Not really. I catch easily stdout, stdin and stderr. My need is to catch
the decimal return code of the command. On UNIX, 0 means success,
anything else means failure.

With os.popen, the close method returns this decimal code:

cmdPipe = os.popen(aCmdLine)
return_code = cmdPipe.close()

With os.popen4, it does not :-(

Thanks Terry.

Another idea ?
