And when the script ends it sends hup to the program and it may end.
The very best way is to for the program to "daemon"ise itself, see
the function man 3 daemon. That way you can just invoke the program.
You can do something like
nohup /root/programs.d/my_program &
to sort of make the program a daemon. But beware, any stdout stuff will
probably be appended to a file called /root/nohup , which can build up and
up and up.
