hey,
I've tried Ivica suggestion, but it didn't work.
Jonathan strategy works good. What I do now, is to send a message
[echo "env DISPLAY=:0 my-script.sh" | at now(
This runs the whole script, and not only the pd patch, under the at daemon (as Jonhatan said previously), and this way I can kill the parent Pd instance. Works like a charm.
Thanks for your prompt responses!
