Here's a neat thing I found. I needed a small bit of Ruby code to run continuously in the background, but because of how Capistrano can't seem to work well with "nohup" and "&" (background job), my ruby script itself needed to be able to fork and detach from the terminal. Here's how you do it:



#!/usr/bin/ruby



pid = fork do

  Signal.trap('HUP', 'IGNORE') # Don't die upon logout



  loop do



    // Some code



    sleep 60

  end

end



Process.detach(pid)
