Current date stamp in batch file?

[Harry Potter]

I want to create a batch file in WinNT to automatically back up a program folder to a progam back-up folder quickly and easily for the purpose of having a copy to which to revert after experimentation or significant code change. In order to do this, I need to both extract the system date and report it in YYYY-MM-DD format into an archive target name. How do I do these?

[foxidrive]

:: timestamp YYYY-MM-DD

@echo off
for /f "delims=" %%a in ('wmic OS Get localdatetime ^| find "."') do set dt=%%a
set date_format=%dt:~0,4%-%dt:~4,2%-%dt:~6,2%
echo %date_format%
pause

Did you really mean Win NT or something later, like XP Pro and after?

I don't fully get the idea, so I'll copy and use the given batch file and study it later. Thank you.

BTW, When I said WinNT, I actually had WinXP and WinVista in mind.

The code will work on XP Pro and higher as they all have WMIC.EXE

For XP Home you'll need different code.

That's a lot of code! Maybe I'll just create a temp. file using echo (i.e. echo Hello, world!>%temp%\t.txt), use for with the same file to set a variable to the date of the file, then delete the file. This leaves one problem, though: how do I format the date?

[foxidrive]

There are simpler ways to do it, if you can limit it to the one machine where regional date settings
aren't ever changed.

Knowing the output of echo %date% would help.

I don't understand. I need the file to run, although with edits, on multiple computers, mostly on WinXP and WinVista. The date format is for easy sorting by name. I might want to program on Win98, but I *know* it can't do any of this at all. :(

If by regional you mean locale and country, then I am in the U.S. and only need to stay in the U.S, as do my software.

[Harry Potter]

If you mean the contents of the %date% variable, I just opened an instance of the command prompt and typed set, and I didn't find the variable.

[Harry Potter]

I did a little experimentation. I created a batch file that accepted a file parameter and returned the file's date/time stamp and tried it out. If I could do that with the test file as stated above and parsed it as stated by foxidrive, I could do it! I believe all the computers I'm using return the same date style. Thank you for your input. I wouldn't have thought of this without your help.

[foxidrive]

Try this.

for /f "tokens= 1-4 delims=/- " %%a in ("%date%") do echo "%%a" "%%b" "%%c" "%%d"

%date% is a system variable and isn't listed in SET. Same as %random% etc.

Try: echo %date%


You're in the US but the regional settings can be changed to add the day name or remove it - you can't be
sure. That's why the more involved script is better: Run this and see...

The top 6 lines show you the result.

Does this batch file also work under WinVista?

The one by Ritchie Laurence does. Not sure which one you meant.

Google groups has a quote option - try and trim unneeded bits when you use it.
It also double spaces - use a Usenet client if you plan to visit regularly, and help others too.

Thunderbird handles Usenet as well as email and is free.

>a little simpler:
echo %date% gives my system date = Mon 05/06/2013
SET DOW=%date:~-14,3% then echo %dow% gives: Mon
SET dd=%date:~-10% then echo %dd% gives: 05/06/2013




SET DOW=%date:~-14,3%

foxidrive: I think I can implement your batch file separately to return the date in YYYY-MM-DD format and return it in a variable. Another batch file (i.e. my backup prg. batch file) can call it and use the results. All the batch files could be in the same folder and this batch file can be located on the path. I will work on this at my earliest convenience. Thank you.

[Harry Potter]

Zaidy026: Does your method *always* read the date in the given format? If it does, I can replace the batch file for program backup in a different thread.

The variations are to extract part of any variable so what you get
depends on your system default for date.
