Module | Find |
In: |
lib/find.rb

The Find module supports the top-down traversal of a set of file paths.
For example, to total the size of all files under your home directory, ignoring anything in a "dot" directory (e.g. $HOME/.ssh):
require 'find' total_size = 0 Find.find(ENV["HOME"]) do |path| if FileTest.directory?(path) if File.basename(path)[0] == ?. Find.prune # Don't look any further into this directory. else next end else total_size += FileTest.size(path) end end
Calls the associated block with the name of every file and directory listed as arguments, then recursively on their subdirectories, and so on.
See the Find module documentation for an example.
