DOS: create filename based on date?

Issue

I need to be able to automatically generate a DOS .txt filename that is the 'date' of when it is created.

Any ideas? My DOS is rather rusty and have run out of ideas.

Solution

You might try something like this:

set filea=MyBigFile%date:~10%%date:~4,2%%date:~7,2%%time:~0,2%%t ime:~3,2%.sav 
copy MyData.dat %filea% 

Since the date is Thu 07/30/2009 and the time is 14:07:00.00,
For today this would give a file named
MyBigFile200907301407.sav
