So first off, you don't need to call them with 'open' from the command
line. You can just run them directly like any other command, like
this:
echo "a b c 1 2 3;" |
/Applications/Pd-extended.app/Contents/Resources/bin/pdsend 3939
The command reads the standard input and sends the data to PD.
Assuming you have a PD patch running with a netrecieve object
listening to port 3939, you can send the same message as above with
this Ruby code:
require 'socket'
hostname = "localhost"
port = 3939
s = TCPSocket.open(hostname, port)
# don't forget the semicolon!
s.puts("a b c 1 2 3;")
s.close()
