在Ruby 2.5中，您现在可以使用Dir.children。它以数组的形式获取文件名，但“.”除外。和“..”

示例：

Dir.children("testdir")   #=> ["config.h", "main.rb"]

Http://ruby-doc.org/core-2.5.0/Dir.html#method-c-children

这对我很管用：

如果您不想要隐藏文件[1]，请使用Dir[]：

# With a relative path, Dir[] will return relative paths

# as `[ './myfile', ... ]`

# 

Dir[ './*' ].select{ |f| File.file? f } 

# Want just the filename?

# as: [ 'myfile', ... ]

# 

Dir[ '../*' ].select{ |f| File.file? f }.map{ |f| File.basename f }

# Turn them into absolute paths?

# [ '/path/to/myfile', ... ]

# 

Dir[ '../*' ].select{ |f| File.file? f }.map{ |f| File.absolute_path f }

# With an absolute path, Dir[] will return absolute paths:

# as: [ '/home/../home/test/myfile', ... ]

# 

Dir[ '/home/../home/test/*' ].select{ |f| File.file? f }

# Need the paths to be canonical?

# as: [ '/home/test/myfile', ... ]

# 

Dir[ '/home/../home/test/*' ].select{ |f| File.file? f }.map{ |f| File.expand_path f }

现在，目录条目将返回隐藏文件，并且您不需要通配符Asterix(您可以只传递带有目录名的变量)，但它将直接返回基本名称，因此File.xxx函数将不起作用。

# In the current working dir:

# 

Dir.entries( '.' ).select{ |f| File.file? f }

# In another directory, relative or otherwise, you need to transform the path

# so it is either absolute, or relative to the current working dir to call File.xxx functions:

# 

home = "/home/test"
Dir.entries( home ).select{ |f| File.file? File.join( home, f ) }

[1].dotfile在Unix上，我不知道Windows

To get all files (strictly files only) recursively:

Dir.glob('path/**/*').select { |e| File.file? e }

Or anything that's not a directory (File.file? would reject non-regular files):

Dir.glob('path/**/*').reject { |e| File.directory? e }

Alternative Solution

Using Find#find over a pattern-based lookup method like Dir.glob is actually better. See this answer to "One-liner to Recursively List Directories in Ruby?".

以下代码片断准确地显示了目录中文件的名称，跳过了子目录和"."、".."点分文件夹：

Dir.entries("your/folder").select { |f| File.file? File.join("your/folder", f) }

Dir.entries(folder)

示例：

Dir.entries(".")
