you can view running processes with the "ps" command, use "ps aux" to view ALL running processes (see "man ps" for more info). you can use this command: "ps aux | grep run" to view only the "run" process. for realtime monitoring running processes, use the "top" command. you can run different scripts in background, but if you logout the terminal (or xterm) the process will die, because it's a child process of the terminal.
