instance method

Find#prune

() -> void

Find.prune

# File tmp/rubies/ruby-4.1.0-preview1/lib/find.rb, line 108
def prune
  throw :prune
end

This method is meaningful only within a block given with Find.find.

Inside such a block, “prunes” the traversed file tree by not descending into the current directory:

Example

files = []
Find.find('.') do |path|
  Find.prune if File.basename(path) == 'test'
  next unless File.file?(path) && File.extname(path) == '.rb'
  files << path
end
files.size    # => 6690
files.take(3) # => ["./KNOWNBUGS.rb", "./array.rb", "./ast.rb"]
