In batch processing, you want to use "\－/" to represent a progress status, as if the "－" is rolling. How to achieve this?

Do you mean that DOS commands are generally executed while displaying progress?

@echo off
set str=\－/－
setlocal enabledelayedexpansion
:test
for /l %%i in (-1 1 3) do (
set /p=!str:~%%i,1!<nul
ping /n 2 127.1>nul)
cls
goto :test
pause>nul

Can this code complete the task? If the delay of ping /n 2 127.1 is too long (about 2 seconds), please use other methods.

It's very similar to the processing of early compression software, wonderful～:) Add points to youxi01～:)

I'll also do one:

@echo off

setlocal enabledelayedexpansion

set b=\－/－

:b

for /l %%i in (0,1,32) do call :a %%i

cls

goto :b

:a

set/a a=%1%%4

set/p=!b:~%a%,1!<nul

ping/n 2 127.1>nul

goto :eof

Second one:

@echo off

setlocal enabledelayedexpansion

set b=\－/－

:b

for /l %%i in (0,1,3) do (

echo !b:~%%i,1!

ping /n 2 127.1>nul

cls)

goto b

I don't think the original poster meant that. Don't you see that the three symbols /\- combine to form an asterisk? It's estimated that the effect he wants is a rotating effect. If it's a rotating effect, Photoshop processing can't achieve it...

So the original poster wanted a fun animation~ : )
The rotating effect can still be achieved. I think there's nothing that can't be done : )
Not only rotation, but also word processing, inserting characters, modifying... : ) (Need to use ASCII code special control characters : )

Added a backspace function based on the code of moderator qwe1234567兄~ : )



====================== Note: Please don't directly use the method of COPY CON filename.bat to COPY,
====================== Because the following code has special control characters, direct copy won't copy properly.
====================== Simple method: COPY to Windows Notepad, then save as a batch file, then execute.

@echo off

rem qwe1234567 character animation



setlocal enabledelayedexpansion

set b=\-/-

set 速度=2



rem ASCII code 08 is the backspace special control character

set 退格=





:b

for /l %%i in (0,1,200) do call :a %%i

goto :b

:a

set/a a=%1%%4

set/p=!b:~%a%,1!<nul

ping/n %速度% 127.1>nul

set/p=%退格%<nul

goto :eof

"The rotating effect can't be achieved with P processing", it's achieved, hehehe...

You must not have tried it; it's definitely an effect of spinning (in place)!

LZ: "In batch processing, I want to use "\－/" to represent a progress status, it seems like the "-" is rolling", absolutely this kind of effect:)

After each character is displayed, it moves back one space, and then displays again,
(many command-line software prompts are based on this principle!)
In this way, due to the speed and the visual difference of people, an animation effect (similar to spinning) will be produced,
the same as the processing effect animation of early compression software.

Wait, I copied the code wrong, there are several here, I got confused, but the spin effect really works, wait a minute.

Wait,...... I looked again, it's not that I copied wrong!

You must have directly used COPY CON filename.bat in the CMD SHELL to copy the above code,!

So, the "backspace" there = what I put later is the special control character for backspace,
So, when you copy, it actually generates the backspace key, and the backspace symbol here you can't copy.


(You directly copy to Notepad and then save it, it's fine!)
(Originally, when copying the above content directly with copy con filename.bat, the system translated that backspace character as really backspacing by two spaces, causing the variable assignment statement to be incomplete)

Apologize to 9527, it was originally this reason, haha......

Direct download, batch animation code for rotating in place.

Brother, I'm not very smart. Can you tell me:

rem The ASCII code 08 is the backspace special control character
set 退格=

How is the backspace obtained here?

) First method:

Using the ECIT.COM editor built into MS-DOS (also available in WINDOWS CMD SHELL) to enter special control characters.

Enter EDIT.COM, press the CTRL+P combination key, and then you can enter special characters:
For example: The ASCII code of the backspace key (to move the cursor to the left) is 08,
Then you can press ALT+08 (hold down the ALT key, then press the 0 and 8 keys on the right small keyboard, release the ALT key after both are entered.
Note: CTRL+P is only effective once. If you enter the second control character, you have to press CTRL+P again


) Second method: Get it with Debug

) For special control characters like backspace, if you enter ALT+08 directly on the command line, it will "execute" immediately, which is equivalent to you pressing the backspace and deleting the content on the left.

So, it is more convenient to enter it indirectly in edit.com or other ways.

) For 07 (ringing bell), you can enter GTRL+G or ALT+07 on the command line.

) For other control characters, refer to the ASCII code table

Many thanks

3, Use VBS:

createobject("scripting.filesystemobject").opentextfile("tmp.txt",2,true).write chr(8)

Regarding the problem of this topic, actually, it was mentioned in an early reprinted post in this section ("In-depth Exploration of Windows Script Technology"). Now it seems that relatively few friends have understood it.
