Magnificent app which corrects your previous console command, inspired by a @liamosaur tweet.
Few examples:
➜ apt-get install vim
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
➜ fuck
sudo apt-get install vim

To push the current branch and set the remote as upstream, use
git push --set-upstream origin master
➜ fuck
git push --set-upstream origin master
Counting objects: 9, done.
...➜ puthon

Command 'python' from package 'python-minimal' (main)
Command 'python' from package 'python3' (main)
zsh: command not found: puthon

Python 3.4.2 (default, Oct 8 2014, 13:08:17)

Install The Fuck with pip:
sudo pip install thefuckOr using an OS package manager (OS X, Ubuntu, Arch).
And add to .bashrc or .zshrc or .bash_profile(for OSX):
alias fuck='eval $(thefuck $(fc -ln -1))'
# You can use whatever you want as an alias, like for Mondays:
alias FUCK='fuck'On in your shell config (Bash, Zsh, Fish, Powershell).
Changes will be available only in a new shell session.
sudo pip install thefuck --upgradeThe Fuck tries to match rule for the previous command, create new command using matched rule and run it. Rules enabled by default:
brew_unknown_command– fixes wrong brew commands, for examplebrew docto/brew doctor;cd_parent– changescd..tocd ..;cd_mkdir– creates directories before cd'ing into them;cp_omitting_directory– adds-awhen youcpdirectory;fix_alt_space– replaces Alt+Space with Space character;git_no_command– fixes wrong git commands likegit brnch;git_push– adds--set-upstream origin $branchto previous failedgit push;has_exists_script– prepends./when script/binary exists;lein_not_task– fixes wrongleintasks likelein rpl;mkdir_p– adds-pwhen you trying to create directory without parent;no_command– fixes wrong console commands, for examplevom/vim;pip_unknown_command– fixes wrong pip commands, for examplepip instatl/pip install;python_command– prependspythonwhen you trying to run not executable/without./python script;sl_ls– changessltols;rm_dir– adds-rfwhen you trying to remove directory;ssh_known_hosts– removes host fromknown_hostson warning;sudo– prependssudoto previous command if it failed because of permissions;switch_layout– switches command from your local layout to en.
Bundled, but not enabled by default:
ls_lah– adds -lah to ls;rm_root– adds--no-preserve-roottorm -rf /command.
For adding your own rule you should create your-rule-name.py
in ~/.thefuck/rules. Rule should contain two functions:
match(command: Command, settings: Settings) -> bool
and get_new_command(command: Command, settings: Settings) -> str.
Command has three attributes: script, stdout and stderr.
Settings is a special object filled with ~/.thefuck/settings.py and values from env, more.
Simple example of the rule for running script with sudo:
def match(command, settings):
return ('permission denied' in command.stderr.lower()
or 'EACCES' in command.stderr)
def get_new_command(command, settings):
return 'sudo {}'.format(command.script)More examples of rules, utility functions for rules.
The Fuck has a few settings parameters, they can be changed in ~/.thefuck/settings.py:
rules– list of enabled rules, by defaultthefuck.conf.DEFAULT_RULES;require_confirmation– require confirmation before running new command, by defaultFalse;wait_command– max amount of time in seconds for getting previous command output;no_colors– disable colored output.
Or via environment variables:
THEFUCK_RULES– list of enabled rules, likeDEFAULT_RULES:rm_rootorsudo:no_command;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.
