I am trying to write a simple script that downloads a music file from the internet. For example: if i want to download [http://cdn.stereogum.com/mp3/My%20Morning%20Jacket%20-%20Celebration%20(Live).mp3](http://cdn.stereogum.com/mp3/My%20Morning%20Jacket%20-%20Celebration%20(Live).mp3) how exactly would you do it? I found someone who was able to download a flickr photo using this script: require ‘net/http’ Net::HTTP.start(“[farm1.static.flickr.com](http://farm1.static.flickr.com)”) { |http| resp = http.get(“/92/218926700\_ecedc5fef7\_o.jpg”) open(“fun.jpg”, “wb”) { |file| file.write(resp.body) } } puts ‘Downloaded’ With a slight modification shouldn’t this work for the music file? What makes downloading a photo any different than an mp3 file? require ‘net/http’ Net::HTTP.start(“[cdn.stereogum.com](http://cdn.stereogum.com)”) { |http| resp = http.get(“/mp3/My Morning Jacket - Celebration (Live).mp3”) open(“Celebration.mp3”, “wb”) { |file| file.write(resp.body) } } puts “the song has been downloaded” Why doesn’t it work? What needs to be changed? Any help would be great! Thanks. ---

Thank you guys very much! I was able to get it to work by fixing my path. I wasn’t able to get it to work using alternate way even after changing the URL. I get the following error. syntax error, unexpected kDO, expecting $end do |src| Just out of curiosity- how can I fix this. I would like to know so that I can work through it and figure out exactly what the script is doing and compare it to the previous script. Thanks again! ---
