Using Date and Times in a batch file to create a file name
The Date and Time format depends on what you've specified in the Region and Language Control Panel applet.
Run the following batch file (which assumes dd/mm/yyyy and hh:mm:ss) and modify the substring extraction (using the : and ~ characters) as required to get the proper parts from both Date and Time strings:
@echo off
cls
echo Date format = %date%
echo dd = %date:~0,2%
echo mm = %date:~3,2%
echo yyyy = %date:~6,4%
echo.
echo Time format = %time%
echo hh = %time:~0,2%
echo mm = %time:~3,2%
echo ss = %time:~6,2%
echo.
echo Timestamp = %date:~6,4%-%date:~3,2%-%date:~0,2%-%time:~0,2%-%time:~3,2%-%time:~6,2%
For more help on substring extraction, type set /?
at the command prompt or see this page.
Here's what worked for me.
Format - mmddyyyy_HHMMSS
echo %DATE% %TIME%
Date format = Thu 03/05/2015 15:48:26.22
echo mm = %date:~4,2%
echo dd = %date:~7,2%
echo yyyy = %date:~10,4%
echo Timestamp = %date:~4,2%%date:~7,2%%date:~10,4%_%time:~0,2%%time:~3,2%%time:~6,2%
Timestamp - 03052015_154013
With a little tweaking I got this
@echo off
cls
echo Date format = %date%
echo dd = %date:~0,2%
echo mm = %date:~3,2%
echo yyyy = %date:~6,8%
echo.
echo Time format = %time%
echo hh = %time:~0,2%
echo mm = %time:~3,2%
echo ss = %time:~6,2%
echo.
echo Timestamp = %date:~0,2%_%date:~3,2%_%date:~6,8%-%time:~0,2%_%time:~3,2%_%time:~6,2%
ECHO "TEST..." > test-%date:~0,2%_%date:~3,2%_%date:~6,8%-%time:~0,2%_%time:~3,2%_%time:~6,2%.txt
Result:
"test-do_25_06-2015-22_21_51.txt" (Thursday_25th_June_2015-22:21.51)
