Hi all,

I just thought I’d drop this one in for any newbie’s playing around  
with directory listings…

me@somehost\> find /somedir \> results

File.open("./results").each do |file|  
puts file unless File.directory(file)  
end

… What do we think the output should be if given that /somedir  
contains both directories and files…

And why does this give you a different result…

require ‘find’

Find.find("./results").each do |file|  
puts file unless File.directory(file)  
end

Yep… probably _extrememly_ obvious to the oldtimers… but drove me  
nuts…\n

Hint: …chomp…

Opps… correction…

require ‘find’

Find.find("./somedir").each do |file|  
puts file unless File.directory(file)  
end
