How to create Ruby subprocess

• Do I want to return to my Ruby script at all?
  • No! Use Kernel exec: exec()
  • Yes! Is it OK to block until the process completes?
    • Yes! Do I need the program’s output to be returned?
      • Yes! Use Kernel backtick: `` or %x{}
      • No! Use Kernel system: system() - outputs to stdout.
    • No! Do I need to interact with the output?
      • No! Use Kernel fork: fork() - seperate child process (daemonize).
      • Yes! Do I want stderr?
        • No! Use IO popen: IO.popen() (or use 2>&1 if you want both stderr and stdout).
        • Yes! Do I want stderr in a separate stream?
          • No! Use PTY spawn: PTY.spawn() (emulates terminal).
          • Yes! Use Open3 popen3: Open3.popen3()
