Running another program in Windows bat file and not create child process

Question

I have subversion server with a post-commit hook to do something.

I want the checkin finish soon, not wait the hook script. But by design, the Subversion post-commit hook script will run until all child process exit, so using somthing like:

start another_prog...

in the hook bat file has no use.

So I want to know how to run another program in Windows bat file which not create child process or let the child process detach from the parent.

Answer 1

Synchronous. The second notepad won't launch until you close the first.

notepad.exe c:empa.txt
notepad.exe c:emp.txt

Asynchronous: The second notepad will launch even if you haven't closed the first.

start notepad.exe c:empa.txt
start notepad.exe c:emp.txt

EDIT: The following comment was made elsewhere by @zhongshu, the original poster. I'm only copying it here:

start cmd /c doesn't work because SVN post-commit hook will wait for the hook and the child process created by the hook exit. It's the design of SVN. I have found a solution, Please refer: http://svn.haxx.se/users/archive-2008-11/0301.shtml

Assuming that he knows what he's talking about, I'm wrong and...undeserving.
