在嵌套目录结构中查找文件

I am attempting to find a file by its name within a directory. I am not sure what the best approach to this problem is. The file could be nested in other directories within the root directory.

我正在尝试在一个目录中按文件名查找文件。我不知道解决这个问题的最佳方法是什么。该文件可以嵌套在根目录的其他目录中。

3 个解决方案

#1

You can use Dir.glob, for example:

您可以使用Dir。一团,例如:

Dir.glob(File.join("**","*.rb"))

It will recursively look for "*.rb" files in your current directory.

它会递归地寻找“*”。当前目录中的rb文件。

#2

this should work for you:

这应该对你有用:

require 'find'

file_name = /log\Z/
path = './'

found_files = Find.find(path).inject([]) do |files, entry|
  File.file?(entry) && File.basename(entry) =~ file_name ?
    files << entry : files
end

p found_files
#=> ["./Maildir/dovecot.index.log", "./pgadmin.log"]

change file_name and path to your needs.

根据需要更改file_name和路径。

#3

You could use Dir.glob or Dir[]:

您可以使用Dir。水珠或Dir[]:

Dir['the_directory/**/the_filename']

The ** matches 0 or more directories recursively. It returns an array of filenames that match.

**会递归地匹配0或多个目录。它返回匹配的文件名数组。
