@echo off
for /f "tokens=1 delims=%% " %%a in (222.txt) do echo %%a>>2222.txt
pause
The content in 222.txt is as follows:
0|60|0|100.00%|0.00%|17.32%|14.57%|55.64%|8.14|18.14|0.02|16.35|16.19|83.51|26%
There was an execution error, I don't understand...
At first, I just wanted to remove the % in the file, but the for execution didn't work
I'm sorry, it's because I didn't write my content in enough detail to cause disputes among everyone, , just to explain the problem, I didn't write it in too much detail, sorry

Could the percent sign just not be used as a separator? I also can't make it work in Unix.

One % doesn't work, two % are enough.

The code is incorrect unless you don't want the characters after the first %.

You didn't test it, don't make unfounded conclusions. Who said it's incorrect? I want the following, and this is also correct.
The content of 222.txt is:
0|60|0|100.00%|0.00%|17.32%|14.57%|55.64%|8.14|18.14|0.02|16.35|16.19|83.51|26%

@echo off
for /f "tokens=1 delims=%% " %%a in (222.txt) do echo %%a
pause
Displays: 0|60|0|100.00

@echo off
for /f "tokens=1，２ delims=%% " %%a in (222.txt) do echo %%a %%b
pause
Displays: 0|60|0|100.00　|0.00

@echo off
for /f "tokens=1，２,3,4,5,6 delims=%% " %%a in (222.txt) do echo %%a %%b %%c %%d %%e %%f
pause
Displays:
0|60|0|100.00 |0.00 |17.32 |14.57 |55.64 |8.14|18.14|0.02|16.35|16.19|83.51|26

I don't talk nonsense without testing.
Please try the following code:
@echo off&setlocal enabledelayedexpansion

for /f %%a in (222.txt) do (

            set str=%%a

            set str=!str:%%=!

            >>2222.txt echo !str!

)

pause

　　Just to interject, the code above is not rigorous enough. If there are spaces or horizontal tabs in 222.txt, the for loop will only get the characters before the space. It is recommended to add "delims=".

Thank you, Brother lxmxn. At that time, I was only focused on achieving the effect and indeed didn't consider it comprehensively. Thanks for the reminder!

The result of my test is:
0|60|0|100.00|0.00|17.32|14.57|55.64|8.14|18.14|0.02|16.35|16.19|83.51|26
There is nothing wrong. I don't know where the code you mentioned is wrong. Please clarify where the place you said would have an error is.

　　Re tianzizhi :

　　Make the following content as the content of 222.txt, and try again?


0|60|0|100.00%| 0.00%|17.32%|14 .57%|55.64%|8.14|18.14|0.02|16.35|16.19|83.51|26%

lxmxn, you may have misunderstood. What I'm talking about is ccwan.
Said that my answer on the third floor would be wrong in some places,
『Floor 3』:
One % is not okay, use two %s.
@echo off
for /f "tokens=1 delims=%%" %%a in (222.txt) do echo %%a>>2222.txt
pause
『Floor 4』:
Unless you don't want the characters after the first %, the code is incorrect.

I don't know what he means by the code being incorrect, and then he posted the code you saw. I tested it again, and there's nothing wrong.
For the content in 222.txt that you mentioned, there are spaces, so you need to add delims=.
@echo off&setlocal enabledelayedexpansion
for /f "delims=" %%a in (222.txt) do (
set str=%%a
set str=!str:%%=!
>>2222.txt echo !str!
)
pause
The test result is:
0|60|0|100.00| 0.00|17.32|14 .57|55.64|8.14|18.14|0.02|16.35|16.19|83.51|26
There's nothing wrong either. Still, please let ccwan clarify what he means by the mistake. I want to know.

Hehe,
The content of 222.txt is:

0|60|0|100.00%|0.00%|17.32%|14.57%|55.64%|8.14|18.14|0.02|16.35|16.19|83.51|26% 



@echo off

for /f "tokens=1 delims=%% " %%a in (222.txt) do echo %%a

pause

Displays: 0|60|0|100.00


The result is not what the original poster wanted, of course it's incorrect. The situation at that time was just like that!

　　Oh, it was a misunderstanding. Sorry about that.
