Hi all,

I'm having an issue with environment variables and spawned commands.
Specifically, I'm using "eval `ssh-agent`" and "ssh-add". My
question is, how do I force the environmental variables set by one
'popen' or 'pexpect' to propagate throughout the entire Python
session so that any commands called will see those env variables?

Regards,
Michael

A process's environment must be inherited from its parent, or set by
the process itself. Child processes can't affect their parent
process's environment. (This is the way it works in Unix, it's not
specific to Python.)
