
Are you referring to the pd-watchdog binary, that comes with puredata- core? Is your Raspberry Pi running Raspbian?
From what I understand, the purpose of the pd-watchdog is to pause Pd in regular intervals when running in real-time mode. I think this is measure to prevent Pd from locking up the system. Assume you accidentally trigger an [until] without a stopping mechanism, thanks to pd-watchdog you're still able to move the mouse and quit Pd.
Is your goal to make sure that Pd is running at any time, so that it is started again as soon as it stops? Maybe you can achieve something like this wit a shell script. I haven't tested this, but it might give you an idea how to make it work:
#!/bin/sh
while true do # We start pd and send detach it from the terminal ('&') /usr/bin/pd -open yourpatch &
# we catch pd's process id pdpid=$!
# now let's wait for the process to terminate wait $pdpid
# once pd terminates, we start another iteration # of our while-loop done
I will do something like :
while true do pd -open yourpatch # if pd crash the script continue to "sleep 1" and a new loop start sleep 1 done
