I'm having an issue getting 2 scripts featured on this site to work. I know I'm missing something simple. The 2 I'm trying to use are the top 2 @ http://www.dostips.com/DtTipsDateTime.php

I want the batch file to figure out the date, then delete anything in that directory thats 180 days or over.

Any help would be appreciated.

natively, you can use vbscript

Code: Select all

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder("C:\temp")
For Each efile in objFolder.Files
 'Wscript.Echo "file is " & efile
 'WScript.Echo eFile.DateLastModified
 If DateDiff("d",eFile.DateLastModified,Now) >= 180 Then
   WScript.Echo "file found that is 180 days old: " & efile
   WScript.Echo eFile.DateLastModified   
   'objFSO.DeleteFile(eFile)   'remove the quote to do actual deletion
 End If 
Next

or if you can, download findutils

Code: Select all

C:\test>find c:\test -mtime +180 -delete

While I'm sure both work well, it's outside the scope of this project. If I can get this part of the batch script to work correctly, it'll be added to a much larger batch file that does cleaning on servers.

Spellman
Try use Forfiles

Code: Select all

/D    date          Selects files with a last modified date greater
                    than or equal to (+), or less than or equal to
                    (-), the specified date using the
                    "dd.MM.yyyy" format; or selects files with a
                    last modified date greater than or equal to (+)
                    the current date plus "dd" days, or less than or
                    equal to (-) the current date minus "dd" days. A
                    valid "dd" number of days can be any number in
                    the range of 0 - 32768.
                    "+" is taken as default sign if not specified.

nevertheless WSH may successfully used from CMD by single or multiple script files, it is more fast & simple than via native CMD calculating

Would like to use forfiles, however it's not on every server. The script will need to run on WinNT, 2000, 2003, 2008. Obviously, have to make it for the weakest link

it is sample of effective combinaition BAT & JS in one CMD-file:

Code: Select all

@set @x=0 /*
@echo off

set DIR=%TEMP%\*
set OLD=3000

for /f "delims=" %%i in (
'dir /b/s/a-d "%DIR%"^|cscript //nologo /e:jscript "%~0" "FileOldDays(%OLD%)"'
) do del /f/q "%%~i"

EXIT

*/
eval(WScript.Arguments.Item(0));

// ===== functions block =======

function FileOldDays(olddays) {
  var str, obj, dof, now, dif
  var fso = WScript.CreateObject("Scripting.FileSystemObject");

  while (!WScript.StdIn.AtEndOfStream) {
    str = WScript.StdIn.ReadLine();
    if (fso.FileExists(str)) {
      obj = fso.GetFile(str);
      dof = Date.parse(obj.DateLastModified);
      now = new Date()
      dif = Math.floor((now-dof)/(1000*60*60*24))
      if (dif>=olddays) WScript.StdOut.WriteLine(str);
    }
  }
}

I do appreciate the help amel27
While I do fully plan on writing this in a few other languages, I'd like to finish the batch version before I move on to a vbscript/jscript.

I've run into a new issue. I figured (I think) what I was doing wrong and got it to work. HOWEVER, when I do controlled test runs on a remote server I get drastic results.
When I ran the batch file, it saw FileA at 70 days old (which is correct). When I ran it on the remote server it found it to be just over 2 millenia old. It saw the file as 730,555 days old. Same script, same file, just ran from different servers. The date is correct on both, though I'm not even sure it's possible to set your calendar off by 2,000 years.

Here's what I'm using for code... Most of it is from this site with one addition by me. (First part "TimeDelete" i added so that I could add it to my script and have it loop threw this with different directories and days.)

Sorry for the wall of text, but unless you have what I'm using it's impossible to be 100% on. And for what it's worth I use Notepad++

:TimeDelete dir days -- Sets the variables below for dymanic uses
:: -- dir [in] - Parent directory to scan
:: -- day [in] - Anything after this in days will be removed
SETLOCAL ENABLEEXTENSIONS

call:ftime tfile "%%F"
set /a diff=tnow-tfile
echo.%%~nxF is !diff! days old
call:DeleteIfOld %%~nxF %2
)
ECHO.&PAUSE&GOTO:EOF

eleteIfOld name days tnow -- deletes file or directory if older than given number of days
:: -- name [in] - name of file or directory
:: -- days [in] - number of days to expire
:: -- tnow [in] - today's date in julia days

SETLOCAL
set "days=%~2"
if %diff% LEQ %days% EXIT /b
set "attr=%~a1"
if /i "%attr:~0,1%"=="d" (
rd /Q /S "%~1"
) ELSE (
del /Q /S /F "%~1"

)

:ftime JD filename attr -- returns the file time in julian days
:: -- JD [out] - valref file time in julian days
:: -- attr [in,opt] - time field to be used, creation/last-access/last-write, see 'dir /?', i.e. /tc, /ta, /tw, default is /tw

SETLOCAL

if not defined attr (call:jdate JD "- %~t2"
