Copy all files and folders except few in Ruby

I was wondering if I can use FileUtils.cp_r method to copy all the files and directories from source to target except .tar files. Can someone give me an example for better understanding?

Thanks

Sure but you'd have to implement some kind of filter first like this:

[8] pry(main)> Dir.glob("**/*")
=> ["bin", "CODE_OF_CONDUCT.md", "Gemfile", "Gemfile.lock", "hello.tar", "lib", "LICENSE.txt", "mygem.gemspec", "Rakefile", "README.md", "spec"]

That gave us all the files in that directory and subsequent directories(thanks ndn for that tip), now let's filter out that hello.tar:

files = Dir.glob("**/*").reject { |file| file.end_with?(".tar") }

Now we can pass an array into FilteUtils::cp_r

FileUtils.cp_r(files, destination)
