Maybe I'm misunderstanding your meaning, but usually programs which do
this don't do anything unusual other than... well... simply run forever
in the background (launched from the startup scripts or cron, disassociated
from any TTY, of course).  A watchdog re-launcher cron script is also
not uncommon.

If your script isn't actively doing something it's good to put it to
sleep until some interesting event (or timer) wakes it up.

Was there something beyond that you were looking for?
