Hi, I am here again, I would like to know if it's possible to execute the bang object of a pd patch without using graphical environment of pd. I look at pyata, but I was'n able to intall it. I try to start the pd patch from terminal with option -nogui, but I didn't manage to "click" the bang object.

There are some way to do this?
Best regards,

you can start pd with a -nogui startup flag, so there's no gui elements loaded, and then communicate with other programs via the [netsend] and [netreceive] objects.

An important part of Pure Data is the little program called "pdsend". If you open up a port inside your pd patch-- for example, by using

[netreceive 1234]
|
[print]

then you can use pdsend to send messages to pd on that port. From a linux console on the same machine you can send a message llike this:

echo Hello World \; | pdsend 1234 localhost

and it will arrive to the left inlet of netreceive.

There are some more ways to craft a message on the console. See:

But if you're using a remote machine, be careful because anyone who figures out you have that port open can start sending arbitrary messages to your Pd instance and/or listen to what you're sending. Plus the number of people sending messages remotely to/from Pd instances is relatively small so it isn't as hardened as something like ssh.
