This question for windows batch file where I am trying to run multiple batch file from master file

I have a special requirement where i am trying to run child bat files from a master bat file. But there are multiple issues that i am running into.
1. Master does not wait for child to get completed and completes without waiting for child file completion. Which means i can not schedule it as job.
2. When i am doing parallel execution inside master file, it does not go to the next line of execution.
I am posting a high level scenario, please let me know the correct way of doing it.

parent A (don't finish till all child and grandchild are done)
----------->parallel child 1
---------------------->grandchild a
---------------------->grandchild b
--------------------------------->parallel great grandchild b1
--------------------------------->parallel great grandchild b2
---------------------->grandchild c (don't start this till both great grandchild b1 and great grandchild b2 are done)
---------------------->grandchild d
--------------------------------->parallel great grandchild d1
--------------------------------->parallel great grandchild d2
-----------> parallel child 2
---------------------->grandchild d
---------------------->grandchild e
--------------------------------->parallel great grandchild e1
--------------------------------->parallel great grandchild e2
---------------------->grandchild f (don't start this till both great grandchild e1 and great grandchild e2 are done)
---------------------->grandchild g
--------------------------------->parallel great grandchild g1
--------------------------------->parallel great grandchild g2

Any help would be appreciated.

What I have tried:

I have tried the parallel execution using Start and normal series execution but it does not work for me in this case.

Solution 1

I have no idea how you're launching the other batch files, because you don't show the code, but you can always use START /WAIT batchFile parameters to launch it and wait for it to complete.

Hi Dave,

i am adding a reference code for you.

Code for Master file:-
start "C:\Test\Parallel_batch_process\chlidA.bat"
start "C:\Test\Parallel_batch_process\chlidB.bat"

ChildA:-

start "test1" cmd.exe /C ^(ping server1 -n 2 ^> C:\Test\Parallel_batch_process\Test1.txt^)
start "test2" cmd.exe /C ^(ping server2 -n 2 ^> C:\Test\Parallel_batch_process\Test2.txt^)

ChildB:-
start "test1" cmd.exe /C ^(ping Server3 -n 5 ^> C:\Test\Parallel_batch_process\Test3.txt^)
start "test2" cmd.exe /C ^(ping Server4 -n 2 ^> C:\Test\Parallel_batch_process\Test4.txt^)

There is one more extension to this where i am calling GrandChild from the Child files, but for if this much only works then i can go for the next level.
