The Ruby file class has a rename() method. So you could search for the files you want to rename then use the File.rename() method to rename all of them.

Example:

product_name = "Some String";
id = 0;

filenames = Dir.glob("*.jpg")

filenames.each do |filename|
    File.rename(filename, product_name + id.to_s)
    id += 1
end

Here's a little tidbit for you. Maybe it will help out. http://rtdptech.com/2010/08/ruby-shell-script-to-rename-files-in-a-folder/

I used something like this for a quickie because I wanted to use the rdoc/ri files to make little examples. I copied some directories to another location and the wanted to change the extension from *.ri to *.rb so I could put my runnable ruby code in.

here's the command line version

$ ruby -e "Dir.glob('*/*.ri').each {|i| File.rename(i, i.gsub('ri', 'rb'))}"

and here is file version

Dir.glob('*/*.ri').each {|i| File.rename(i, i.gsub('ri', 'rb'))}
