快速安装使用

快速安装使用，四步即可：

#Ubuntu/Debian系统
sudo apt update
sudo apt install python3-dev python3-pip
sudo pip3 install thefuck
#编辑bashrc配置文件
vim ~/.bashrc
#在文件尾加入一行给thefuck取别名fuck
eval "$(thefuck --alias fuck)"
#使生效
source ~/.bashrc

#其他#
#修正三条命令前的错误	-	 fuck 3
#新到最新的 thefuck	-	 sudo pip3 install thefuck --upgrade

1. 简介

thefuck 是一个开源的命令行工具，用于自动纠正终端中的错误命令。它通过分析最近执行的命令和错误信息，提供一个或多个可能的正确命令，用户可以选择自动执行或手动确认。

更多示例：

➜ 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 [enter/↑/↓/ctrl+c]
[sudo] password for nvbn:
Reading package lists... Done
...

➜ git push
fatal: The current branch master has no upstream branch.
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 [enter/↑/↓/ctrl+c]
Counting objects: 9, done.
...

2. 安装

#CentOS系统
yum -y update && yum -y install gcc 
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py && yum -y install python-devel
sudo -H pip install thefuck
 
#Ubuntu/Debian系统
sudo apt update
sudo apt install python3-dev python3-pip
sudo pip3 install thefuck

3.配置

#编辑bashrc配置文件
vim ~/.bashrc
#在文件尾加入一行给thefuck取别名fuck
eval "$(thefuck --alias fuck)"
#使生效
source ~/.bashrc

最后使用fuck命令来纠正命令行拼写错误。

4. 补充

• 历史修正

  #thefuck 可以使用历史记录来更正以前的命令。例如，如果你想修正三条命令前的错误
   $ fuck 3
  

• 更新到最新的 thefuck 的方法:

   sudo pip3 install thefuck --upgrade
  

• 自定义部分配置示例

  #thefuck的配置文件位于 ~/.config/thefuck/settings.py。你可以在这里修改一些默认设置，例如：
  #这个参数指定了 thefuck 应用的规则列表。thefuck 会根据这些规则来修正命令错误。如果没有特别指定，thefuck 会使用所有默认的规则
  rules = [<list_of_rules>]
  require_confirmation = True
  wait_command = 3
  

  #例如：
  rules = ['sudo', 'no_command', 'missing_argument']  表示只启用 'sudo'、'no_command' 和 'missing_argument' 这三个规则
  #下列参数指定在修正命令之前是否需要用户确认。如果设置为 True，thefuck 会在执行修正命令之前提示用户确认。如果设置为 False，thefuck 会自动修正并执行命令而不需要用户确认
  require_confirmation = True
  #wait_command = 3：这个参数指定 thefuck 在执行修正命令之前等待的时间（单位：秒）。这是为了给用户提供一个时间窗口来取消修正操作。如果你不需要这个延迟，可以设置为 0
  wait_command = 0
  

  综上示例所述，这些设置帮助你更灵活地控制 thefuck 的行为

  rules = ['sudo', 'no_command', 'missing_argument']
  require_confirmation = True
  wait_command = 3
  

  编写自定义规则

  可以编写自己的规则来处理特定的命令错误。在 ~/.config/thefuck/rules/ 目录中创建一个新的 Python 文件。 示例，创建一个 git_no_branch.py 文件：

  from thefuck.utils import replace_argument, for_app
  from thefuck.specific.git import git_support
  
  @git_support
  def match(command):
      return ('error: src refspec master does not match any' in command.output)
  @git_support
  def get_new_command(command):
     return replace_argument(command.script, 'master', 'main')
