code:

# Dir.foreach(“bad”) do |f| puts “#{f}: #{File.size f}” end

Each filename in the directory “bad” is displayed along with the file  
size.

I know the file.size works because I tried it with an static name and  
displayed fine.

the error I got

# ============ lib/dir\_test.rb:6:in `size': No such file or directory - IMG_0964.jpg (Errno::ENOENT) from lib/dir_test.rb:6 from lib/dir_test.rb:5:in`foreach’ from lib/dir\_test.rb:5

Add ‘bad/’ to each filename. E.g:

Dir.foreach(“bad”) do |f|  
puts “#{f}: #{File.size(‘bad/’+f)}”  
end

If you did:

Dir[“bad/\*”].each do |f|  
…  
end

in the first place, you wouldn’t need to add the ‘bad/’. I was  
originally  
going to reply to suggest adding it, but then I though .foreach() would  
do  
that for ya. Guess not.
