Thread: My own terminal > Running a background process

Hello,

I have been coding my own terminal over the last few weeks and I've stumbled upon a little problem.

I can run programs from the terminal fine but when I try to run something in the background, for example, "firefox &" it still opens in the foreground.

However if I put the '&' at the beginning, it does open in the background.

Does anyone know the correct code to run things in the background?

It involves a different system call - what OS are you using? In *nix, you would fork(), then exec() in the child process. On windows, have a look at the spawn() family of functions. I'm a little confused about your question, though - you already have programs running in the background, it's just the placement of the '&'. So, what's your command parser doing? Or are you just passing all input to system()?

I think it was run as a background process only , but it might print some lines which makes you to think as a foreground process.

If my understanding is right ?
Please try this $ firefox >/dev/null &
