如何快速删除已经在控制台输入的shell命令？ [关闭]

Question

有时，我会在我的控制台中输入一些 shell 命令，然后再决定不执行它。例如，我在控制台终端中输入以下内容：

sudo rm -r /   # not yet committed! Thank God

好吧，我意识到这有点愚蠢，并决定在真正执行之前删除。

但是，我很懒，我不想按 delete 并等待退格光标。事实上，这种情况对我来说是很正常的。

我想用尽可能少的键盘按下来快速删除 shell 命令。有什么解决办法吗？

谢谢~

Ctrl+u 和 Ctrl+k 是您要查找的内容：

 Ctrl + k    # Cut the Line after the cursor to the clipboard.
 Ctrl + u    # Cut/delete the Line before the cursor to the clipboard.

您可能想尝试的其他常用快捷键：

 Ctrl + w    # Cut the Word before the cursor to the clipboard.
 Ctrl + y    # Paste the last thing to be cut (yank)
 Ctrl + a    # Go to the beginning of the line (Home)
 Ctrl + e    # Go to the End of the line (End)
 Alt + b     # Back (left) one word
 Alt + f     # Forward (right) one word
 Ctrl + f    # Forward one character
 Ctrl + b    # Backward one character
 Alt + d     # Delete the Word after the cursor.
 Ctrl + d    # Delete character under the cursor
 Ctrl + h    # Delete character before the cursor (Backspace)

和往常一样，我建议你去Bash Keyboard Shortcuts 学习更高级的 Bash 技能。
