Running apps or commands in the background.

[guitarmaster18]

How would you run say... a UNIX command in terminal as a background process, but not be able to see it running unless you access it through Activity Monitor? I'm looking for something that I can input into one of my little UNIX apps that sets the desktop as a screen saver. I'm looking for a way I can run that without noticing terminal open. Any thoughts?

If is one application you will run from terminal, you can use &
example

>./MyApp &

that will force the application to run on the background.
Just make sure it doesn't have outputs to screen because those will appear while you are working.

I usually need to run long programs and collect the data, so what I do is redirect the output to a file and run it in the background.

>./MyApp > out.dat &
