将sourceDir目录中与sameWithDir目录同名的文件拷贝到targetDir中

cpSameFile

require 'fileutils'
def cpSameFile(sourceDir, targetDir, sameWithDir)
	Dir.foreach(sameWithDir) do |file|
		puts file
		filePath = sourceDir + "/" + file
		targetPath = targetDir + "/" + file
		if file == "." or file == ".." or File.directory?(file)
		else
			if File.exist?(filePath)
				FileUtils.cp filePath, targetPath
			end
		end
	end
end

cpSameFile(ARGV[0], ARGV[1], ARGV[2])
