Installation [ experimental ]
On Ubuntu and OS X you can install
The Fuck with installation script: wget -O - https://raw.githubusercontent.com/nvbn/thefuck/master/install.sh | sh - && $0Manual installation
Install
The Fuck with pip : sudo pip install thefuckYou should place this command in your
.bash_profile , .bashrc , .zshrc or other startup script: eval "$(thefuck --alias)"
# You can use whatever you want as an alias, like for Mondays:
eval "$(thefuck --alias FUCK)"Changes will be available only in a new shell session. To make them available immediately, run
source ~/.bashrc (or your shell config file like .zshrc ). Update
sudo pip install thefuck --upgradeHow it works
The Fuck tries to match a rule for the previous command, creates a new command using the matched rule and runs it. Rules enabled by default are as follows:
cargo– runscargo buildinstead ofcargo;cargo_no_command– fixes wrongs commands likecargo buid;cd_correction– spellchecks and correct failed cd commands;cd_mkdir– creates directories before cd'ing into them;cd_parent– changescd..tocd ..;composer_not_command– fixes composer command name;cp_omitting_directory– adds-awhen youcpdirectory;cpp11– adds missing-std=c++11tog++orclang++;dirty_untar– fixestar xcommand that untarred in the current directory;dirty_unzip– fixesunzipcommand that unzipped in the current directory;django_south_ghost– adds--delete-ghost-migrationsto failed because ghosts django south migration;django_south_merge– adds--mergeto inconsistent django south migration;docker_not_command– fixes wrong docker commands likedocker tags;dry– fixes repetitions likegit git push;fix_alt_space– replaces Alt+Space with Space character;fix_file– opens a file with an error in your$EDITOR;git_add– fixes "Did you forget to 'git add'?" ;git_branch_delete– changesgit branch -dtogit branch -D;git_branch_list– catchesgit branch listin place ofgit branchand removes created branch;git_checkout– fixes branch name or creates new branch;git_diff_staged– adds--stagedto previousgit diffwith unexpected output;git_fix_stash– fixesgit stashcommands (misspelled subcommand and missingsave);git_not_command– fixes wrong git commands likegit brnch;git_pull– sets upstream before executing previousgit pull;git_pull_clone– clones instead of pulling when the repo does not exist;git_push– adds--set-upstream origin $branchto previous failedgit push;git_push_pull– runsgit pullwhenpushwas rejected;git_stash– stashes you local modifications before rebasing or switching branch;git_two_dashes– adds a missing dash to commands likegit commit -amendorgit rebase -continue;go_run– appends.goextension when compiling/running Go programsgrep_recursive– adds-rwhen you trying togrepdirectory;gulp_not_task– fixes misspelledgulptasks;has_exists_script– prepends./when script/binary exists;heroku_not_command– fixes wrongherokucommands likeheroku log;history– tries to replace command with most similar command from history;java– removes.javaextension when running Java programs;javac– appends missing.javawhen compiling Java files;lein_not_task– fixes wrongleintasks likelein rpl;ls_lah– adds-lahtols;man– changes manual section;man_no_space– fixes man commands without spaces, for examplemandiff;mercurial– fixes wronghgcommands;mkdir_p– adds-pwhen you trying to create directory without parent;mvn_no_command– addsclean packagetomvn;mvn_unknown_lifecycle_phase– fixes misspelled lifecycle phases withmvn;no_command– fixes wrong console commands, for examplevom/vim;no_such_file– creates missing directories withmvandcpcommands;open– prependshttpto address passed toopen;pip_unknown_command– fixes wrongpipcommands, for examplepip instatl/pip install;python_command– prependspythonwhen you trying to run not executable/without./python script;python_execute– appends missing.pywhen executing Python files;quotation_marks– fixes uneven usage of'and"when containing args';rm_dir– adds-rfwhen you trying to remove directory;sed_unterminated_s– adds missing '/' tosed'sscommands;sl_ls– changessltols;ssh_known_hosts– removes host fromknown_hostson warning;sudo– prependssudoto previous command if it failed because of permissions;switch_lang– switches command from your local layout to en;systemctl– correctly orders parameters of confusingsystemctl;test.py– runspy.testinstead oftest.py;touch– creates missing directories before "touching";tsuru_login– runstsuru loginif not authenticated or session expired;tsuru_not_command– fixes wrongtsurucommands liketsuru shell;tmux– fixestmuxcommands;unknown_command– fixes hadoop hdfs-style "unknown command", for example adds missing '-' to the command onhdfs dfs ls;vagrant_up– starts up the vagrant instance;whois– fixeswhoiscommand.

Creating your own rules
For adding your own rule you should create
your-rule-name.py in ~/.thefuck/rules . The rule should contain two functions: match(command: Command) -> bool
get_new_command(command: Command) -> str | list[str]side_effect(old_command: Command, fixed_command: str) -> None enabled_by_default , requires_output and priority variables. Command has three attributes: script , stdout and stderr . 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 ~/.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.stderr.lower()
or 'EACCES' in command.stderr)
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 = TrueSettings
The Fuck has a few settings parameters which can be changed in
~/.thefuck/settings.py : rules– list of enabled rules, by defaultthefuck.conf.DEFAULT_RULES;exclude_rules– list of disabled rules, by default[];require_confirmation– requires confirmation before running new command, by defaultTrue;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 lowerprioritywill be matched first;debug– enables debug output, by defaultFalse.
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 = FalseTHEFUCK_RULES– list of enabled rules, likeDEFAULT_RULES:rm_rootorsudo:no_command;THEFUCK_EXCLUDE_RULES– list of disabled rules, likegit_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, likeno_command=9999:apt_get=100, rule with lowerprioritywill be matched first;THEFUCK_DEBUG– enables debug output,true/false.
