Issue #4563 has been updated by Daniel Berger. I was expecting "1", in part because of the example from the pickaxe, and also because that's what JRuby returns. OS X 10.4 returns a simple index, too. However, I now see it's not necessarily just a simple index, depending on the platform. ---------------------------------------- Bug #4563: Dir#tell broken http://redmine.ruby-lang.org/issues/4563 Author: Daniel Berger Status: Rejected Priority: Normal Assignee: Category: Target version: ruby -v: ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-linux] Dir#tell is not returning the correct value after a read: dir = Dir.new(Dir.pwd) p dir.tell # => 0 dir.read p dir.tell # => 56334832 -- http://redmine.ruby-lang.org
