problem: i want to set up some PD installation stuff at a longer art exhibition. during the night, they might want to shut down the electricity, so it would be cool if they would just have to press the pc power button in the morning and it would autostart the PD patch.

i already figured out how to autostart PD using the session settings in the menu, but without a patch.
the ubuntu documentations only gave me advices how to run a complete programm or how to set up services to run in the background.

any ideas?

Add -open <filename>
to your startup command
You then want to make sure that you have a message to start audio processing and send it a loadbang and everything should run fine.

In case you need to set any audio options here is the listing of pd commandline flags.

I think you only have to add the location of your patch to the command you use to start pd. something like " pd mypatch.pd ".

thank you, guys!
both of you are right, it works with "-open" and without. it's possible to either put the whole path to the file, or to declare a path in PD's file menu and then to just put the filename.
and it's important that the filename has no spaces in it. i still have to get used to this.
wow, that was actually pretty easy! linux rocks!

I could be totally wrong but I think if you use quotes you can use file names with spaces

nope! you're totally right! it works, i just tried.

Or either escape the whitespace (anti-slash in french).
