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 loop do // Some code sleep 1.minute end end Process.detach(pid)
In my case, I just needed some code to run each minute, but it is part of a Rails app, so I didn't just want to start it with cron every minute (Rails loading is expensive). Neat eh?
