def ascend

Iterates over and yields a new Pathname object for each element in the given path in ascending order.
Example
Pathname.new('/path/to/some/file.rb').ascend {|v| p v} #<Pathname:/path/to/some/file.rb> #<Pathname:/path/to/some> #<Pathname:/path/to> #<Pathname:/path> #<Pathname:/> Pathname.new('path/to/some/file.rb').ascend {|v| p v} #<Pathname:path/to/some/file.rb> #<Pathname:path/to/some> #<Pathname:path/to> #<Pathname:path>
Returns an Enumerator if no block was given.
enum = Pathname.new("/usr/bin/ruby").ascend
# ... do stuff ...
enum.each { |e| ... }
# yields Pathnames /usr/bin/ruby, /usr/bin, /usr, and /.
