:mod:`os` -- basic "operating system" services
==============================================
.. module:: os
:synopsis: basic "operating system" services
The ``os`` module contains functions for filesystem access and ``urandom``.
Pyboard specifics
-----------------
The filesystem on the pyboard has ``/`` as the root directory and the
available physical drives are accessible from here. They are currently:
``/flash`` -- the internal flash filesystem
``/sd`` -- the SD card (if it exists)
.. only:: port_pyboard
On boot up, the current directory is ``/flash`` if no SD card is inserted,
otherwise it is ``/sd``.
.. only:: port_wipy
On boot up, the current directory is ``/flash``.
Functions
---------
.. function:: chdir(path)
Change current directory.
.. function:: getcwd()
Get the current directory.
.. function:: listdir([dir])
With no argument, list the current directory. Otherwise list the given directory.
.. function:: mkdir(path)
Create a new directory.
.. function:: remove(path)
Remove a file.
.. function:: rmdir(path)
Remove a directory.
.. function:: rename(old_path, new_path)
Rename a file.
.. function:: stat(path)
Get the status of a file or directory.
.. function:: sync()
Sync all filesystems.
.. function:: urandom(n)
Return a bytes object with n random bytes, generated by the hardware
random number generator.
.. only:: port_wipy
.. function:: mount(block_device, mount_point, \*, readonly=False)
Mounts a block device (like an ``SD`` object) in the specified mount
point. Example::
os.mount(sd, '/sd')
.. function:: unmount(path)
Unmounts a prevoulsy mounted block device from the given path.
.. function:: mkfs(block_device or path)
Formats the specified path, must be either ``/flash`` or ``/sd``.
A block device can also be passed like an ``SD`` object before
being mounted.
.. function:: dupterm(stream_object)
Duplicate the terminal (the REPL) on the passed stream-like object.
The given object must at least implement the ``.read()`` and ``.write()`` methods.
Constants
---------
.. data:: sep
separation character used in paths
