如何快速删除已在控制台中输入的shell命令？

Question

有时，在我决定不执行它之前，我会在控制台中输入一些shell命令。例如，我在控制台终端中键入以下内容：

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

嗯，我意识到它有点愚蠢，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。事实是，这种情况在某种程度上对我来说是正常的。

我想用尽可能少的键盘按下来快速删除shell命令。有没有解决方案？

感谢〜

您正在寻找

Ctrl+u和Ctrl+k：

 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方式：

 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。
