Solved Comparing Two File Dates In CMD

  • 2

Hello all

hope you can help.

Using a batch file, I have recently been asked to compare two file dates in a particular folder. Lets say the files names are F1.txt and mail.log.

If mail.log date is prior to F1.txt date then I want the batch file command to run another bat file, wait 20 seconds and then compare two other files within another folder…

____________________________________
The logics is like this:

IF mail.log date < F1.txt date in C:\TEST1 then run Run.bat ELSE
Wait 20 seconds
IF mail.log date < F2.txt date in C:\TEST2 then run Run.bat ELSE
Wait 20 seconds….
____________________________________

There are about 10 of these folders.
-I also do not want to run the Run.bat if the file dates in that folder are the -same, only if the mail.log file less than the F. files
-I also want to remove the time portion of the date

I have looked at some code like this:

SET FILE1=mail.log
SET FILE2=F1.txt
FOR /F %%i IN (‘DIR /B /O:D %FILE1% %FILE2%’) DO SET NEWEST=%%i
ECHO %NEWEST%

but I cannot fit what I have together
Please can someone help

Thankyou

      Wow, I just tested it and there were several problems. That’s what I get for trying to write it in my head.

      Try this:

      @echo off & setlocal enabledelayedexpansion
set #=0
set $=mail.log
set _=F
:_loop
set /a #+=1
pushd c:\TEST%#%
for /f "tokens=*" %%i in (
'2^>nul dir /b/od !$! !_!%#%.txt'
) do (
if {%%i}=={mail.log} (
call run.bat
popd
goto :_loop
) else (
timeout /t 20 /nobreak
popd
goto :_loop
)
)

      Run it from the root of the C: drive.
