how to get next saturday 'Date' in DOS batch file

I have a dos batch file which processes a text file and generates a .csv output file. I want to append the next Saturday date to the output file name.
Right now I am able to append the current date by using the below mentioned logic


Code:

set Pdate=%date:~10,4%%date:~4,2%%date:~7,2% {setting current date to variable}
-outputFile %OUTDIR%\AglItemMaster_"%PDATE%".csv


now I want to pass next saturday date in place of current date.
Kindly help.
A quick response will be really helpful.

I am (or was) Dias de verano.

Output should be next Saturday's date in your local date format. Mine is European dd/mm/yyyy.

Code: [Select]

@echo off
>NextSat.vbs echo wscript.echo FormatDateTime(Date + (7 - Weekday(Date)))
For /f "delims=" %%D in ('cscript //nologo NextSat.vbs') do set nextsaturday=%%D
del NextSat.vbs
echo Next Saturday Is %Nextsaturday%


Code: [Select]

Next Saturday Is 31/07/2010

Thanks a ton Salmon for resolving my issue.
Just a quick one 'how do I convert the output date format from dd/mm/yyyy to yyyymmdd'

Thanks in advance

convert the output date format from dd/mm/yyyy to yyyymmdd'

assuming %NextSaturday% is dd/mm/yyyy

Code: [Select]

set yyyy=%NextSaturday:~6,4%
set mm=%NextSaturday:~3,2%
set dd=%NextSaturday:~0,2%
set yourformat=%yyyy%%mm%%dd%
echo %yourformat%


Hi Salmon,

Code: [Select]

set yyyy=%NextSaturday:~6,4%
set mm=%NextSaturday:~3,2%
set dd=%NextSaturday:~0,2%
set yourformat=%yyyy%%mm%%dd%
echo yourformat %yourformat%
this is not working.

Did you read this?

assuming %NextSaturday% is dd/mm/yyyy

I tested it before posting. It works fine here.

Hi Salmon,
I am using your code in the below mentioned manner

Code: [Select]

@echo off
>NextSat.vbs echo wscript.echo FormatDateTime(Date + (7 - Weekday(Date)))
For /f "delims=" %%D in ('cscript //nologo NextSat.vbs') do set nextsaturday=%%D
del NextSat.vbs

set yyyy=%NextSaturday:~10,4%
set mm=%NextSaturday:~4,2%
set dd=%NextSaturday:~7,2%
set yourformat=%yyyy%%mm%%dd%

echo Next Saturday Is %Nextsaturday%
echo yourformat %yourformat%


And getting the output as

Code: [Select]

Next Saturday Is 7/31/2010
yourformat /210
Please help.
Thanks in advance

you wrongly gave your date format as dd/mm/yyyy when it appears to actually be m/d/yyyy, which is why the code I supplied does not give the result you require.

ohhhhhhh yes I overlooked the date format.
do you know a workaround for converting 'm/d/yyyy' to 'yyyymmdd'

Thanks in advance.

This will place into a batch variable the following Saturday's date in yyyymmdd format. That is, 4 figures for the year and 2 figures each for month and day, (example 20100731) whatever the local date format.

Code: [Select]

@echo off
>NextSat.vbs echo NextSaturday=FormatDateTime(Date+(7-Weekday(Date)))
>>NextSat.vbs echo SY=Year(NextSaturday)
>>NextSat.vbs echo SM=Month(NextSaturday)
>>NextSat.vbs echo SD=Day(NextSaturday)
>>NextSat.vbs echo wscript.echo SY ^& "," ^& SM ^& "," ^& SD
For /f "tokens=1-3 delims=," %%A in ('cscript //nologo NextSat.vbs') do (
Set yyyy=%%A
Set mm=%%B
Set dd=%%C
)
del Nextsat.vbs
If %mm% lss 10 Set mm=0%mm%
If %dd% lss 10 Set dd=0%dd%
Set Result=%yyyy%%mm%%dd%
echo Next Saturday is %Result%
pause


Code: [Select]

Next Saturday is 20100731

The previous code had a possible problem, namely that if today is Saturday, it gives today's date. If you do not want that to happen, the following avoids that, and can be adjusted for any day of the week.

Code: [Select]

@echo off
setlocal enabledelayedexpansion
>evaluate.vbs echo Wscript.echo eval(WScript.Arguments(0))
set VBcmd=cscript //nologo evaluate.vbs
set NDW=Saturday
For /L %%A in (1,1,7) do for /f "delims=" %%N in ('%VBcmd% "weekdayname(weekday(date+%%A))"') do if "%%N"=="%NDW%" set Offset=%%A
for /f "delims=" %%Y in (' %VBcmd% "year(date+%Offset%)" ') do set yyyy=%%Y
for /f "delims=" %%M in (' %VBcmd% "month(date+%Offset%)" ') do set mm=%%M
for /f "delims=" %%D in (' %VBcmd% "day(date+%Offset%)" ') do set dd=%%D
if %mm% LSS 10 set mm=0%mm%
if %dd% LSS 10 set dd=0%dd%
del evaluate.vbs
echo Next %NDW% is %yyyy%%mm%%dd%
pause

Thanks a lot  Salmon!!!
You ROCK!!!!!!
Issue resolved.

Code: [Select]

For /f "delims=" %%D in ('cscript //nologo NextSat.vbs') do set nextsaturday=%%D
echo Next Saturday Is %Nextsaturday%

set yyyy=%NextSaturday:~5,4%
set mm=%NextSaturday:~2,2%
set dd=%NextSaturday:~0,1%
set yourformat=%yyyy%/%mm%/%dd%
echo %yourformat%

Hey I got correction.

Thanks and regards

Hey Salmon.
You are getting help from VBscript or windows script.

Is it fair?
