What exactly is the problem with the building's error? I saw that kind of error before.

　　From this code, it seems you are executing in the CMD window. Judging from your overall meaning, you want to first switch to the root directory of drive C and then create a folder, but the first sentence you started with didn't have...

Why do I get no errors when I execute it??? Confused

In fact, there are still bugs when the for is extended to file names:

In the for statement, when executing dir /ad or dir /a-d and using %%~ni to extend to the file name, the FOR statement processing mechanism may be to remove the "." after the last path "\" symbol and the following suffix, and only display the file name;

And if /ad only searches for folders, and there is no "." after the last path "/", it will display the entire last directory name.

There is a flaw in the first command of your code. Suppose you run it on drive D...

But the expansion of %%~ni in the for statement does have a bug. I didn't test it at that time. Later I found that there was a problem with its expansion mechanism.

Thanks to the enthusiastic help of all friends

The purpose of the younger brother is like this. Through the following code

echo.>temp.txt
for /f %%i in ('dir /ad /s /b') do (echo %%~ni|findstr "^*$" && echo %%i >>temp.txt)
for /f %%i in (temp.txt) do del /q %%i\*.*

But it is stuck on findstr

This statement is incorrect. The 'dir' command under CMD can distinguish whether a file is a folder or a file. Otherwise, why are there the two parameters /ad and /a-d for the 'dir' command? If according to your understanding...

Agreed

D:\scripts>for /f %i in ("\123.456") do echo %~ni

D:\scripts>echo 123
123

This is a batch script I found on the forum before

set /p aa=Enter your code:
echo %aa% | findstr "^[a-z][A-Z]*$"||echo ERROR!!!
pause

I remember it seemed to be executable at that time. Now it's actually such an execution result

D:\scripts>set /p aa=Enter your code:
Enter your code:
D:\scripts>echo dfg | findstr "^[a-z][A-Z]*$" || echo ERROR!!!

D:\scripts>set /p aa=Enter your code:
Enter your code:
D:\scripts>echo dfg | findstr "^[a-z][A-Z]*$" || echo ERROR!!!

D:\scripts>set /p aa=Enter your code:
Enter your code:
D:\scripts>echo dfg | findstr "^[a-z][A-Z]*$" || echo ERROR!!!

D:\scripts>set /p aa=Enter your code:
Enter your code:
D:\scripts>echo dfg | findstr "^[a-z][A-Z]*$" || echo ERROR!!!

D:\scripts>set /p aa=Enter your code:
Enter your code:
D:\scripts>echo dfg | findstr "^[a-z][A-Z]*$" || echo ERROR!!!

D:\scripts>set /p aa=Enter your code:
Enter your code:
D:\scripts>echo dfg | findstr "^[a-z][A-Z]*$" || echo ERROR!!!
