=================================================
Shared-directory for users to "publish" Notebooks
=================================================
One way for users to share or "publish" Notebooks in a JupyterHub environment
is to create a shared directory. Any user can create files in the directory,
but only the creator may edit that file afterwards.
For instance, in a Hub with three users, User A develops a Notebook in their
`/home` directory. When it is ready to share, User A copies it to the
`shared` directory. At that time, User B and User C can see User A's
Notebook and run it themselves (or view it in a Dashboard layout
such as `voila` or `panel` if that is running in the Hub), but User B
and User C cannot edit the Notebook. Only User A can make changes.
#. **Log** in to your JupyterHub as an **administrator user**.
#. **Create a terminal session** with your JupyterHub interface.

#. **Create a folder** where your data will live. We recommend placing shared
data in ``/srv``. The following command creates a directory ``/srv/scratch``
.. code-block:: bash
sudo mkdir -p /srv/scratch
#. **Change group ownership** of the new folder
.. code-block:: bash
sudo chown root:jupyterhub-users /srv/scratch
#. **Change default permissions to use group**. The default permissions for new
sub-directories uses the global umask (``drwxr-sr-x``), the ``chmod g+s`` tells
new files to use the default permissions for the group ``jupyterhub-users``
(``rw-r--r--``)
.. code-block:: bash
sudo chmod 777 /srv/scratch
sudo chmod g+s /srv/scratch
#. **Create a symbolic link** to the scratch folder in users home directories
.. code-block:: bash
sudo ln -s /srv/scratch /etc/skel/scratch
