Description
***********
.. _`Logging`:
Logging
=======
Console logging
~~~~~~~~~~~~~~~
pip offers :ref:`-v, --verbose <--verbose>` and :ref:`-q, --quiet <--quiet>`
to control the console log level. By default, some messages (error and warnings)
are colored in the terminal. If you want to suppress the colored output use
:ref:`--no-color <--no-color>`.
.. _`FileLogging`:
File logging
~~~~~~~~~~~~
pip offers the :ref:`--log <--log>` option for specifying a file where a maximum
verbosity log will be kept. This option is empty by default. This log appends
to previous logging.
Like all pip options, ``--log`` can also be set as an environment variable, or
placed into the pip config file. See the :doc:`../topics/configuration` section.
.. _`exists-action`:
--exists-action option
======================
This option specifies default behavior when path already exists.
Possible cases: downloading files or checking out repositories for installation,
creating archives. If ``--exists-action`` is not defined, pip will prompt
when decision is needed.
*(s)witch*
Only relevant to VCS checkout. Attempt to switch the checkout
to the appropriate URL and/or revision.
*(i)gnore*
Abort current operation (e.g. don't copy file, don't create archive,
don't modify a checkout).
*(w)ipe*
Delete the file or VCS checkout before trying to create, download, or checkout a new one.
*(b)ackup*
Rename the file or checkout to ``{name}{'.bak' * n}``, where n is some number
of ``.bak`` extensions, such that the file didn't exist at some point.
So the most recent backup will be the one with the largest number after ``.bak``.
*(a)bort*
Abort pip and return non-zero exit status.
