再也不用擔(dān)心敲錯命令了
相信大家每個人都有敲錯過命令的時候,把python 輸入成 puthon. 手速過快把ls -alh 輸入成 ls a-lh等等等,這時候是不是想拍一下鍵盤說一聲fuck.
有一個同事就開發(fā)了一個thefuck的項(xiàng)目,可糾正先前控制臺命令中的錯誤。讓我們能愉快的工作下去.

Ubuntu安裝vim
忘記加sudo,fuck一下就好了.

thefuck原理
其實(shí)TheFuck的原理就是規(guī)則匹配(正則表達(dá)式),如果找到匹配規(guī)則的命令,則創(chuàng)建一個命令給用戶選擇或直接運(yùn)行。
- cat_dir - 當(dāng)你嘗試cat目錄的時候,用ls替換cat;
- cd_correction – 拼寫檢查和糾正失敗的cd命令;
- cd_mkdir – 在進(jìn)入目錄之前創(chuàng)建目錄;
- cd_parent – 更改 cd.. 為cd ..;
- dry – 修復(fù)類似的重復(fù)問題:git git push;
- fix_alt_space – 用空格字符代替Alt + Space;
