的Ruby語法錯誤：文件複製

Question

編寫一個小腳本複製一些文件，但我得到的錯誤：

fileops.rb:6: syntax error, unexpected ')'

繼承人我的代碼

require 'ftools' 

plays = ['RomeoAndJuliet.txt', 'Hamlet.txt', 'TheTempest.txt', 'TheMerchantofVenice.txt', 'AMidSummerNightsDream.txt'] 

plays.each do |filename| 
    File.new("/clean/_cleaned" + filename, w+) 
    File.syscopy(filename, "/clean/_cleaned" + filename) 
end 

所有支架似乎是他們應該是。有什麼建議麼？

Answer 1

w +應在引號中。

File.new("/clean/_cleaned" + filename, "w+") 

Answer 2

您可以使用Fileutils.cp複製文件：

require 'fileutils' 
Fileutils.cp source, dest 

Answer 3

require 'fileutils' 
plays = %w[RomeoAndJuliet Hamlet TheTempest TheMerchantofVenice AMidSummerNightsDream] 
plays.each do |play| 
    Fileutils.cp "#{play}.txt", "/clean/_cleaned#{play}.txt" 
end 

或者，所有.txt文件複製，而不是一個明確的清單目錄，：

Dir['*.txt'].each do |file| 
    Fileutils.cp "#{file}", "/clean/_cleaned#{file}" 
end
