Why does Ruby seem to access files in a directory randomly?

Question

Is this by design?

Here\'s the code:

class FileRenamer
    def RenameFiles(folder_path)    
        files = Dir.glob(folder_path + \"/*\")
    end
en         


        

Answer 1

The answer from Scott is out of date. I ran Dir.glob on Mac OS 10.15.6 Catalina, and the files were not returned in alphabetical order. According to the ruby docs, the ordering is determined by the OS.

Note that the pattern is not a regexp, it's closer to a shell glob. See File.fnmatch for the meaning of the flags parameter. Case sensitivity depends on your system (File::FNM_CASEFOLD is ignored), as does the order in which the results are returned.
