Recursively descend and rename files

ruby-talk
1

Hello list-
     Could someone please shed some light on this situation for me? I have a huge folder of logos that are named all willy nilly with weird characters and spaces. I need to recursively descend through all of these folders and rename each image so the names only contain [a-z0-9.-]. That part is fine I already have the regex ready to do this. I need to know how to rename these files as I recurse through the directory tree. I have this code so far:

path = "/Volumes/Users/ez/LOGOS"
files = []
require 'find'
Find.find(path) do |file|
   files << file if file=~ /.eps$/
end

This leaves me with an array of good filenames but they have their complete path as well. What I need help with is for each file, pul just the file name out of the path, do some gsub's on it and then rename it with the output of the gsubs. So after all is said and done the original files will be renamed to be compliant with the regexes I run on each one.

Can some one please point me in the right direction?

Thanks-

You could just do the operation as you go:

   Find.find(path) do |file|
     fix(file) if /.eps$/.match(file) # or whatever
   end

The fact that it's got the path attached shouldn't matter for the
renaming operation, since you're not chdir'ing.

require 'ftools'

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

def fix_name(basename)
  # whatever fixes the name
  basename.gsub(/s/,'xxx')
end
__END__

Check out the FileUtils module for the OS stuff like copying and moving,
and File.basename for the path splitting.

Thanks for everyones Ideas on this one. It works perfectly. If anyone has the need to do something similar heres the code:

---start--------
#!/usr/local/bin/ruby
# recursively descend through directories and change filenames to be webserver compliant based on a regex.

require 'find'
require 'ftools'

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.-]*/, '')
         name.gsub!(/^-/,'')
end

path = "/Volumes/Users/ez/LOGOS" # change me to the path of the root folder you want to start from.
Find.find(path) do |file|
   rename(file)
end

----end---------
