Ruby中遍历目录的实现方法

#!/usr/bin/ruby
def traverse(filepath)
    if File.directory?(filepath)
      puts "Dirs:" + filepath
      Dir.foreach(filepath) do |filename|
        if filename != "." and filename != ".."
          traverse(filepath + "/" + filename)
        end
      end
    else
      puts "Files:" + filepath
    end
  end
  
#traverse("d:/vmware")
traverse("/usr/local/src")

#!/usr/bin/ruby
require  'find'
Find.find("/usr/local/src") do |filename|
  p filename
end
