Did it work for you?

Assign value from %%j to a variable

Project: to manipulate files in a single folder depending on each file's creation date (compare with a
cutoff date).
I've approached this with dir with suitable switches writing to a temporary file. Then parsing the file
with "for /f"; the filedate and filename appearing in variables %%j and %%k.
The command I'm trying to use is:

for /f "skip=5 tokens=1,4" %%j in (%Temp%\DirListing.txt) do (
   if "%%k"=="bytes" goto :finished
   echo #%%j#   #%%k#
   :: rather more coding here
   )
:finished

My problem then arises trying to compare %%j with the cutoff date. [I can format that as necessary].
"set FileDate=%%j" does not operate as I hoped.
How do I get %%j into a variabe that I can use for further coding. The same problem will apply to FileName from %%k.

Or is there a better approach to this problem?

Ray

PS. If it was for myself I would use Xxcopy but in this case additional software is prohibited.

You can use the file date and time stamps in %%~ta with delayed expansion

 <at> echo off
setlocal enabledelayedexpansion
set cutoff=20111206
for /f "delims=" %%a in ('dir /b /a-d') do (

See you in alt.msdos.batch.nt

Hi Guys 'n Gals.

I'm leaving this group because the moderator has left, and left it as a closed group.

If anyone needs help for batch files then do feel free to visit the newsgroup

alt.msdos.batch.nt

either with a Usenet program or via Google Groups.

All Windows OS are discussed from NT and more recent - and people there are even familiar with Win9x and MSDOS.

Cheerio,

It takes a different way of getting the file date which is dependent on regional and country settings.  
The /t:c gives the creation date and then DIR information is parsed for it.

Read the comments below and try it out - it expects the filenames to have a . in the filename.ext and your
filespec can replace *.bat below.

 <at> echo off
setlocal enabledelayedexpansion
:: This code reports when files are older than a cutoff date
:: using the creation date.  DIR date format is assumed to be 
:: DD/MM/YYYY and remove the REM parts below for MM/DD/YYYY

:: cutoff date is in YYYYMMDD format.
:: Other commands can be added to process these files.

set cutoff=20091210

for /f "tokens=1,2,3,* delims= " %%a in (
'dir *.bat /t:c /a-d ^|find "."'

This doesn't require the filenames to have a period or a filespec.

It's significantly different now as searching the subdirectories when parsing a DIR list requires a lot of
fiddling, and the DIR format from the OS has to be right too.

So this is tested under XP Pro SP3 and the DIR spacing may not be the same in Win7 etc (with the filenames
starting in column 37).

Filenames containing ! and % will probably fail.

 <at> echo off
setlocal enabledelayedexpansion
:: This code reports when files are older than a cutoff date
