How to tell Dir from file?

ruby-talk
1

Hello list-
     I have the following script that recursively descends through some directories and changes the name of a bunch of logos to be webserver compliant.

require 'find'
require 'ftools'
path = "/Volumes/Users/ez/LOGOS/"

def rename(filename)
   new_name = File.join(File.dirname(filename), fix_name(File.basename(filename)))
   File.move(filename, new_name)
end

def fix_name(name)
         name.gsub!(/[\s_]/, "-")
         name.downcase!
         name.gsub!(/[^a-z0-9.-]*/, '')
end

Find.find(path) do |file|
   rename(file)
end

I need to know how to tell the difference between a file with no extension and a directory name. The script works perfectly right now except when it first runs into a directory it makes a 0 byte file with the same name within that directory. I need to know how to test whether the current iteration contains an actual file or is a directory so I can skip renaming it.

You help is much appreciated.

Have a look at 'ri test' or 'ri File.directory?'.

HTH,
Guillaume.
