You're looking at the docs for the class method File.basename, but you're calling basename on an instance of File referenced by f puts File.basename('myfile') or better: puts File.basename('/some/long/path/to/myfile') -Rob Rob Biedenharn Rob(a)AgileConsultingLLC.com http://AgileConsultingLLC.com/ rab(a)GaslightSoftware.com http://GaslightSoftware.com/
