Windows CMD run a command and inject the date

Question

I have the following command:

c:\run.exe >> c:\log.txt

I actually want:
c:\run.exe >> c:\log_19-07-2016.txt

Can it be done?

Thanks

I stole from Stack Overflow for you after discovering the old batch assets I had lying around used a different date format and therefore didn't give the right format. Add this to the top of your script:

for /f %%I in ('wmic os get localdatetime ^|find "20"') do set dt=%%I
REM dt format is now YYYYMMDDhhmmss...
set dt=%dt:~4,2%-%dt:~2,2%-%dt:~0,4%

set outfile = "c:\log_%dt%.txt"

Then use:

c:\run.exe >> %outfile%

instead of the other command.
