Copying a file from one directory to another with Ruby
提问by 1dolinski
Hey I'm trying to move multiple files from one folder to another. In the FileUtils line I am trying to search through all of the 4 character folders in the destination folder and then paste the file in the folder with the same base name as the file.
嘿，我正在尝试将多个文件从一个文件夹移动到另一个文件夹。在 FileUtils 行中，我试图搜索目标文件夹中的所有 4 个字符文件夹，然后将文件粘贴到与文件具有相同基本名称的文件夹中。
#!/usr/bin/env ruby
require 'fileutils'
my_dir = Dir["C:/Documents and Settings/user/Desktop/originalfiles/*.doc"]
my_dir.each do |filename|
FileUtils.cp(filename, "C:/Documents and Settings/user/Desktop/destinationfolder/****/" + File.basename(filename, ".doc"))
end

Something like this should work.
像这样的事情应该有效。
my_dir = Dir["C:/Documents and Settings/user/Desktop/originalfiles/*.doc"]
my_dir.each do |filename|
name = File.basename('filename', '.doc')[0,4]
dest_folder = "C:/Documents and Settings/user/Desktop/destinationfolder/#{name}/"
FileUtils.cp(filename, dest_folder)
end
You have to actually specify the destination folder, I don't think you can use wildcards.
您必须实际指定目标文件夹，我认为您不能使用通配符。

*is a wildcard meaning "any number of characters", so "****" means "any number of any number of any number of any number of characters", which is probably not what you mean.
*是一个通配符，意思是“任意数量的字符”，所以“ ****”的意思是“任意数量的任意数量的任意数量的任意数量的字符”，这可能不是你的意思。
?is the proper symbol for "any character in this position", so "????" means "a string of four characters only".
?是“此位置的任何字符”的正确符号，因此“ ????”表示“仅包含四个字符的字符串”。

I had to copy 1 in every 3 files from multiple directories to another. For those who wonder, this is how I did it:
我不得不将每 3 个文件中的 1 个从多个目录复制到另一个目录。对于那些想知道的人，我是这样做的：
# frozen_string_literal: true
require 'fileutils'
# Print origin folder question
puts 'Please select origin folder'
# Select origin folder
origin_folder = gets.chomp
# Select every file inside origin folder with .png extension
origin_folder = Dir["#{origin_folder}/*png"]
# Print destination folder question
puts 'Please select destination folder'
# Select destination folder
destination_folder = gets.chomp
# Select 1 every 3 files in origin folder
(0..origin_folder.length).step(3).each do |index|
# Copy files
FileUtils.cp(origin_folder[index], destination_folder)
end
