Nice simple one for someone (i hope).... which for some reason I cant figure out or find a simple solution... :)

Ive whipped up a script (on windows 2003) as follows :

dir /S *.mp3 >c:\temp\mp3_%date%.txt

My problem is whenever it runs, the output file is "mp3_Tue" - I require the whole date preferably like 28072009 or similar.

How the fudge do I get it to do this ? All the information Ive found via Google points to running a 20 line script just to create the date variable.... gotta be easier way than that.

Turns out there is no easy way.... so have to add 5-15 lines to my script to get it to work.... wouldve thought it was an easy thing to do for an advanced system like Windows :-p

ok for only an additional line of code try:
dir /S *.mp3 > c:\temp\mp3_temp.txt
ren c:\temp\mp3_temp.txt c:\temp\mp3_%date:~4,2%-%date:~7,2%-%date:~10,4%_@_%time:~0,2%h%time:~3,2%m%time:~6,2%s%.txt

for debugging purposes use:
echo %date:~4,2%-%date:~7,2%-%date:~10,4%_@_%time:~0,2%h%time:~3,2%m%time:~6,2%s%

to play around with the formatting.
