How to run a program as a service (silent)?

Turn it to a daemon (service)
daemon --name="yourservicename" --output=log.txt sh yourscript.sh

Even old bash is using & for sending processes to background, but there is few other ways too .. but basic two are these :

1.)$~ your_command > outputfile_for_stdout &
        # runs your command in background, giving you only PID so you can exit that process by `kill -9 PID_of_process`
        # & goes at the end of row      


2.)$~ your_command > outputfile_for_stdout 
        # this will run your program normally
        # press  Ctrl + Z then program will pause
   $~ bg
        # now your program is running in background
   $~ fg
        # now your program came back to foreground
3.)you can run terminal window under screen command so it will live until you either kill it or you reboot your machine
   $~ screen
   $~ run_all_your_commands
       # Ctrl + A + D will then detach this screen
   $~ screen -r will reattach it

---

Some other useful commands :

   $~ jobs
        # will show you all processes running right now, but without PID
   $~ ps
        # will show you all processes for actual terminal window

$ servicename &

Using & causes the program to run in the background, instead of blocking the shell until the program ends.
