Question

我正在尝试创建一个ruby脚本，它将打开一个csv文件，并根据csv文件中每行的内容在目录中搜索文件

e.g

**.csv file**    **directory**
13456            13456.jpg
13567            13456a.jpg
13687            13456b.jpg
                 13567.jpg
                 13687.jpg
                 13687a.jpg

一旦我发现我想将找到的文件复制到名为Keep

的文件夹中

我陷入困境，想弄清楚如何搜索目录

所以我做了一些编码，但我仍然坚持

 #require 'fileutils'
require 'spreadsheet'

input = "/Users/eccleshall/ImageCleanUp/" #where images are stored
output = "/Users/eccleshall/ImageCleanUp/Keep" #where images will be copied to

book = Spreadsheet.open '/Users/eccleshall/Desktop/ImageCleanUpScript/B002.xls' #opens workbook

sheet1 = book.worksheet 0 # sets worksheet

sheet1.each do |row| #for each row output
    puts row

    Dir.glob("/Users/eccleshall/ImageCleanUp/" row).each do|f| #search /Users/eccleshall/ImageCleanUp/ for files startig with row
        puts f
    end
end

我在运行时遇到错误

ImageCleanUp.rb：14：语法错误，意外的tIDENTIFIER，期待'）' ... s / eccleshall / ImageCleanUp /“row”.each do | f | #search / Users / e ...

任何想法？

您可以通过以下方式进行搜索：

require 'fileutils'
Dir.glob('/path_to_file_directory/*.csv').each do |f|  # you can replace the extension you're looking for.
     # the 'f' will give a string representing the path of each file
end

可替换地：

Dir.foreach('/path_to_file_directory/') do |i|
  next if i == '.' or i == '..'
  # do something with each file
end

在文件目录中搜索具有相同起始字符的文件或多个文件
