的Ruby语法错误：文件复制

Question

编写一个小脚本复制一些文件，但我得到的错误：

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

继承人我的代码

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 

所有支架似乎是他们应该是。有什么建议么？

Answer 1

w +应在引号中。

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

Answer 2

您可以使用Fileutils.cp复制文件：

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文件复制，而不是一个明确的清单目录，：

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