How to schedule taskkill in bat file

Question

I want something like this:-

taskkill 7z.exe after 50sec.
code 1
code 2
code 3 

7z.exe will be killed after 50 sec but the program should execute code 1 code 2 code 3 without waiting for the taskkill. May be 7z.exe would be killed when code 2 is being executed.

Answer 1

To kill 7z.exe after 50 seconds, you should use

start 7z.exe
timeout /t 50
taskkill /im 7z.exe

Put this in a batch file and use start to launch this process independently of the other (code1, code2, code3) stuff.

Answer 2

If CPU usage is important, may want to use ping with a loopback address and a timeout, like so:

@echo off
:: Pause for approx. 50 seconds
PING -n 51 127.0.0.1>NUL 2>&1

:: Force kill 7-zip
taskkill /f /im 7z.exe
