*The Fuck* is a magnificent app, inspired by a
[@liamosaur](https://twitter.com/liamosaur/)
`tweet <https://twitter.com/liamosaur/status/506975850596536320>`__,
that corrects errors in previous console commands.

Is *The Fuck* too slow? `Try the experimental instant
mode! <#experimental-instant-mode>`__

Requirements
------------

-  python (3.4+)
-  pip
-  python-dev

''''''''''''''''''''''''''''''''

Installation
------------

On macOS or Linux, you can install *The Fuck* via
`Homebrew <https://brew.sh/>`__:

.. code:: bash

   brew install thefuck

On Ubuntu / Mint, install *The Fuck* with the following commands:

.. code:: bash

   sudo apt update
   sudo apt install python3-dev python3-pip python3-setuptools
   pip3 install thefuck --user

On FreeBSD, install *The Fuck* with the following commands:

.. code:: bash

   pkg install thefuck

On ChromeOS, install *The Fuck* using
`chromebrew <https://github.com/skycocker/chromebrew>`__ with the
following command:

.. code:: bash

   crew install thefuck

On other systems, install *The Fuck* by using ``pip``:

.. code:: bash

   pip install thefuck

`Alternatively, you may use an OS package manager (OS X, Ubuntu,
Arch). <https://github.com/nvbn/thefuck/wiki/Installation>`__

# It is recommended that you place this command in your
``.bash_profile``, ``.bashrc``, ``.zshrc`` or other startup script:

.. code:: bash

   eval $(thefuck --alias)
   # You can use whatever you want as an alias, like for Mondays:
   eval $(thefuck --alias FUCK)

`Or in your shell config (Bash, Zsh, Fish, Powershell,
tcsh). <https://github.com/nvbn/thefuck/wiki/Shell-aliases>`__

Changes are only available in a new shell session. To make changes
immediately available, run ``source ~/.bashrc`` (or your shell config
file like ``.zshrc``).

To run fixed commands without confirmation, use the ``--yeah`` option
(or just ``-y`` for short, or ``--hard`` if you’re especially
frustrated):

.. code:: bash

   fuck --yeah

To fix commands recursively until succeeding, use the ``-r`` option:

.. code:: bash

   fuck -r

.. _back-to-contents-1:

Updating
--------

.. code:: bash

   pip3 install thefuck --upgrade

**Note: Alias functionality was changed in v1.34 of The Fuck**

Uninstall
---------

To remove *The Fuck*, reverse the installation process: - erase or
comment *thefuck* alias line from your Bash, Zsh, Fish, Powershell,
tcsh, … shell config - use your package manager (brew, pip3, pkg, crew,
pip) to uninstall the binaries

Creating your own rules
-----------------------

To add your own rule, create a file named ``your-rule-name.py`` in
``~/.config/thefuck/rules``. The rule file must contain two functions:

.. code:: python

   match(command: Command) -> bool
   get_new_command(command: Command) -> str | list[str]

Additionally, rules can contain optional functions:

.. code:: python

   side_effect(old_command: Command, fixed_command: str) -> None

Rules can also contain the optional variables ``enabled_by_default``,
``requires_output`` and ``priority``.

``Command`` has three attributes: ``script``, ``output`` and
``script_parts``. Your rule should not change ``Command``.

**Rules api changed in 3.0:** To access a rule’s settings, import it
with ``from thefuck.conf import settings``

``settings`` is a special object assembled from
``~/.config/thefuck/settings.py``, and values from env (`see more
below <#settings>`__).

A simple example rule for running a script with ``sudo``:

.. code:: python

   def match(command):
       return ('permission denied' in command.output.lower()
               or 'EACCES' in command.output)


   def get_new_command(command):
       return 'sudo {}'.format(command.script)

   # Optional:
   enabled_by_default = True

   def side_effect(command, fixed_command):
       subprocess.call('chmod 777 .', shell=True)

   priority = 1000  # Lower first, default is 1000

   requires_output = True

Settings
--------

Several *The Fuck* parameters can be changed in the file
``$XDG_CONFIG_HOME/thefuck/settings.py`` (``$XDG_CONFIG_HOME`` defaults
to ``~/.config``):

