I want to delete all 「name.jpg」 and rename 「name_.jpg」 to 「name.jpg」 in windows.
The file structure is like this.

>upperFolder

  >p1

    >學生_二反田●雄.jpg

    >學生_二反田●雄_.jpg

    >學生_半田●男.jpg

    >學生_半田●男_.jpg

    >學生_潘●.jpg

    >學生_潘●_.jpg

    >...

  >...

  >p7

    >學生_石井節●.jpg

    >學生_石井節●_.jpg

    >學生_王裕●.jpg

    >學生_王裕●_.jpg

    >學生_●垣  勇.jpg

    >學生_●垣  勇_.jpg

delete p1/學生_二反田●雄.jpg

rename p1/學生_二反田●雄_.jpg p1_學生-二反田●雄.jpg

The final result looks as below.
p1_ is to prevent repeat filename and - seperate student name.

>upperFolder

  >p1_學生-二反田●雄.jpg

  >p1_學生-半田●男.jpg

  >p1_學生-潘●.jpg

  >...

  >p7_學生-石井節●.jpg

  >p7_學生-王裕●.jpg

  >p7_學生-●垣  勇.jpg

How can I make this in bat or php?

I have tried

mkdir tmp



for /f "eol=: delims=" %%D in ('dir /b /s /ad *^|sort /r') do (

  pushd "%%D"

  for %%F in (*) do move "%%F" "..%%~nxD_%%F" >nul

  popd

)



move *_.jpg tmp

del *.jpg

cd tmp 

move *.jpg .. 2>NUL

but can't get rid of the last '_'

There are no wildcards in CMD to not match a character, so instead you could temporally change the extension of the files whose names end with _:

Note: remember to run the following snippets from upperFolder and to change the %g for %%g if you're running from a batch file.

:: /r stands for recursive and ~n stands for (file)name

for /r %g in (*_.jpg) do ren %g "%~ng.jphg"

Then you can delete the files whose names do not end with _:

del /s *.jpg

And finally rename and move the files whose names end with _. But you're asking for something tricky and that is to prepend the filename with the directory name containing it, replace the inner _ of the filename with -, remove the trailing _ of the filename, and then move the file to upperFolder:

:: so that the variable expansion inside for's works as expected

setlocal EnableDelayedExpansion

:: loop through all the directories and store the names in g

for /d %g in (*) do (

    for %h in ("%g*_.jphg") do (

        set "newname=%~nh"

        :: remove trailing _

        set "newname=!newname:~0,-1!"

        :: replace ALL _ with -, assuming the filename only has one inner _

        set "newname=!newname:_=-!"

        :: prepend directory name and restore extension

        set "newname=%g_!newname!.jpg"

        :: rename and move to current directory

        move %h ".!newname!"

    )

)

Something like this should work for you:

for %%a in (*.jpg) do del /y "%%~a" & ren "%%~na_%%~nx" "%%~nxa"

Here we:

• search all files of type jpg
  
  
  
  
  • delete those found
  
  
  • and then rename files with same name ending with _ into names of original files
  
  
  
  

See for /? command or this for more information about %%~na and similar.

Please note that unless your system OEM codepage supports kanji this will not work. You can get around this problem by switching to UTF-8 encoding by issuing command CHCP 65001 and saving batch file as UTF-8 (no BOM). See this for more information.
