What’s a Home windows bid formation message(s) I tin usage to acquire the actual datetime successful a format that I tin option into a filename?
I privation to person a .bat record that zips ahead a listing into an archive with the actual day and clip arsenic portion of the sanction, for illustration, Code_2008-10-14_2257.zip. Is location immoderate casual manner I tin bash this, autarkic of the location settings of the device?
I don’t truly head astir the day format, ideally it’d beryllium yyyy-mm-dd, however thing elemental is good.
Truthful cold I’ve acquired this, which connected my device offers maine Tue_10_14_2008_230050_91:
rem Acquire the datetime successful a format that tin spell successful a filename. fit _my_datetime=%day%_%clip% fit _my_datetime=%_my_datetime: =_% fit _my_datetime=%_my_datetime::=% fit _my_datetime=%_my_datetime:/=_% fit _my_datetime=%_my_datetime:.=_% rem Present usage the timestamp by successful a fresh ZIP record sanction. "d:\Programme Information\7-Zip\7z.exe" a -r Code_%_my_datetime%.zip Codification
I tin unrecorded with this, however it appears a spot clunky. Ideally it’d beryllium briefer and person the format talked about earlier.
I’m utilizing Home windows Server 2003 and Home windows XP Nonrecreational. I don’t privation to instal further utilities to accomplish this (though I realise location are any that volition bash good day formatting).
Seat Home windows Batch Record (.bat) to acquire actual day successful MMDDYYYY format:
@echo disconnected For /f "tokens=2-four delims=/ " %%a successful ('day /t') bash (fit mydate=%%c-%%a-%%b) For /f "tokens=1-2 delims=/:" %%a successful ('clip /t') bash (fit mytime=%%a%%b) echo %mydate%_%mytime%
