在 bash 中，如何清除当前输入? [英] In bash, how does one clear the current input?

问题描述

假设您在 bash 中开始编写如下命令:

Suppose in bash you start writing a command like:

$ rm -rf /foo/bar/really/long/path/here

然后意识到您根本不想执行此操作.有没有办法通过一两次按键清除输入?

and then realize you don't want to execute this after all. Is there a way to clear the input with one or two keystrokes?

我最近一直在做的是在 echo 之前加上引号并将输入括起来 (Ctrl+A, echo ", Ctrl+E, ") 然后按回车键.有没有更快的方法?

What I have been doing lately is prepending echo and enclosing the input in quotes (Ctrl+A, echo ", Ctrl+E, ") then hitting enter. Is there a faster way?

推荐答案

1. 按 Ctrl-U 删除光标前的所有内容.删除的命令将存储到缓冲区中.按 Ctrl-Y 粘贴删除的命令.

1. Press Ctrl-U to delete everything before the cursor. The deleted command will be stored into a buffer. Press Ctrl-Y to paste the deleted command.

(可选:按 End 或 Ctrl-E 先跳到输入的结尾.)

(Optional: Press End or Ctrl-E to jump to the end of the input first.)

或者，按 Ctrl-C 中止您正在输入的内容.

Alternatively, press Ctrl-C to abort what you're typing.
