How to run a ruby shell script that shows some information, then asks for input and goes background?

I have a ruby shell script that I want to run on background. However, before going to background I need to ask for an user input.

Is it possible? How can it be achieved?

Thanks in advance!

Solution

  • Here's a simple example:

    def do_stuff(input)
  puts "Input received: #{input}"
  sleep 10
end

print "Enter input value: "
input = gets
pid = fork { do_stuff(input) }
puts "test.rb started, pid: #{pid}"
Process.detach pid

    Note the use of fork to start a new process, and detach to allow the subprocess to continue running while the main process exits.

    Some platforms (Windows) don't support fork.
