Creating a directory with Pathname

Wednesday, 16 June 2010 08:53

To create a directory I would typically use File.mkdir however class Pathname can be a convenient alternative e.g.



require 'pathname'



pathname = Pathname.new '/home/james/learning/ruby/fun/today.txt'

#=> #



pathname.exist?

#=> false



pathname.basename

#=> #



#=> #



pathname.dirname.mkdir

#=> 0



# observed directory '/home/james/learning/ruby/fun' was just created

Notes:


  1) There is no Pathname#mkdir_p meaning parent directories will not be created automatically.



  2) If the directory to be created already exists it will create an error 

     e.g. Errno::EEXIST: File exists - /home/james/learning/ruby/fun
