Question

I’m attempting to execute the following bash command on some images using Ruby:

class Pingcrush
  def initialize
    Dir.foreach('drawable') do |item|
      next if item == '.' or item == '..'
      # do work on real items
      if item.end_with?(".png") then
        %x["wine pngcrush.exe -brute drawable/#{item} new/#{item}"]
      end
    end
  end
end
Pingcrush.new

The directory I am in is the parent to both drawable and new, however, when when I attempt to run the script I always get the same error:

sh: wine pngcrush.exe -brute drawable/feed_cl.png new/feed_cl.png: not found

Why is this happening? I tried switching around the path I’m calling in Ruby and can’t seem to make this work.

Its executing your shell but can’t find wine. Try setting the full path to where wine is installed.

which wine
