Script to delete all the git tags from a repository (both local and remote). Take care, because it really does what it says :)

delete_git_tags.rb

def delete_local_tags
  `git tag`.split(/\n/).each do |tag| 
    %x{git tag -d #{tag}}
  end
end

def delete_remote_tags
  `git ls-remote --tags origin`.split(/\n/).each do |remote_tag_line| 
    remote_tag_line =~ /\/([^\/]*)$/
    %x{git push origin :refs/tags/#{$1}}
  end
end
