Hi,
Is there a way to track external processes launched by python on the
Mac? I am using subprocess module to launch the process.
Thanks

If using Python 2.3/2.4, you can use os.wait().
If using Python 2.5, there is also have os.wait3() and os.wait4().
See the operating system manual pages for the difference. Ie.,
man wait4

I'm having a slight problem using wait3 or wait4. I want monitor a
launched process and get its resource usage information. When I call
os.wait4 with the pid the first time the call returns successfully but
the second time around I get a OSError with "No child processes"
error. I have tried using WCONTINUED, WNOHANG and WUNTRACED options.
