    # Development paths
    export PATH="$HOME/.local/bin:$PATH"
    export PATH="$HOME/bin:$PATH"

.. note::

    **DevOps Tip**: Customize your terminal for efficiency. A well-configured shell can significantly speed up daily tasks and reduce errors.

``TheFuck`` is a magnificent app that corrects errors in previous console commands.

.. code-block:: bash

    # create Python environment
    python3 -m venv venv

    # source Python environment
    . venv/bin/activate

    # install thefuck python library
    pip install thefuck

Update user profile ``.bashrc``, ``bash_profile`` or ``.profile``

.. code-block:: bash

    eval $(thefuck --alias FUCK)

===========================
Run sudo without a password
===========================

Update the ``/etc/sudoers`` file:

.. code-block:: bash

    %sudo   ALL=(ALL:ALL) ALL

to

.. code-block:: bash

    %sudo   ALL=(ALL:ALL) NOPASSWD:ALL