-  ``rules`` – list of enabled rules, by default
   ``thefuck.const.DEFAULT_RULES``;
-  ``exclude_rules`` – list of disabled rules, by default ``[]``;
-  ``require_confirmation`` – requires confirmation before running new
   command, by default ``True``;
-  ``wait_command`` – the max amount of time in seconds for getting
   previous command output;
-  ``no_colors`` – disable colored output;
-  ``priority`` – dict with rules priorities, rule with lower
   ``priority`` will be matched first;
-  ``debug`` – enables debug output, by default ``False``;
-  ``history_limit`` – the numeric value of how many history commands
   will be scanned, like ``2000``;
-  ``alter_history`` – push fixed command to history, by default
   ``True``;
-  ``wait_slow_command`` – max amount of time in seconds for getting
   previous command output if it in ``slow_commands`` list;
-  ``slow_commands`` – list of slow commands;
-  ``num_close_matches`` – the maximum number of close matches to
   suggest, by default ``3``.
-  ``excluded_search_path_prefixes`` – path prefixes to ignore when
   searching for commands, by default ``[]``.

An example of ``settings.py``:

.. code:: python

   rules = ['sudo', 'no_command']
   exclude_rules = ['git_push']
   require_confirmation = True
   wait_command = 10
   no_colors = False
   priority = {'sudo': 100, 'no_command': 9999}
   debug = False
   history_limit = 9999
   wait_slow_command = 20
   slow_commands = ['react-native', 'gradle']
   num_close_matches = 5

Or via environment variables:

-  ``THEFUCK_RULES`` – list of enabled rules, like
   ``DEFAULT_RULES:rm_root`` or ``sudo:no_command``;
-  ``THEFUCK_EXCLUDE_RULES`` – list of disabled rules, like
   ``git_pull:git_push``;
-  ``THEFUCK_REQUIRE_CONFIRMATION`` – require confirmation before
   running new command, ``true/false``;
-  ``THEFUCK_WAIT_COMMAND`` – the max amount of time in seconds for
   getting previous command output;

-  ``THEFUCK_PRIORITY`` – priority of the rules, like
   ``no_command=9999:apt_get=100``, rule with lower ``priority`` will be
   matched first;
-  ``THEFUCK_DEBUG`` – enables debug output, ``true/false``;
-  ``THEFUCK_HISTORY_LIMIT`` – how many history commands will be
   scanned, like ``2000``;
-  ``THEFUCK_ALTER_HISTORY`` – push fixed command to history
   ``true/false``;
-  ``THEFUCK_WAIT_SLOW_COMMAND`` – the max amount of time in seconds for
   getting previous command output if it in ``slow_commands`` list;
-  ``THEFUCK_SLOW_COMMANDS`` – list of slow commands, like
   ``lein:gradle``;
-  ``THEFUCK_NUM_CLOSE_MATCHES`` – the maximum number of close matches
   to suggest, like ``5``.
-  ``THEFUCK_EXCLUDED_SEARCH_PATH_PREFIXES`` – path prefixes to ignore
   when searching for commands, by default ``[]``.

For example:

.. code:: bash

   export THEFUCK_RULES='sudo:no_command'
   export THEFUCK_EXCLUDE_RULES='git_pull:git_push'
   export THEFUCK_REQUIRE_CONFIRMATION='true'
   export THEFUCK_WAIT_COMMAND=10
   export THEFUCK_NO_COLORS='false'
   export THEFUCK_PRIORITY='no_command=9999:apt_get=100'
   export THEFUCK_HISTORY_LIMIT='2000'
   export THEFUCK_NUM_CLOSE_MATCHES='5'

Third-party packages with rules
-------------------------------

If you’d like to make a specific set of non-public rules, but would
still like to share them with others, create a package named
``thefuck_contrib_*`` with the following structure:

::

   thefuck_contrib_foo
     thefuck_contrib_foo
       rules
         __init__.py
         *third-party rules*
       __init__.py
       *third-party-utils*
     setup.py

*The Fuck* will find rules located in the ``rules`` module.

Experimental instant mode
-------------------------

The default behavior of *The Fuck* requires time to re-run previous
commands. When in instant mode, *The Fuck* saves time by logging output
with `script <https://en.wikipedia.org/wiki/Script_(Unix)>`__, then
reading the log.

|gif with instant mode|

Currently, instant mode only supports Python 3 with bash or zsh. zsh’s
autocorrect function also needs to be disabled in order for thefuck to
work properly.

To enable instant mode, add ``--enable-experimental-instant-mode`` to
the alias initialization in ``.bashrc``, ``.bash_profile`` or
``.zshrc``.

For example:

.. code:: bash

   eval $(thefuck --alias --enable-experimental-instant-mode)
