We probably need more information. What do you mean by "send
commands"? (What was your work flow if you could give the command
name to Popen?)
There are ways under Windows to attach to a running process and do
things to it. Look up "CreateRemoteThread". There's a way to
do this under Linux, too. See
"http://www.codeproject.com/KB/DLL/code_injection.aspx";.
It is very unlikely that a Python programmer would use either of
these. The original poster needs to express more clearly what
they really want to do. I suspect they want to create a server
that client programs can talk to. There are good ways to do that,
both on the same machine and across a network.
