Title: Batch file
Post by: vmakhon1 on June 30, 2005, 08:27:45 AM

Hello everyone,
I have a log file on Windows 2000 machine, which collects all logs based on a date. My goal is to create a batch file, which can delete everything besides first 7-8 instances ( or lines). How can I tell the batch file to start deleting beginning with 9th, for example, line or may be after predefined date? Please, help me
Thanks
Vlad

This little piece of doggeral will select the first nine records of the file and dump them in a new one. Batch language calculations are cheesy at best, and dates are out of the question.

Make any changes accordingly. This just illustrates technique:

Code: [Select]


@echo off
set count=0
if exist path\newfilename del path\newfilename
for /f "tokens=1* delims=" %%i in (path\filename) do (
     set text=%%i
     call :Subr %count% %text%
     )
           
     
:Subr      
     if %count% leq 9 (echo %text% >> path\newfilename)
     set /a count=%count%+1


Good luck. 8)
