Redirect stderr to stdout on exec-ed process from python?

Question

In a bash script, I can write:

exec 2>&1
exec someprog

And the stderr output of someprog would be redirected to stdout.

Is there any way to do a similar thing using python's os.exec* functions?

This doesn't have to be portable, just work on Linux.

Answer 1

You could use the subprocess module instead of os.exec*:

subuprocess.call(['prog', 'param'], stderr=subprocess.STDOUT)

Answer 2

os.dup2(1, 2)
