    Interact with system command prompt

    Hi all. I would like to know if there's some python framework able to
    interact with system command prompt (cmd.exe or /bin/sh, depending on
    the system) from python.
    I need something that supports key/path auto completion by pressing TAB
    button and the possibility to use interactive programs like ftp, gpg or
    even vi.
    I would like to write a remote shell application the best featured as
    possible and I'm wondering if Python is able to emulate the
    functionalities of applications like telnet or ssh.

    Thanks in advance for your helping.

      Check out IPython.

          Thank you. It seems to me a powerful tool. I'll try to play with it.

              Uhm... It seems that IPython got some problems:
              http://ipython.scipy.org/doc/manual/node12.html


              In details:

                  Might be. But it could provide some insight into how to solve your problem.

                      Note that these are simply limitations of what has been done out of
                      developer interest, not fundamental ones of design. I'm not in the
                      business of writing system shells, so I (nor anyone else) never implemented
                      full-fledged job control.

                      If you do it and send it in, we'll be happy to include it. And I suspect
                      IPython does a LOT of stuff already that you'll spend a fair amount of time
                      rewriting from scratch, so perhaps helping in to fill in the missing pieces
                      might be a good investment of your time.

                      Cheers,
