Permissions and ownership
^^^^^^^^^^^^^^^^^^^^^^^^^
.. method:: Path.owner(*, follow_symlinks=True)
Return the name of the user owning the file. :exc:`KeyError` is raised
if the file's user identifier (UID) isn't found in the system database.
This method normally follows symlinks; to get the owner of the symlink, add
the argument ``follow_symlinks=False``.
.. versionchanged:: 3.13
Raises :exc:`UnsupportedOperation` if the :mod:`pwd` module is not
available. In earlier versions, :exc:`NotImplementedError` was raised.
.. versionchanged:: 3.13
The *follow_symlinks* parameter was added.
.. method:: Path.group(*, follow_symlinks=True)
Return the name of the group owning the file. :exc:`KeyError` is raised
if the file's group identifier (GID) isn't found in the system database.
This method normally follows symlinks; to get the group of the symlink, add
the argument ``follow_symlinks=False``.
.. versionchanged:: 3.13
Raises :exc:`UnsupportedOperation` if the :mod:`grp` module is not
available. In earlier versions, :exc:`NotImplementedError` was raised.
.. versionchanged:: 3.13
The *follow_symlinks* parameter was added.
.. method:: Path.chmod(mode, *, follow_symlinks=True)
Change the file mode and permissions, like :func:`os.chmod`.
This method normally follows symlinks. Some Unix flavours support changing
permissions on the symlink itself; on these platforms you may add the
argument ``follow_symlinks=False``, or use :meth:`~Path.lchmod`.
::
>>> p = Path('setup.py')
>>> p.stat().st_mode
33277
>>> p.chmod(0o444)
>>> p.stat().st_mode
33060
.. versionchanged:: 3.10
The *follow_symlinks* parameter was added.
.. method:: Path.lchmod(mode)
Like :meth:`Path.chmod` but, if the path points to a symbolic link, the
symbolic link's mode is changed rather than its target's.
