Since 'date math keeps coming up, I'll have a go.

It will be helpful if a few of you using NT/XP/vista run the bat below and post the first few lines. [Sorry, no good for Me/9x/DOS]

::=====================
@echo off > #

for /f "tokens=* delims= " %%a in ('dir/b/a-d/o-d') do (
echo %%~TNa
)

date math for files like getting the modification date should be done in vbscript (for example) if you want it to be cross platform or to work in different M$ OS versions.

Hi ghostdog,

Dumb question of the day:

Does VBS work in w9x?

yes

delete files older than 30 days

Dim fso
Dim oFolder
Dim oFile

Set fso = createobject("Scripting.FileSystemObject")
Set oFolder = fso.GetFolder("C:\Temp")
For Each oFile In oFolder.files
If DateDiff("d", oFile.DateCreated,Now) > 30 Then
oFile.Delete True
End If
Next

Set oFolder = Nothing
Set fso = Nothing

the version of the WSH engine in windows 98,2000 and millenium is either 1.0 or 2.0. You can download the latest version (think its 5.6) if you want to use vbs in those platforms. Its good to know about vbscript, since its the next best thing to DOS, natively.

You also got me and ghostdog here, if you need help.

Also, while learning VB*, I suggest you make your first line read Option Explicit.

Here's another output I've got today:

07/Tue/08/29 18:25 #

What sort of format is that? 07 is the month, 08 is the year, 29 is the day. Completely insane, I agree, but possible nevertheless.

How did I do that? Easily. I just went into Control Panel, Regional Settings, Customize... the date format is completely configurable.

Which proves there is an almost infinite number of possible formats for the date, and it is impossible to do it in batch.

Back when I ran Win98, I had my time set up as

Why? because that's how it would be displayed on my task bar.

The difficult we do right away.

The impossible takes a little longer.
