Questions[batch](server)

I want to have an environment variable that contains the day of week in cmd.exe.

When I run this command I get the result I want.

C:\Users\tisc> powershell (get-date).dayofweek
Friday

Here I'm trying to store the result in an environment variable.

C:\Users\tisc> set dow = powershell (get-date).dayofweek

But when I try to get it I don't get the string as I wanted.

C:\Users\tisc> set dow
DoW=0
dow = powershell (get-date).dayofweek

My goal is to use the variable in a batch file for some backup scripts.

I use %0 in batch file to get the containing directory of the batch file but the result is :-

c:\folder1\folder2\batch.bat

I want just directory, without batch file name, like this :-

c:\folder1\folder2\

How can I do it? Maybe I should filter the path. If yes, how can I do it?

The %DATE% and %TIME% environment variables provide the current date and time on Windows machines on the command line and inside a batch file.

Sadly, those values are locale-aware! Meaning that, say, on a German machine, you will get

26.1.2011

instead of

2011-26-01

this screws up sorting if you want to use this variable in a file name.

Is there any easy way to get hold of a locale-unaware YYYY-MM-DD date string in a Windows batch file?

For the moment, I am working with this rather kludgy workaround:

for /f "tokens=1,2,3,4 delims=. " %%i in ('date /t') do set date=%%k-%%j-%%i
echo %date%

but this is now German locale specific - obviously, a completely independent solution would be much nicer.

The OS in question is Server 2008. I would much prefer not using a third party tool, if at all possible.

I came across a bug in my DOS script that uses date and time data for file naming. The problem was I ended up with a gap because the time variable didn't automatically provide leading zero for hour < 10. So running> echo %time% gives back: ' 9:29:17.88'.

Does anyone know of a way to conditionally pad leading zeros to fix this?

More info: My filename set command is:

set logfile=C:\Temp\robolog_%date:~-4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log

which ends up being: C:\Temp\robolog_20100602_ 93208.log (for 9:23 in the morning).

This question is related to this one.

Thanks

How do I extract multiple archives in contained in subdirectories in a folder, outputting the results back into the folders where the archives are.
