When writing batch scripts, we often need to use the backspace key. But I believe many people don't know how to input the backspace character "" (note that it's a backspace key, not a space) in cmd. I used to just copy it from others' batch scripts.

For this problem, I specifically searched on Baidu and finally found the input method (although it still requires copying): Enter edit in cmd to enter the text editor, then directly press the backspace key on the keyboard, then copy with ctrl+c and paste to the place needed with ctrl+v.
==============================================
Now an experimental second method (the most convenient and quick) is found: Open txt and directly press ctrl+backspace. By the way, my environment is XPSP2.

I'm sorry everyone. After repeated experiments, it's proved that both methods I mentioned are wrong.

The ASCII code of that key seems to be 127. Open Notepad, press alt+127 and then copy.

Hehe, the several methods mentioned above don't get backspace, they just look like black boxes, but they aren't backspace. I've always wanted a quick way to get it, but I still haven't.

　　The proof method is to copy backspace then enter cmd, first move the cursor to the back and then paste to see if the cursor moves forward by one grid.
　　I can guarantee that using the second method in XPSP2 environment definitely types out backspace!

Hmm, indeed, that alt+127 is "del"
But the effect is similar

@echo off

setlocal enabledelayedexpansion

set "退格="

set "var=证明是否是复制退格"

set/p=%var%<nul

for /l %%a in (1 1 20) do set /p=!退格!<nul

set/p=ierythgfdkjghfdsiygsdfghsfdg

pause>nul

The following code uses backspace, and the display result should be a row of English letters, and Chinese characters are not visible.
Try it with your method?
:

@echo off

setlocal enabledelayedexpansion

set "backspace="

set "var=Is the proof copying backspace"

set/p=%var%<nul

for /l %%a in (1 1 20) do set /p=!backspace!<nul

set/p=ierythgfdkjghfdsiygsdfghsfdg

pause>nul

Hehe, learned another trick again, thanks

It's really that without communication, progress is hard to make

Actually, it's also easy to input. Just open any hex editor, such as UE, then switch to hex mode and input a 08.

What the LZ described about inputting Ctrl+BS in Notepad is 0x7F, which is 127, and this should be the DEL key, not the backspace key. Test environment: Chinese XP SP2.

Study! Ctrl+BackSpace is not..

Please provide the specific Chinese text that needs to be translated. Without the Chinese content, I can't perform the translation.

Really learned. I didn't know before.

For this problem, I specifically searched on Baidu and finally found the input method (although copying is also required): Enter edit in cmd to enter the text editor, then directly press the backspace key on the keyboard, then ctrl+c to copy and then ctrl+v to paste to the place you need.

Your first method doesn't work either!

I tried it. If what I said is incorrect, please point it out by the owner:

Pressing backspace under edit doesn't get any visible characters. If there are characters to the left of the cursor, it will only delete the characters to the left.

Also, under edit, you can't directly use ctrl+c to copy to Notepad,

Press ALT+8 in Notepad++ to get the backspace character, then copy it into the text... Pressing ALT+8 in text just performs the operation
