How to go back to first command prompt and close it in bat file

Question

I have a bat file in which I call a couple of bat command sequentially:

start cmd /c a.bat

call b.bat

The 1st line will run a.bat in a new prompt window, after the 2nd line finish run, I want to go back to the window started from 1st line and close it, how can I achieve that? I need to start a.bat in a different window, since b.bat rely on it to run, I have tried

call a.bat

call b.bat

but it never starts b.bat since a.bat starts a server and just wait. Any advice would be appreciated.

Answer 1

Use this and inside a.bat start the server with start "" "c:\\program files\\folder\\server.exe" so it will launch and return control to the a.bat and continue.

call a.bat
call b.bat
