When I execute A & B and then cancel with ^C only B gets killed, and A runs on the background. How can I execute A & B as one command I can kill without killing the background job ?

    Perhaps you should specify what behavior you want when you say "execute A & B as 'one command.'" Do you mean you want them to execute sequentially rather than concurrently? To have the same PID (which is impossible)? To have one be a child of the other? To have one die when the other is killed? "One command" is quite vague; A and B are separate simple commands however you connect them (whether in a pipeline, a list, a compound command, or other method.) – Wildcard Dec 12 '16 at 1:45

  • They should run both simultanuously. And one has to die when the other is killed – Mehdiway Dec 12 '16 at 1:48

The solution : Run it as (A & B) with parentheses
