Subject: Simple regex question.

Hello.
I need to parse through thousands of TIFF files and do some re-naming.
These files have underscores in them followed by a sequential number. I
need to grab just the "root" of the filename, without the underscore or
the numbers.
  Dir.chdir("L:/infocontiffs/ehs-g7917741")
  files      = Dir.glob("*.tiff")
  file      = files[0]
  puts file
  file      = file.gsub(/^(.*)_[0-9]+\.tiff/, "#{$1}")
  puts file
What I get with this is:
        ehs-g7917741_01.tiff
Why doesn't it give me my root filename?
Thanks,
Peter
