Magnificent app which corrects your previous console command, inspired by a @liamosaur tweet.

The Fuck is too slow? Try experimental instant mode!

Requirements

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

Installation

On OS X you can install The Fuck with Homebrew:

brew install thefuck

On Ubuntu you can install The Fuck with:

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

On FreeBSD you can install The Fuck with:

sudo portsnap fetch update

On other systems you can install The Fuck with pip:

pip install thefuck

Or using an OS package manager (OS X, Ubuntu, Arch).

# You should place this command in your .bash_profile, .bashrc, .zshrc or other startup script:

If you want to run fixed command without confirmation you can use -y option:

fuck -y

If you want to fix commands recursively until success you can use -r option:

fuck -r

Update

pip3 install thefuck --upgrade

  • rm_root – adds --no-preserve-root to rm -rf / command.

Creating your own rules

For adding your own rule you should create your-rule-name.py in ~/.config/thefuck/rules. The rule should contain two functions:

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

Also the rule can contain an optional function

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

and optional enabled_by_default, requires_output and priority variables.

Command has three attributes: script, output and script_parts. Rule shouldn't change Command.

Rules api changed in 3.0: For accessing settings in rule you need to import it with from thefuck.conf import settings. settings is a special object filled with ~/.config/thefuck/settings.py and values from env (see more below).

Simple example of the rule for running script with sudo:

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

More examples of rules, utility functions for rules, app/os-specific helpers.

Settings

The Fuck has a few settings parameters which can be changed in $XDG_CONFIG_HOME/thefuck/settings.py ($XDG_CONFIG_HOME defaults to ~/.config):

  • rules – list of enabled rules, by default thefuck.conf.DEFAULT_RULES;
  • exclude_rules – list of disabled rules, by default [];
  • require_confirmation – requires confirmation before running new command, by default True;
  • wait_command – 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 – 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.

Example of settings.py:

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']

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 – max amount of time in seconds for getting previous command output;
  • THEFUCK_NO_COLORS – disable colored output, true/false;
  • 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 – 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.

For example:

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'

Third-party packages with rules

If you want to make very specific rules or rules, that you don't want to make public, but share with other people. You can create a special package with name thefuck_contrib_* with following structure:

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

And thefuck will find all rules from rules module.

Experimental instant mode

By default The Fuck reruns a previous command and that takes time, in instant mode The Fuck logs output with script and just reads the log.

gif with instant mode

At the moment only Python 3 with bash or zsh is supported.

For enabling instant mode you need to add --enable-experimental-instant-mode to alias initialization in your .bashrc, .bash_profile or .zshrc like:

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