Sending commands from one xterm window to another with Python

Question

So I have a Python app that starts different xterm windows and in one window after the operation is finished it asks the user "Do you want to use these settings? y/n". How can I send y to that xterm window, so that the user doesn't needs to type anything. Thanks

If you are on linux (kde) and you just want to control the xterms by sending commands between them, you could try using dcop:

• http://www.linuxjournal.com/content/start-and-control-konsole-dcop
• http://www.riverbankcomputing.co.uk/static/Docs/PyKDE3/dcopext.html

Otherwise you would need to actually use an inter-process communication (IPC) method between the two scripts as opposed to controlling the terminals:

• http://docs.python.org/library/xmlrpclib.html
• http://docs.python.org/library/ipc.html
• Some other IPC or RPC library
• Simply listen on a basic socket and wait for ANYTHING. And then from the other app open a socket and write SOMETHING to signal.

Or at a very very basic level, you could have one script wait on file output from the other. So once your first xterm finishes, it could write a file that the other script sees.

These are all varying difficulties of solutions.
