Hi, the Ruby built-in Find module lacks a lot of features the GNU find tools has. I wrote a new one (~170 lines). [http://www.bertram-scharpf.de/tmp/find.rb](http://www.bertram-scharpf.de/tmp/find.rb) Maybe somebody likes it. Bertram ---

> > > [http://raa.ruby-lang.org/project/file-find/](http://raa.ruby-lang.org/project/file-find/) Both seem complementary. Bertram has sorting built-in and is not backwards compatible. After a quick look, Bertram’s code also has silly inefficient things like: dir = (Dir.open @fullpath do |d| d.entries end) - SPECIAL\_DIRS which can just be: dir = Dir.entries(@fullpath) - SPECIAL\_DIRS and the Etc module may be checked several times depending on what you request. Daniel’s has searching based on different much more rich criteria and also breaks backwards compatibility. It lacks sorting and the docs lack simple examples. I did not check the code yet. ---
