Permissions
-----------

For this, we log in to our team computer. For example:

.. code-block:: console

   $ ssh -p 2020 joerg.faschingbauer@jfasch.bounceme.net

On the team computer, we check our identity, and see that we are all
members of the ``team`` group:

.. code-block:: console

   $ id
   uid=1001(joerg.faschingbauer) gid=1002(joerg.faschingbauer) groups=1002(joerg.faschingbauer),1001(team)

Knowing this, we can now tune permissions of files and directories to
explicitly *share* with other ``team`` members.
