This command is a hub to the most used command within |qp|. The power
of the :ref:`qpsh` shell is the auto-completion that comes when the
:kbd:`<Tab>` key is pressed with the :ref:`qp` command.
EZFIO access
------------
.. option:: set_file
.. code:: bash
qp set_file EZFIO_DIR
Sets the current |EZFIO| directory. All the following instruction will be
relative to this directory.
This command is equivalent to :command:`ezfio set_file EZFIO_DIR`.
.. option:: unset_file
.. code:: bash
qp unset_file
Unsets the current |EZFIO| directory.
This command is equivalent to :command:`ezfio unset_file`.
.. option:: has
.. code:: bash
qp has <module> <parameter>
If the `<module>/<parameter>` is set in the |EZFIO| directory, returns 1.
Otherwise returns 0.
This command is equivalent to :command:`ezfio has <module> <parameter>`.
.. option:: get
.. code:: bash
qp get <module> <parameter>

This command is equivalent to :command:`ezfio get <module> <parameter>`.
.. option:: set

the command line it is read from the standard input.
This command is equivalent to
:command:`ezfio set <module> <parameter> [<value>]`.
Running programs
----------------
.. option:: run
.. code:: bash
qp (run|srun|mpirun) [options] <program>

Getting help
------------
.. option:: man
.. code:: bash
qp man (<program>|<qp_command>)
Displays a man page for a |qp| program or a |qp| command.

.. option:: convert_output_to_ezfio
:command:`qp convert_output_to_ezfio` : runs :ref:`qp_convert_output_to_ezfio`
.. option:: create_ezfio
:command:`qp create_ezfio` : runs :ref:`qp_create_ezfio`
.. option:: plugins
:command:`qp plugins` : runs :ref:`qp_plugins`
