Batch-Loop that opens fixed length filenames in subdirectories

问题

I got this far into making a code (with you guys help on here) but it doesn't do what it's supposed to do..

The goal of the batch is to open all K_E*.dwg files and execute a script on those. The length of the K_E*.dwg files should be 9. Example K_E123456.dwg.

So far, this code opens a dos-window and closes it again.. my folders structure is like this :

C:\Users\b00m49\Desktop\LSPTEST\0031\00\K_E000031.dwg

C:\Users\b00m49\Desktop\LSPTEST\0031\01\K_E010031.dwg

C:\Users\b00m49\Desktop\LSPTEST\0032\00\K_E000032.dwg

C:\Users\b00m49\Desktop\LSPTEST\0033\00\K_E000033.dwg ...

any help into running this code would be great..

I am very new to batch, so explanation about steps may be handy and might allow me to solve small problems.

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET "sourcedir=C:\Users\b00m49\Desktop\LSPTEST"
for /r "%sourcedir%" %%a in (K_E*.dwg) do (
 FOR /f "tokens=1,9delims=\" %%m IN ("%%a") DO (
  REM %%n contain dirname or filename or empty
  REM %%n is only empty for 0, 1 or 2 levels down.
  IF "%%n"=="" (
   SET "name=%%~na"
   IF "!name:~9!"=="" IF "!name:~8!" neq "" (
    REM the name is not longer than 9 characters, but IS longer than 8
     ECHO(start /wait "C:\Program Files\Autodesk\Autocad 2013\acad.exe" "%%a" /b "C:\Users\b00m49\Desktop\LSPTEST\expSQM.scr")
   )
  )
 )
)
GOTO :EOF

You may use this method instead, that offer a better identification of the desired file names:

@echo off
setlocal

set "sourcedir=C:\Users\b00m49\Desktop\LSPTEST"
cd "%sourcedir%"
for /F "delims=" %%a in ('dir /S /B K_E*.dwg ^| findstr "\\K_E[0-9][0-9][0-9][0-9][0-9][0-9]\.dwg"') do (
   ECHO start /wait "" "C:\Program Files\Autodesk\Autocad 2013\acad.exe" "%%a" /b "C:\Users\b00m49\Desktop\LSPTEST\expSQM.scr"
)

The for /r "%sourcedir%" %%a command is replaced by a cd "%sourcedir%" and a posterior dir /S command; this method process the same files: all files at any level inside the source dir. The list of files is passed via a | pipe into findstr filter command, that allows to pass just those names that have "\K_E"+6 digits+".dwg" precisely. For further details, type findstr /?. The output is taken by the for /F "delims=" %%a command.

PS - Why you use start /wait command? its net effect is the same as execute the acad.exe command alone...

I'm new to this website, and didn't notice that someone edited his comment into something that works..

I don't completely understand how, but here's the code.

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET "sourcedir=U:\Users\b00m49\Desktop\LSPTEST"
for /r "%sourcedir%" %%a in (K_E*.dwg) do (
 FOR /f "tokens=1,9delims=\" %%m IN ("%%a") DO (
  REM %%n contain dirname or filename or empty
  REM %%n is only empty for 0, 1 or 2 levels down.
  IF "%%n"=="" (
   SET "name=%%~na"
   IF "!name:~9!"=="" IF "!name:~8!" neq "" (
    REM the name is not longer than 9 characters, but IS longer than 8
     ECHO(start /wait "" "C:\Program Files\Autodesk\Autocad 2013\acad.exe" "%%a" /b "C:\Users\b00m49\Desktop\LSPTEST\expSQM.scr")
   )
  )
 )
)
pause
GOTO :EOF

Change

 ECHO(start /wait "C:\Program Files\Autodesk\Autocad 2013\acad.exe" "%%a" /b "C:\Users\b00m49\Desktop\LSPTEST\expSQM.scr")

 start /wait "" "C:\Program Files\Autodesk\Autocad 2013\acad.exe" "%%a" /b "C:\Users\b00m49\Desktop\LSPTEST\expSQM.scr")

or to

 start "" "C:\Program Files\Autodesk\Autocad 2013\acad.exe" "%%a" /b "C:\Users\b00m49\Desktop\LSPTEST\expSQM.scr")

which should run all of the conversions in parallel.
