add a counter to the batch file

[Ammammata]

Hi

I use this short batch file:

for /d /r %%d in (*.*) do rd "%%d"

to remove empty folders on a backup device (NAS)

it takes quite a long time to complete, alse because I repeat the
command 10 times, to delete nested folders that have been ignored (not
empty) in the previous run

to avoid the output I add

> nul

at the end, so on screen it shows only the a.m. errors

"The directory is not empty"

now, while it is running

I'd like to see a sort of counter before the error message, to have a
visual confirmation that the command is running :'), i.e.

125 The directory is not empty
288 The directory is not empty
327 The directory is not empty
458 The directory is not empty
and so on

(note skipped numbers, the missing were those successfully deleted)

Thank you

Ammammata,

The below is a basic example of how to implement a counter. I'm sure that
with a bit of work you will be able to incoorporate it into your own batch.
:-)

- - - - - - - - - - - - - - - - - -
setlocal ENABLEDELAYEDEXPANSION
set COUNT=0

for %%v in (a b c d) do (
set /A COUNT=!COUNT! + 1
echo Count = !COUNT!
)
- - - - - - - - - - - - - - - - - -

By the way : not my work, I just found it on the web somewhere and have kept
it for future usage.

Regards,
Rudy Wieser

@echo off
certutil -f -decode %~f0 cr.txt>nul
echo.

for /d /r %%d in (*.*) do (
type cr.txt
echo.|set /p =%%d .
rd "%%d")

del cr.txt
echo.
echo.
goto :eof

-----BEGIN CERTIFICATE-----
DQ==
-----END CERTIFICATE-----

That's a groovy "certificate"!

Bah, and indeed Humbug.

try this - may be faster

SET _SRC=<path>

:: Remove empty folders
FOR /f "delims=" %%i in ('DIR %_SRC% /AD /S /B ^| SORT /R') DO RD "%%i"
> NUL 2>&1

Considering that the CERTUTIL tool is only included starting from in Windows
Vista, using VBScript would be more reliable for at least Windows 2000. e.g.

@echo off
setlocal
>cr.vbs echo wscript.echo vbcr
>cr.txt cscript //nologo cr.vbs
del cr.vbs
set /p a=abc<nul
type cr.txt
echo xyz
del cr.txt

The CR character can also stored into a variable, but DelayedExpansion must
be used to display the CR character. e.g.

@echo off
setlocal
>cr.vbs echo wscript.echo vbcr
for /f %%A in ('cscript //nologo cr.vbs') do set "cr=%%A"
del cr.vbs
setlocal enabledelayedexpansion
echo abc!cr!xyz
endlocal

I haven't checked, but it may also work for other control characters except
NULL (0x00) and ETX (0x03 / CTRL+C) characters.

Heck if you want retro support (and who doesn't run DOS) use a debug
script to create the CR.
off the top of my head, not tested:

mkcr.dbg
<-------------------->
n cr.txt
e100 0D
rcx 1
w
q
<-------------------->

debug<mkcr.dbg
