What The F**k

What the F**k

When I first heard about this tool, I laughed for about five minutes and said to myself thats a good joke those guys have played. That is until I actually tried it out for myself and found it to probably be one of the best command line helpers that i've installed onto my machine.

What is it?

According to their readme

The Fuck is a magnificent app, inspired by a @liamosaur tweet, that corrects errors in previous console commands.

Personally i've found this app to be a great help when it comes to messing up my spelling, especially since i've just bought a Dygma Raise and i'm currently getting used to the split keyboard layout.

Installation

On OS X, you can install The Fuck via Homebrew (or via Linuxbrew on Linux):

brew install thefuck

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

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

On FreeBSD, install The Fuck with the following commands:

pkg install thefuck

On ChromeOS, install The Fuck using chromebrew with the following command:

crew install thefuck

On other systems, install The Fuck by using pip:

pip install thefuck

Usage

Lets say you type the following

git brnch

The next thing you are going to see in your terminal is a message asking did you mean

did you mean
	git branch

but now instead of typing the whole thing we can simply say

fuck

this will then give you the previous command corrected but will also give you some other options if it thinks you meant something else. Once you hit enter it will run git branch for you.

thewebuiguy@mbp Desktop % git brnch
git: 'brnch' is not a git command. See 'git --help'.

The most similar command is
	branch
thewebuiguy@mbp Desktop % fuck
git branch [enter/↑/↓/ctrl+c]
