Batch file logging question

[dpisarek]

I am using the following to del an old log file that a batch file creates:

if exist directory\log del directory\log

What I would like to know is how to create a new log each time the batch file is ran with the date and time included in the file name. So I have a running count of each time the batch file was ran and when it was ran.

Any help would be appreciated.

Thanks all.

How to make a unique string out if %date% and %time% is described here:

The created string can be used as as target file name:

Code: [Select]

for /f "tokens=2-8 delims=/:. " %%A in ("%date%:%time: =0%") do set UNIQUE=%%C%%A%%B%%D%%E%%F%%G
ren stop.log  stop_%UNIQUE%
