问题描述

是否可以在终端中键入空字符?

我想做类似的事情:

this is a sentence (null) test123
解决方案

在Linux中,可以通过按 + 紧跟在终端上,从字面上插入任何特殊字符.由实际的符号. null通常是^@,其中^表示,而@表示在键盘布局上产生的任意组合.

所以我在键盘上执行: + ,然后是 + + ,我得到一个带有显着背景色的^@符号.这意味着它是一个特殊字符,而不仅仅是键入^@.

几年后,不同的终端使用键盘布局实现了一些输入变化,这些布局要求按下才能访问. /p>

  • + ,然后是 + +
  • + ,然后按 + ,释放.
  • + + 后跟 ,释放 + .
  • + 释放并再次按并保持两个,然后按下,最后按下.在某些在 + 上实现特殊输入的终端中可以看到.

Is there a way to type the null character in the terminal?

I would like to do something like:

this is a sentence (null) test123
解决方案

In Linux, any special character can be literally inserted on the terminal by pressing + followed by the actual symbol. null is usually ^@ where ^ stands for and @ for whatever combination on your keyboard layout that produces .

So on my keyboard I do: + followed by ++ and I get a ^@ symbol with a distinguished background color. This means it's a special character and not just ^ and @ typed in.

Edit: Several years later and a few input variations implemented by different terminals using keyboard layouts that require pressing to access .

  • + followed by ++
  • + followed by + without releasing .
  • ++ followed by without releasing +.
  • + release and re-press keeping both + pressed followed by and finally . Seen in some terminals that implement a special input on +.
