Again with Parallel Process
Posted: 27 Sep 2012 23:52
I found this in Parallel process Code form googlling the start process at the same time in same window... like ping few ip's at the same time form same window...
i have ipadd.csv user.txt pass.txt i have try lot to do that it start psexec.exe in parallel process. but not able to solve.
there is options there but i can't work out i don't wan't ping option just psexec.exe option..
Pls help with this.
Code:-
@echo off
setlocal enableDelayedExpansion

if /i "%~1" equ "/O" (
set "lockHandle=1"

set "showOutput="
)
