Various RunCommand procedures in process unit:

But it looks like it hangs around until the started process exits...
How can I set a timeout on the execution (don't want the whole system
to hang if this external program does not exit)?
And if I just want to start a process but not wait for it to exit?
Use TProcess.
https://www.freepascal.org/docs-html/current/fcl/process/tprocess.html
do NOT specify poWaitOnExit in the options, and simply call Execute.
It will return at once.
To clarify:
If I do not specify [poWaitOnExit] to Execute, then it will return
immediately with the process running and I can check whenever I like
if it is still running using the Running() method.
This seems like I can do what I need.
Question:
---------
If I free the TProcess object will that terminate the running process
or just detatch from it?
It detaches.
Michael.
