[systemd-devel] guidance on how to start systemctrl with service files in specified locations

[lux-integ]

greetings


I am learning to use systeMD.
my computing machine has these:-
--cpu- -amd64
--os blfsLinux linux-3.11.6, systemd-204 ( I think).

I have created some   systeMD service files for programs (call  a typical one  
noise.service')  and I placed then in  say  /path/to/bang.


Now I want to start noise.service after  the main systemd booting  is over.  


I would like to know if one can execute the command systemctrl like so:-

systemcrl  /path/to/bang/noise.service

and if hot 
how otherwise

thanks in advance
