Question

BATCH to remove empty directories... with logging.

Asked by: noodleNT

Does anyone know RD always returns an errorlevel of 0 with this script? On the screen it will say that the folder couldn't be deleted because it wasn't empty but still output and exit code of 0. Yet when manually type the RD on a directoy that isn't emty in a DOS window I get a negative error code.

for /f "usebackq delims=" %%d in (`"dir /ad/b/s | sort /R"`) do (
 
	rd "%%d"
	IF %ERRORLEVEL% NEQ 0 (
				
		Echo Removing Folder: >> Delete.Log
		Echo "%%d" >> Delete.Log
		ECHO CODE: %ERRORLEVEL% >> Delete.Log
		Echo. >> Delete.Log
		Pause
	)
)

That may give you another approach,

The created tmp$$$.bat file would contain something like
rmdir c:\xchange\quil
rmdir c:\xchange\arch
rmdir c:\xchange
rmdir c:\vpp\mr
rmdir c:\vpp\dat
rmdir c:\vpp


 
@echo off
::
:: Build a list of directories of the target file
:: Pipe through reverse sort to last handle subdirectories
dir c:\*.* /a:d /s /b /l|sort /r> tmp$$$.dir
::
:: Make and call a batch that removes all directories
:: The crucial trick is that MS-DOS will only remove empty ones
type tmp$$$.dir | SED15 -e "s/.*/rmdir &/" > tmp$$$.bat
 
 
:: To actually run it, remove the rem
rem call tmp$$$ >> Delete.Log
 
 
::
:: Show what is left
dir c:\*.* /a:d /s /b
::
:: Clean up
for %%f in (tmp$$$.dir tmp$$$.bat) do if exist %%f del %%f
for %%f in (marker.$$$ c:\temp\marker.$$$) do if exist %%f del %%f

I like the idea of the redirect but how would I get it to only log the folders that were deleted?

I am assuming I would write the error to file and then run another For statement to see what the error is? It could work, but it would be slow. Is there a better way?

ok
try this

@echo off & setlocal
:: *** goto folder
cd /d C:\temp\iii
:: *** set log files
set ERRlog=C:\TEMP\ERRDeletedfolder.Log
set OKlog=C:\TEMP\OKDeletedfolder.Log
:: *** if you don't want log remove the comment "::"
::  set OKlog=NUL
::  set ERRlog=NUL
 
:: *** empty log files
type nul >C:\TEMP\OKDeletedfolder.Log
type nul >C:\TEMP\ERRDeletedfolder.Log
:: *** msg checked The directory is not empty
 
::single line
for /f "usebackq delims=" %%d in (`"dir /ad/b/s | sort /R"`) do 	(rd "%%d" 2>&1 |find   /i "The directory is not empty") && echo ERROR: Not empty %%d >>  %ERRlog% || echo deleted  %%d  >>  %OKlog%
