How to add an expiry date and time on a windows bat code

P Joshi 21

I need to add expiry date and time with this shutdown .bat code. Any help would be appreciated,

shutdown.exe /r /t 00

All i need is have a date & time with this code so that the code is valid only until its expiration date and time. For example the code becomes invalid after 5th October 2022 at 13:00 pm (1pm).

Thanks in advance

Answer 1

You can add conditions to your batch file. For example see the below sample.

@echo off  
echo "starting the program"  
set expiry=20221002  
set mydate=%date:~10,4%%date:~4,2%%date:~7,2%  
if %mydate% LEQ %expiry% (echo "execute the script") Else (echo "Date Expired")

Basically it sets an expiry date to a number with yyyymmdd format. then from the current date, set another variable with yyyymmdd format. Then do a simble Less than or Equal comparison and if yes execute the script.

You may need to see your date format by entering the dos command Date /T in the command prompt and adjust the statement to extract the date from the current date.

If you have may statements to execute in if statements, try to use goto. Refer: https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/goto

Find the sample output for the script where I set the expriy as Second October

see the execution of else part when I set date as 1st October

Hope this helps

Thank you for your help - its close to what i am looking to achieve. I am not very knowledgable about the codes.

If i want to insert this taskill code to the above code, how can i do it?

TASKKILL /F /IM terminal64.exe

The above code has the date and i ran in cmd prompt and worked as shown above. How do i include TIME as well to the above code.

I did a sample command as echo, instead you can add any command. see the following example.

or you can use go to statements, if you have many statements and need to have well structured file that is easy to maintain. refer the following

I have put the date as 1st of October but it is still executing the code, it should be giving date expired. Am i doing something wrong?
The date displayed in cmd is this: Sub 02/10/2022. If i put date format as 01102022 it gives date expired, and if i put 03102022, it still gives date expired
Sorry for many questions

In Command Line, try the command Date /T, see the output. In my system the output is Sun 10/02/2022, thats why I am doing
set mydate=%date:~10,4%%date:~4,2%%date:~7,2%

%date:~10,4% - will give 2022, starting from 10th index, take 4.
%date:~4,2% - will give 10 - starting from 4th index, take 2
%date:~7,2% - will give 07 - starting from 7th index, take 2

Now if your date format is different, you need to adjust this. One way to see whether you are getting the correct date, do an echo

echo %mydate%

Once you see the response, adjust the indexes to make sure you are formatting the date correct to get yyyymmdd

Looks like my system date is shown as yyyyddmm, now it works correctly. Thank you. I also need to compare time value just like the date. If i have need an expiry date and time as 3 Oct 2022 at 14:00 pm then how can i achieve it? Thanks

%time% will give you the time, and now you can easily create your mydate parameter by adding hour and minute and use that for comparison.

Hope this helps.

Also dont forget to make the post as an answer. :)

thanks, below i added the hour and minute to the date but for some reason its reading it as true while it should be false
expiry is 01 Oct 2022 2100 and system date time is 02 Oct 2022 2106 - it should be giving date expired but isnt

Try a smal trick, add double quotes around both expiry and mydatetime variable, and try
