[issue3548] subprocess.pipe function

[Anh Hai Trinh]

I've written a package which can do this with arbitrary redirection in all subcommands (and some more).

You can, for example, do this:

    >>> Pipe(Sh('echo -n foo >&2', {2: 1}), Sh('cat; echo ERROR >&2', {2: os.devnull})).capture(1).read()
    'foo'

The package is at: http://github.com/aht/pc.py
