Stanley added the comment: Hmm, I'm not quite following - when you say that the subproccess-ed command should also inherit the redirection, which subprocess command are you referring to, and nested or unnested? I gave it a ran and everything seems to run how I'd expected it, so maybe put another way, what's the expected output from the files and stdout/stderr? ---------- nosy: +slateny _______________________________________ Python tracker https://bugs.python.org/issue44158 _______________________________________
