Preview Ruby 4.1 is a preview. It can change before the final release. Switch to Ruby 4.0 →

class method

Dir.[]

(*::path patterns, ?base: ::path?, ?sort: bool) -> ::Array[::String]

Dir[*patterns, base: nil, sort: true] → array

# File tmp/rubies/ruby-4.1.0-preview1/dir.rb, line 223
def self.[](*args, base: nil, sort: true)
  Primitive.dir_s_aref(args, base, sort)
end

Like Dir.glob, but does not accept keyword argument flags, and may take multiple patterns as arguments:

Example

Dir['*.rb', '*.h'].take(3) # => ["KNOWNBUGS.rb", "array.rb", "ast.rb"]

Ruby version changes

3.0
- Dir.glob and Dir.[] now sort the results by default, and accept the sort: keyword option. [Feature #8709]
