How to add recursive directory to batch file - batch-file

Question

I have the following batch file:
#echo off
for /f "delims=" %%F in (
'dir /b /a-d [*]*'
) do for /f "tokens=1* delims=]" %%A in (
"%%F"
) do for /f "tokens=*" %%C in ("%%B") do ren "%%F" "%%C"
I want launch it in the root directory and have it go through all directories and subdirectories performing the actions.
I tried adding /D and /r to the 'for' lines, but it doesn't appear to be working.
Do I need add something like...
for /D /r do
under the #echo off ?

Answer 1

Use either dir or for to get all the files, don't mix it up.
When using dir /S for recursive enumeration, regard that full paths are output rather than pure file names only.
This should do it:
#echo off
for /f "delims=" %%F in (
'dir /s /b /a-d [*]*'
) do for /f "tokens=2* delims=]" %%B in (
"%%~nxF"
) do for /f "tokens=*" %%C in ("%%B") do ren "%%~F" "%%C"
So I just changed the following in your original code:
added /s to dir (returns full paths then);
improved second for options (you never used the first token %%A, so why extract it then?);
replaced set %%F of second for by %%~nxF to just parse the file name (type for /? for details concerning substitution modifiers such as ~n, ~x);
replaced source argument "%%F" of ren command by "%%~F" to not fall into double-double-quote problems (the ~ modifier removes potential double-quotes);

Answer 2

You are using "dir" for the enumeration of files, so add "/s" to the DIR command.
I might refactor what you have like this to make it easier to manage.
This also does recursion.
call :TOP .
goto :EOF
:TOP
setlocal
cd "%~f1"
for /f "delims=" %%F in ('dir /b /a-d [*]*') do call :SubRoutine "%%F"
for /D %%x in (*) do call :TOP "%%x" || (echo FAILED2 "%%x" && exit /b 2)
goto :EOF
:SubRoutine
for /f "tokens=1* delims=]" %%A in ("%~1") do call :SubRoutine2 "%~1" "%%A" "%%B"
goto :EOF
:SubRoutine2
for /f "tokens=*" %%C in ("%~3") do ren "%~1" "%%C"
goto :EOF
