glob is a class method of Dir, not an instance method.

irb(main):002:0> Dir::glob('/tmp/zz/a?')
=> ["/tmp/zz/aa"]

If you run 'ri Dir' from the command-line, you can see glob appears under
'Class methods'. Running 'ri Dir::glob' gives example usage. glob returns
an array of strings, but if you want Files, you can do this:

irb(main):007:0> Dir::glob('/tmp/zz/a*').map { |f| File.new f }
=> [#<File:/tmp/zz/a>, #<File:/tmp/zz/aa>]

(though perhaps there's a better way; I haven't done too much with Dir/File
myself..)
