China DOS Union

Not knowing programming and not being very familiar with DOS batch processing. It's really difficult to write a script. Now I encounter a new problem:
I now want to get the last part of the file name containing the absolute path. How to write in batch processing?
For example: a:\c\E\b.txt (the path length is not fixed, there may be many layers of directories), now I want to create a variable, let the value of this variable be b.txt, how to solve it with batch processing?

@echo off

    set file=c:\abc\efg\xxx.xxx

    call :Print "%file%"

pause

goto :eof



:Print

    echo %~nx1

goto :eof

The code is written directly in the reply, not tested...

Thanks! This is exactly the effect I want!

The code of 3742668 can be simplified:

@echo off

set file=c:\abc\efg\xxx.xxx

for /f "delims=" %%i in ("%file%") do echo %%~nxi

pause

I found a small bug and fixed it, which can adapt to the situation where the path name has spaces.

The learning atmosphere here is really good, I'm going to study hard.

That's really nice!

Moderator 3742668 converts the file path into the variable %1 using call, preparing for expanding to the file name and suffix.

Moderator namejm directly uses for to convert the file path into replaceable variables, then performs expansion.

```
@echo off
set file=x:\xxx\xxx\xxx.xxx
set file=%file:\=\\%
wmic datafile where "caption='%file%'" get filename,extension
pause

@echo off
set file=x:\xxx\xxx\xxx.xxx
set str=%file%
:loop
set str=%str:*\=%
echo %str% | findstr /i "\\" >nul && goto loop
echo %file% ---^> %str%
pause
The above codes have not been tested...
```

Everyone is very capable, or here the atmosphere is good, thanks everyone

The second paragraph of code at 7F is probably the most general. By expanding it, you can obtain the folder names at a specified level.

```
@echo off
set file=x:\xxx\xxx\xxx.xxx
set file=%file:\=" "%
call :Get "%file%"
pause
goto :eof

:Get
for %%i in (%*) do echo %%~i
goto :eof
```
General use should still be the above.

The 10F version cannot correctly handle paths with spaces, while the 7F version can; if you want to get the folder name of a specified level, the 10F version is a bit more concise, and the 7F version can also be implemented, but the code will be longer. Considering from the perspective of generality, I still think the 7F version is truly universal.

————————————————————————————————————
　　After re-testing, it is proved that the statement in the above blue content that the 10F code cannot handle spaces is seriously inaccurate. It seems that the 10F version is truly universal.

　　Attached is my test code (intention: get the second-level folder name in the path; result: cannot correctly get the folder name of the specified level):

@echo off

    set file=c:\ab c\def\gh .exe

    set file=%file:\=" "%

    call :Get "%file%"

pause

goto :eof



:Get

    for /f "tokens=2" %%i in (%*) do echo %%~i

goto :eof

Hehe, it has been tested. It can indeed handle paths with spaces, but it cannot correctly obtain the folder name of the specified level in the space path.

NO What Is Cann't...(Chinese English)

@echo off

    set file=c:\ab c\def\gh .exe

    set file=%file:\=" "%

    call :Get 4 "%file%"

pause

goto :eof



:Get

    for /l %%i in (1,1,%1) do shift

    echo %~1

goto :eof
