Hi,
try this, note that to run from a command line you need one % sign in front of the A(as below), if you put this in a batch file you'll need to change it to two - %%A

rem - get todays date
for /F %A in ('date /t') do set today=%A

rem - the output (uk) is dd/mm/yy but you want
rem dd-mm-yy so change the \ to a -
set today=%today:/=-%

rem - now do the rename
ren myfile.fil %today%.fil

Hope this helps.....

It actually only takes 1 line in a BAT file:

for /f "tokens=1-4 delims=/ " %%i in ('date /t') do echo %%j-%%k-%%l

That like will take the DATE command (which displays output like TUE 05/07/2002) and breaks up each piece between the spaces and the front slashes, and assigns each one to a separate variable.
So in the example, %%j = the month (05)
%%k = the day (07)
and %%l = the year (2002)
and %%i = the day in alpha (TUE)
You could then arrange the variables in any order when you rename your file. For example, after you run the FOR /F command, do this:

copy db_base %j%-%k%-%l%

That would make a copy of your file and call it 05-07-2002 when run today; tomorrow, its 05-08-2002

And yes, in the BAT file, use the double % signs for the FOR /F line, but %letter% in the copy line.

hope this helps

Dang it! Forgot, the variables set up on the FOR /F line are only good when you are still ON that line. I always forget that!

Ok, the BAT file is down to 1 line. Try this:

for /f "tokens=1-4 delims=/ " %%i in ('date /t') do copy db_base %%j-%%k-%%l

That will copy the file called db_base and call the copy 05-07-2002

Now, if you need to just rename the existing db_base file and not make a copy of it, just replace the COPY command in the FOR /F line with RENAME. You get the point.

Sorry for the confusion, but this one line is all you need.
