Batch script - Run exe program one after another

Question

I have some EXE programs,Want to run using batch file one after another.

Actually one set contains 2 EXE programs with some parameters.

Example.

@echo off  
start prog1.exe
start prog2.exe

/---wait untill prog1.exe and prog2.exe finish--/

start prog3.exe
start prog4.exe

Answer 1

To run the .exes sequentually you need to pass the /wait parameter to start

e.g.

@echo off  
start /wait prog1.exe
start /wait prog2.exe
start /wait prog3.exe
start /wait prog4.exe

However that does not run start1 and 2 in parallel. For more complex use see answers to this question
