321 If *shell* is ``True``, the specified command will be executed through
322 the shell. This can be useful if you are using Python primarily for the
324 convenient access to other shell features such as shell pipes, filename

452 On Windows with ``shell=True``, the :envvar:`COMSPEC` environment variable
453 specifies the default shell. The only time you need to specify
454 ``shell=True`` on Windows is when the command you wish to execute is built
455 into the shell (e.g. :command:`dir` or :command:`copy`). You do not need
456 ``shell=True`` to run a batch file or console-based executable.

483 is very seldom needed. When ``shell=False``, *executable* replaces the
