Yesterdays Date

[dearnr]

Firstly thanks for looking  

I have a batchfile that does a backup to a different server in a folder with yesterdays date + b so tonights will be :
25092005b

then i run a processing batch which works file

Then i do another back up which copies the files after the batch has finished and calls it todays date + a

26092005a

the problem I have is I dont know how to get yesterdays date (today - 1).

My batch file looks like this:



for /f "tokens=1-3 delims=/ " %%a in ('DATE /T') do set zdatea=%%a%%b%%c

Rem lux Back up - before the batch
REM I need something here to take one day away
md x:\backups\lX\%zdatea%c
Xcopy L:\Arev\LfdatlX x:\backups\lX\%zdatea%c


cls
l:
cd \arev
arev LAL /x m4096

for /f "tokens=1-3 delims=/ " %%a in ('DATE /T') do set zdateb=%%a%%b%%c

Rem lux Back up - ater the batch
md x:\backups\lX\%zdateb%A
Xcopy L:\Arev\LfdatlX x:\backups\lX\%zdateb%a

cls

Many thanks for your help

Some hints needed:

What is arev and b & c variables.

[dearnr]

sorry tried to be a bit more descriptive

for /f "tokens=1-3 delims=/ " %%a in ('DATE /T') do set zdatea=%%a%%b%%c

Rem lux Back up - before the batch
REM I need something here to take one day away
REM as the backup happens at 2:00am so if I use
REM date then is actually the next day.

md x:\backups\lX\%zdatea%c

REM above line makes a directory in following format:
REM X:\backups\lx\260905c

Xcopy L:\Arev\LfdatlX x:\backups\lX\%zdatea%c
Rem Above copies files in directory to this back up server

REM ************************************
REM This runs another batch.
REM all this works fine

Calculate for example:

Set /a day=27-1


This should work for you: (I assume %%a is the day)

for /f "tokens=1-3 delims=/ " %%a in ('DATE /T') do (

set /a day=%%a-1
set mj=%%b%%c
set zdatea=%day%%mj%
)

I think i have leanrnt somehting here,

uli those b and c variables come from the partition due to the delims.

Am i right?

[dearnr]

sorry but Im obviously not doing something right.

The variable zdatea seems to be blank so no folder is created.

Any ideas?

[uli_glueck]

mh.
Please tell what exactly date /t gives you on the screen. Then I will do it for you.

I get Fr 28.09.2005

I get 28/09/2005

[dearnr]

sorted now.

I do the following:


Set fso = Wscript.CreateObject("Scripting.FileSystemObject")
dtmYesterday = date() - 1
dtmYesterday = Replace(dtmYesterday, "/", "")
dtmYesterday = Replace(dtmYesterday, "2005", "2005Before_Batch_AUTO")
Set f = fso.CreateFolder ("X:\Backups\Lx\" & dtmYesterday)

dim filesys
set filesys=CreateObject("Scripting.FileSystemObject")
If filesys.FolderExists("L:\Arev\Lfdatlx") Then
  filesys.CopyFolder "L:\Arev\Lfdatlx", "X:\Backups\Lx\" & dtmYesterday
End If

works perfectly so thanks everyone for your help

Hi,

sorry that I am a bit late, we have beer festival in munich at the moment. :-)

This should do the job:

for /f "tokens=* delims=/ " %%a in ('date /t') do set date=%%a

set day=%date:~,2%
set /a lday=%day%-1
set month=%date:~3,2%
set year=%date:~6,4%

echo %lday%%month%%year%

There is only a little bug, if it is the first of a month.
Not every month has the same number of days....
That makes it a bit tricky.
But would be interesting to do in a batch file. Needs a bit time. :-)

greetings
