[Ruby] Launching script/runner from within Rails

[ben wiseley]

You can shell out using the ` (tick under the tilde key)

we use this to validate image file formats... like so:

    file_formats = ["JPEG","PNG","GIF","TIFF","PC bitmap"]
    res = `file #{filename}`
    file_formats.each do |ff|
      if res.include?(ff)
        return
      end
    end

so you should be able to use that on script runner type stuff.

This isn't async though - which is what you need, right?  Fire and forget?
