Question

how to write a "bat" file to implement two "exe" files by turns multiple times

Answer 1

A:

Sounds scary...

You need to keep File Locking in mind so your applications do not step all over each other.

Two processes that modify the same shared resource can lead to all sorts of troubles.

Is this for work/fun or school?

Yes, just for doing TA job.

Answer 2

A:

@Echo Off
SETLOCAL EnableDelayedExpansion
SET LIST=cmd cmd

FOR %%G IN (%LIST%) DO (
SET NAME=%%G
START /WAIT CMD /C !NAME!
)

How to control the times of loop if using start?

I was merely responding to Roberts valid point regarding file locking. When you wrap the execution to the loop, the loop will wait until the first program exits before launching another iteration. See simple edited test.

Thanks you very much. I have figured out my problem using Matlab. Matlab are allowed to embed dos command. So in this way, I can use the "for" loop in Matlab. At last, Thanks again.

Answer 3

A:

You can use for loops in batch files. It's not completely clear what you are wanting, but the following command will run a.exe and then b.exe 3 times each passing the parameter c.dat to each one:

for /l %l in (1,1,3) do for %a in (a.exe b.exe) do %a c.dat

This is really helpful. I have another question. If I have to execute a "exe" file and a java file(.class). How should I write it. I have tried it in this way: "for /l %l in (1,1,3) do a.exe c.dat java b c.dat".But it failed.

@FihopZz, In that situation, it might be simpler to make another batch file (b.bat maybe) that runs the java app.
